ams CCS811 Ultra-Low Power Digital Gas Sensor for Monitoring Indoor Air Quality
The CCS811 is an ultra-low power digital gas sensor solution which integrates a metal oxide (MOX) gas sensor to detect a wide range of Volatile Organic Compounds (VOCs) for indoor air quality monitoring with a microcontroller unit (MCU), which includes an Analog-to-Digital converter (ADC), and an I²C interface.
CCS811 is based on ams unique micro-hotplate technology which enables a highly reliable solution for gas sensors, very fast cycle times and a significant reduction in average power consumption. The integrated MCU manages the sensor drive modes and raw sensor data measured while detecting VOCs. The I²C digital interface significantly simplifies the hardware and software design, enabling a faster time to market.
CCS811 supports intelligent algorithms to process raw sensor measurements to output a TVOC value or equivalent CO2 (eCO2) levels, where the main cause of VOCs is from humans. CCS811 supports multiple measurement modes that have been optimised for low-power consumption during an active sensor measurement and idle mode extending battery life in portable applications.
Applications
This device can be mainly used for indoor air quality monitoring in:
- Smartphones
- Wearables
- Home and building automation
- Accessories

Bosch Sensortec BME280 – Combined Humidity And Pressure Sensor
The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles. Its small dimensions and its low power consumption allow the implementation in battery driven devices such as handsets, GPS modules or watches. The BME280 is register and performance compatible to the Bosch Sensortec BMP280 digital pressure sensor. The BME280 achieves high performance in all applications requiring humidity and pressure measurement. These emerging applications of home automation control, in-door navigation, E-Textiles, fitness as well as GPS refinement require a high accuracy and a low TCO at the same time. The humidity sensor provides an extremely fast response time for fast context awareness applications and high overall accuracy over a wide temperature range. The integrated temperature sensor has been optimized for lowest noise and highest resolution. Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature. The sensor provides both SPI and I²C interfaces.

SparkFun Micro OLED Breakout (Qwiic)
The SparkFun Qwiic Micro OLED Breakout is a Qwiic-enabled version of our popular Micro OLED display. The small monochrome, blue-on-black OLED screen presents incredibly clear images for your viewing pleasure. It’s micro, but it still packs a punch the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next project and displaying diagnostic information without resorting to a serial output, all with the ease of use of our own Qwiic Connect System.
This version of the Micro OLED Breakout is exactly the size of its non-Qwiic sibling, featuring a screen that is 64 pixels wide and 48 pixels tall and measuring 0.66 inch across. But it has also been equipped with two Qwiic connectors, making it ideal for I2C operations. We’ve also added two mounting holes and a convenient Qwiic cable holder incorporated into a detachable tab on the board that can be easily removed thanks to a v-scored edge. We’ve even made sure to include an I2C pull-up jumper and ADDR jumper on the back of the board, so if you have your own I2C pull-ups or need to change the I2C address of the board, you have options.

HC-SR04 Ultrasonic Sensor
This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.
There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find this sensor very easy to set up and use for your next range-finding project. This sensor has additional control circuitry that can prevent inconsistent “bouncy” data depending on the application.

MicroSD Card Breakout Board+
Not just a simple breakout board, this microSD adapter goes the extra mile – designed for ease of use.
- -Onboard 5v->3v regulator provides 150mA for power-hungry cards
- -3v level shifting means you can use this with ease on either 3v or 5v systems
- -Uses a proper level shifting chip, not resistors: less problems, and faster read/write access
- -Use 3 or 4 digital pins to read and write 2Gb+ of storage
- -Activity LED lights up when the SD card is being read or written
- -Push-push socket with card slightly over the edge of the PCB so its easy to insert and remove
- -Comes with 0.1″ header so you can get it on a breadboard or use wires
To use with an Arduino, connect GND to ground, 5V to 5V, CLK to pin 13, DO to pin 12, DI to pin 11, and CS to pin 10.

ChronoDot – Ultra-Precise Real Time Clock – v2.1
The ChronoDot RTC is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC. It includes a CR1632 battery, which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required.
The top side of the Chronodot now features a battery holder for 16mm 3V lithium coin cells. It pairs particularly well with CR1632 batteries. The DS3231 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continously monitored, and the capacitors are adjusted to maintain a stable frequency. Other RTC solutions may drift minutes per month, especially in extreme temperature ranges…the ChronoDot will drift less than a minute per year. This makes the ChronoDot very well suited for time critical applications that cannot be regularly synchronized to an external clock.

RGB LCD Shield 16×2 Character Negative Display
With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino. The shield is designed for Arduinos Uno. It uses the I2C pins at Analog 4 and Analog 5.
At this time, the library and shield can control the RGB backlight of our character LCDs by turning each LED on or off. This means you can display the following colors: Red, Yellow, Green, Teal, Blue, Violet, White and all off. This shield is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer.
Adjusting Contrast
The shield uses a character LCD with an external contrast potentiometer. The first time you use it, adjust the potentiometer in the bottom right until you see the text clearly.

Pololu Adjustable Step-Up Voltage Regulator U1V11A
This compact U1V11A switching step-up voltage regulator efficiently boosts input voltages as low as 0.5 V to an adjustable output voltage between 2 V and 5.25 V. Unlike most boost regulators, the U1V11A offers a true shutdown option that turns off power to the load, and it automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1 inch spacing, making this board compatible with standard solderless breadboards.
NeoPixel Stick – 8 x 5050 RGB LED
Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC.

IMU
Accelerometers, gyroscopes and magnetometer are great, but alone they don’t give you quite enough information to be able to comfortably calculate things like orientation, position, and velocity. To measure those and other variables many people combine the two sensors, to create an inertial measurement unit (IMU) which provides two to nine degrees of freedom (DOF). IMUs are widely used in devices that require knowledge of their exact position, for example robotic arms, guided missiles, and tools used in the study of body motion.
IMUs can really be broken down into two classes: simple IMU combo boards, which just mount an accelerometer, gyroscopes and magnetometer onto a single PCB, and more complex units that interface a microcontroller with the sensors to produce a serial output. If you’ve glanced over the previous sections, you should know what kind of specifications to be looking for in IMUs: the number of axes (both for the accelerometer, gyroscopes and magnetometer), the measuring range of the sensors, and the interface.
Pololu MinIMU-9 v5 Gyro, Accelerometer, and Compass
The Pololu MinIMU-9 v5 is an inertial measurement unit (9DoF IMU) that packs an LSM6DS33 3-axis gyro and 3-axis accelerometer and an LIS3MDL 3-axis magnetometer onto a tiny board. An I²C interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation. The MinIMU-9 v5 board includes a voltage regulator and a level-shifting circuit that allow operation from 2.5 to 5.5 V, and the pin spacing makes it easy to use with standard solderless breadboards and perfboards.
STMicroelectronics LSM6DS33
The LSM6DS33 is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope performing at 1.25 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience for the consumer. ST’s family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes.
STMicroelectronics LIS3MDL
The LIS3MDL is an ultra-low-power high-performance three-axis magnetic sensor. The LIS3MDL has user-selectable full scales of gauss. The self-test capability allows the user to check the functioning of the sensor in the final application. The device may be configured to generate interrupt signals for magnetic field detection.
