Pololu AltIMU-10 v5 Gyro, Accelerometer, Compass, and Altimeter
The Pololu AltIMU-10 v5 is a compact board that combines ST’s LSM6DS33 3-axis gyroscope and 3-axis accelerometer, LIS3MDL 3-axis magnetometer, and LPS25H digital barometer to form an inertial measurement unit (IMU) and altimeter. These sensors are great ICs, but their small packages make them difficult for the typical student or hobbyist to use. They also operate at voltages below 3.6 Volt, which can make interfacing difficult for microcontrollers operating at 5 Volt. The AltIMU-10 v5 addresses these issues by incorporating additional electronics, including a voltage regulator and a level-shifting circuit, while keeping the overall size as compact as possible. The board ships fully populated with its SMD components, including the LSM6DS33, LIS3MDL, and LPS25H.
Attitude and Heading Reference System (AHRS)
An attitude and heading reference system (AHRS) uses an inertial measurement unit (IMU) consisting of microelectromechanical system (MEMS) inertial sensors to measure the angular rate, acceleration, and Earth’s magnetic field. These measurements can then be used to derive an estimate of the object’s attitude. An AHRS typically includes a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer to determine an estimate of a system’s orientation. Each of these sensors contribute different measurements to the combined system and each exhibit unique limitations.

SparkFun Triple Axis Magnetometer Breakout – HMC5883L
This is a breakout board for Honeywell’s HMC5883L, a 3-axis digital compass. Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied. The breakout board includes the HMC5883L sensor and all filtering capacitors as shown. The power and 2-wire interface pins are all broken out to a 0.1 inch pitch header.

Pololu 5 Volt Step-Up Voltage Regulator U1V10F5
This tiny U1V10F5 switching step-up voltage regulator efficiently generates 5 Volt from input voltages as low as 0.5 Volt. Unlike most boost regulators, the U1V10F5 automatically switches to a linear down-regulation mode when the input voltage exceeds the output.
Ultrasonic Distance Sensor – HC-SR04 (5 Volt)
This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2 Centimetres to 400 Centimetres of non-contact measurement functionality with a ranging accuracy that can reach up to 3 Millimetres. 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). This sensor has additional control circuitry that can prevent inconsistent “Bouncy” data depending on the application.

SparkFun 9DoF IMU Breakout – LSM9DS1
The SparkFun LSM9DS1 Breakout is a versatile, motion-sensing System-In-A-Chip. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer, nine degrees of freedom (9DOF) on a single board. The LSM9DS1 from STMicroelectronics is equipped with a digital interface, but even that is flexible. This IMU-In-A-Chip is so cool we put it on the quarter-sized breakout board you are currently viewing.
The LSM9DS1 is one of only a handful of IC’s that can measure three key properties of movement, angular velocity, acceleration, and heading, in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an object’s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/z, angular rotation in x/y/z, and magnetic force in x/y/z. The LSM9DS1 Breakout has labels indicating the accelerometer and gyroscope axis orientations, which share a right-hand rule relationship with each other.

SparkFun Environmental Combo – CCS811/BME280
The SparkFun CCS811/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensing needs with the popular CCS811 and BME280 ICs. This unique breakout provides a variety of environmental data, including barometric pressure, humidity, temperature, TVOCs and equivalent eCO2 levels.
The CCS811 is an exceedingly popular sensor, providing readings for equivalent eCO2 in the parts per million (PPM) and total volatile organic compounds in the parts per billion (PPB). The CCS811 also has a feature that allows it to fine-tune its readings if it has access to the current humidity and temperature. Luckily for us, the BME280 provides humidity, temperature and barometric pressure. This allows the sensors to work together to give us more accurate readings than they’d be able to provide on their own. We also made it easy to interface with them via I2C.

SparkFun IR Receiver – TSOP85
This is a very small infrared receiver based on the TSOP85 receiver from Vishay. This receiver has all the filtering and 38kHz demodulation built into the unit. Simply point a IR remote at the receiver, hit a button, and you’ll see a stream of 1s and 0s out of the data pin.

SparkFun Digital Temperature Sensor – TMP102
The TMP102 is an easy-to-use digital temperature sensor from Texas Instruments. The TMP102 breakout allows you to easily incorporate the digital temperature sensor into your project. While some temperature sensors use an analog voltage to represent the temperature, the TMP102 uses the I2C bus of the Arduino to communicate the temperature. Needless to say, this is a very handy sensor that doesn’t require much setup.
The TMP102 is capable of reading temperatures to a resolution of 0.0625°C, and is accurate up to 0.5°C. The breakout has built-in 4.7k Ohm pull-up resistors for I2C communications and runs from 1.4V to 3.6V. I2C communication uses an open drain signaling, so there is no need to use level shifting.

SparkFun Line Sensor QRE1113 (Analog)
This version of the QRE1113 breakout board features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. This tiny board is perfect for line sensing applications and can be used in both 3.3V and 5V systems.
The board’s QRE1113 IR reflectance sensor is comprised of two parts – an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate. A 100 Ohm resistor is on-board and placed in series with the LED to limit current. A 10k Ohm resistor pulls the output pin high, but when the light from the LED is reflected back onto the phototransistor the output will begin to go lower. The more IR light sensed by the phototransistor, the lower the output voltage of the breakout board.
These sensors are widely used in line following robots, white surfaces reflect much more light than black, so, when directed towards a white surface, the voltage output will be lower than that on a black surface.

Pololu Carrier for MQ Gas Sensors
This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, power and analog voltage output—that are broken out with a 0.1″ spacing, making the board compatible with 0.1″ headers and standard breadboards and perfboards. This board has two mounting holes and provides convenient pads for mounting the gas sensor’s required sensitivity-setting resistor.
Alcohol Gas Sensor – MQ-3
This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration.
How does this relate to the breath? It turns out that there is a standard conversion from breath alcohol content to BAC that is employed by commercial breathalyzers. Our formula for calculating BAC from the alcohol measured in the breath is:
% BAC = Breath mg/L * 0.21
