SparkFun Triple Axis Accelerometer Breakout – ADXL335
Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors – the holy grail of accelerometers. The ADXL335 is a triple axis MEMS accelerometer with extremely low noise and power consumption only 320 uA. The sensor has a full sensing range of +/- 3g. There is no on-board regulation, provided power should be between 1.8 and 3.6 Volt. Board comes fully assembled and tested with external components installed. The included 0.1 uF capacitors set the bandwidth of each axis to 50 Hz.

Global Positioning System (GPS)
The Global Positioning System (GPS) is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.
GPS Receiver – GP-20U7
The GP-20U7 is a compact GPS receiver with a built-in high performances All-In-One GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.

SparkFun Environmental Combo Breakout – 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. To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system.
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.

Humidity and Temperature Sensor – RHT03
The RHT03 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature.
MQ Series Gas Sensor
The description of each MQ series gas sensor and its uses that follows will be helpful to anybody who wants to understand the foundations of gas sensing technology. The MQ Series Gas Sensor is a revolutionary technology designed for the detection of combustible gases, such as those used in industry and manufacturing. MQ sensor working principle involves detecting changes in electrical conductivity when specific gases come into contact with the sensor’s sensing element. This variety of semiconductor gas sensors makes it possible to measure concentrations of gasses such as alcohol, methane, propane, butane, and carbon monoxide.
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 +3-5 Volt. This board has two mounting holes and provides convenient pads for mounting the gas sensor’s required sensitivity-setting resistor.

Fermion: BLE Sensor Beacon
Fermion: BLE Sensor Beacon, a wireless beacon that broadcasts sensor data via Bluetooth, with built-in 11-bit ADC acquisition and I2C write/read functionality, can be connected to digital or analogue sensors for data acquisition and broadcasting. Sensor data broadcasted by the beacon can be accessed within the beacon’s broadcast range using mobile phones, ESP32 and other devices that support BLE reception.
Fermion: BLE sensor beacons integrate low-power Bluetooth 5.3 technology with self-configurable data formats, such as iBeacon, Eddystone, user-defined, and more. The data format of the beacon broadcast, the content of the broadcast, the broadcast interval and so on can be configured through the graphical interface, without the need for any code programming to complete a Bluetooth beacon. After the configuration is completed, the device power supply is running as a Bluetooth beacon, which will automatically collect sensor data and broadcast to the outside world according to the configuration information. It is suitable for IoT sensor nodes, such as smart farms, offices, factories, warehouses and other scenarios in the data collection node.

Adafruit SHARP Memory Display Breakout – 1.3″ 168×144 Monochrome
The 1.3″ 168×144 SHARP Memory LCD display is a cross between an eInk (e-Paper) display and an LCD. It has the ultra-low power usage of eInk and the fast-refresh rates of an LCD. This model has a gray background, and pixels show up as black-on-gray for a nice e-Reader type display. It does not have a backlight, but it is daylight readable. For dark/night reading you may need to illuminate the LCD area with external LEDs.
The bare display is 3 Volt powered and 3 Volt logic, so we placed it on a fully assembled & tested breakout board with a 3 Volt regulator and level shifting circuitry. Now you can use it safely with 3 Volt or 5 Volt power and logic. There are four mounting holes so you can easily attach it to a box.
The display is “Write Only” which means that it only needs 3 pins to send data. However, the downside of a write-only display is that the entire 168×144 bits must be buffered by the microcontroller driver. That means you cannot use this with an ATmega328 or ATmega32u4. You must use a high-RAM chip such as ATSAMD21, Teensy 3, ESP8266, ESP32, etc. On those chips, this display works great and looks wonderful.

EEPROM
EEPROM is a type of non-volatile memory. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.
RTC
A real-time clock (RTC) is an electronic device, most often in the form of an integrated circuit, that measures the passage of time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time of day.
Micro SD Card Breakout Board
If you have a project with any audio, video, graphics, data logging, etc in it, you’ll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. If you’re doing any sort of data logging, graphics or audio, you’ll need at least a megabyte of storage, and gigabytes. To get that kind of storage we’re going to use the same type that’s in every digital camera and mp3 player: flash cards. Often called microSD cards, they can pack gigabytes into a space smaller than a coin. They’re also available in every electronics shop so you can easily get more and best of all, many computers have microSD card readers built in so you can move data back.

Temperature Humidity Relationship
Temperature is something that tells us about the coldness or warmness of any object which is generally measured in Celsius. It determines the intensity of the heat whereas if we talk about humidity, it talks about the water content that is present in the air, or simply we can say it determines the moisture of the air. These two concepts are different but show a great impact on each other. We will see the relation between temperature and humidity further below. Before that, let’s understand more about humidity and its types.
Absolute Humidity and Relative Humidity
There are generally two types of humidity ie. absolute and relative. The former tells the humidity present in a parcel of air without taking temperature into consideration whereas the latter tells the humidity present in the air concerning the temperature of the air. The former defines the amount of water content by dividing the weight of the parcel by its volume whereas the latter is calculated by dividing the amount of water content present divided by the total capacity of the parcel of the air to hold multiplied by 100. The former decreases with height whereas the latter when reaching 100%, the air gets saturated.
Relation Between Relative Humidity and Temperature
We have already learned what is temperature and what is humidity and we have also learned two types of humidity. As we know, both these two concepts ie. Temperature and Humidity are different but they are related to each other. The relation between humidity and temperature formula simply says they are inversely proportional. If temperature increases it will lead to a decrease in relative humidity, thus the air will become drier whereas when temperature decreases, the air will become wet means the relative humidity will increase.

Smoke
Smoke is a suspension of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires, but may also be used for pest control, communication, defensive and offensive capabilities in the military, cooking, or smoking. It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative.
Smoke inhalation is the primary cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage, poisoning and pulmonary irritation caused by carbon monoxide, hydrogen cyanide and other combustion products. Smoke is an aerosol of solid particles and liquid droplets that are close to the ideal range of sizes for Mie scattering of visible light.
