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.

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.

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.

Gravity: Analog Soil Moisture Sensor
A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It’s an ideal for monitoring an urban garden, or your pet plant’s water level. This is a must have component for a IOT Garden / Agriculture. The new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation. Electroless nickel immersion gold has several advantages over more conventional surface platings such as HASL, including excellent surface planarity, good oxidation resistance, and usability for untreated contact surfaces such as membrane switches and contact points.
This Soil Moisture Sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily, while dry soil conducts electricity poorly. This sensor will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.

Fermion: BLE Sensor Beacon
BLE Beacon, also known as Low Energy Bluetooth Beacon, is a small wireless device that broadcasts signals using BLE technology. Due to its broadcast nature, pairing is not required between the beacon and receiving devices. Each beacon contains a unique identifier, detectable by nearby devices equipped with Bluetooth technology, such as ESP32 and smartphones supporting BLE scanning.
This Bluetooth beacon has a built-in 11-bit ADC, Fermion version, and multiple I/Os that can be multiplexed to SDA/SCL while broadcasting over Bluetooth. Users can access sensor data within broadcast range on a Bluetooth-equipped device such as a Smartphone or ESP32. This BLE beacon has a built-in 11-bit ADC and an I2C interface, allowing it to real-time collect and broadcast data from various types of sensors, including analog, digital, and I2C sensors.

SparkFun Triple Axis Accelerometer Breakout – MMA7361
This is a breakout board for Freescale’s MMA7361L three-axis analog MEMS accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.
This breadboard friendly board breaks out every pin of the MMA7361L to a 9-pin, 0.1″ pitch header. The sensor works on power between 2.2 and 3.6VDC (3.3 Volt optimal), and typically consumes just 400µA of current. All three axes have their own analog output.
- Two selectable measuring ranges (±1.5g, ±6g)
- Breadboard friendly – 0.1″ pitch header
- Low current consumption: 400 µA
- Sleep mode: 3 µA
- Low voltage operation: 2.2 Volt – 3.6 Volt
- High sensitivity (800 mV/g at 1.5g)
- Fast turn on time (0.5 ms enable response time)
- Self test for freefall detect diagnosis
- 0g-Detect for freefall protection
- Signal conditioning with low pass filter
- Robust design, high shocks survivability
