OverviewThe SGP40 Air Quality Sensor (SparkFun) provides a measurement of the quality of the air in your room or house. The SGP40 is based on Sensirion's CMOSens® technology and uses a metal oxide (MOx) sensor with a temperature controlled micro hotplate and provides a humidity-compensated volatil..
OverviewThe Qwiic Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large, exposed pads function as probes for the sensor, together acting as a variable resistor. The more water tha..
The Qwiic MicroPressure Sensor is a miniature breakout equipped with Honeywell's 25psi piezoresistive silicon pressure sensor. This MicroPressure Sensor offers a calibrated and compensated pressure sensing range of 60mbar to 2.5bar, easy to read 24 bit digital I2C output, and can be calibrated and c..
Bosch's BMP388 is a blazingly fast, temperature stable, pinpoint accurate barometric pressure sensor specifically suited for altitude tracking in drone applications. We thought that sounded pretty cool, so we put it on a Qwiic-compatible breakout board to make it easier to prototype with. Simply con..
Whether you're an agriculturalist, a professional meteorologist or a weather hobbyist, building your own weather station can be a really rewarding project. When you're measuring weather, however, you need some pretty specialized sensors. This kit represents the three core components of weather measu..
--The SparkFun Lightning Detector adds lightning detection to your next weather station to make sure you are aware of any potential hazardous weather heading your way. The AS3935 is capable of detecting lightning up to 40km away with an accuracy of 1km to the storm front with a sensitive ante..

The SparkFun BME280 Atmospheric Sensor Breakout is the easy way to measure barometric pressure, humidity, and temperature readings all without taking up too much space. Basically, anything about atmospheric conditions find out from this tiny breakout. The BME280 Breakout has been design to be used ..
The SCD30 from Sensirion is a high quality Nondispersive Infrared (NDIR) based COâ‚‚ sensor capable of detecting 400 to 10000ppm with an accuracy of ±(30ppm+3%). In order to improve accuracy the SCD30 has temperature and humidity sensing built-in, as well as commands to set the current altitude. For..
SparkFun weather:bit is a fully loaded “carrier” board for the micro:bit that, when combined with the micro:bit, provides you with a fully functional weather station. With the weather:bit you will have access to barometric pressure, relative humidity and temperature readings. There are also connecti..
The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants or sensory irritants and can come from a variety of..
Humidity Temperature Sensor DHT22 is a calibrated digital temperature and humidity module with onboard sensor DHT22 (AM2302), which features higher accuracy and wider measuring range than DHT11. It can be used for detecting ambient temperature and humidity, through the standard single-wire interface..
The raindrop sensor module is used for rain detection. It is also for measuring rainfall intensity. The module includes a rain board and a control board that are separate for more convenience. It has a power indicator LED and an adjustable sensitivity though a potentiometer. The module is based on t..
Soil hygrometer humidity detection module is used to detect moisture. This is very sensitive to the ambient humidity. When the soil is dry the module outputs a high level, otherwise outputs low. This sensor can be used to make automatic watering system, so that garden plants can be watered without ..
