Measure the moisture level in soil using the SparkFun Soil Moisture Sensor. The two probes are inserted into dirt, sand or similar materials and the sensor returns an analog voltage signal based on the amount of conductivity due to the water in the soil. More Details...
Code: SEN-10059
DHT11 digital temperature and humidity sensor features low power consumption, temperature compensation and inbuilt microcontroller for accurate readings. Easy hookup using the included cable. More Details...
Code: SKU-000879
This waterproof digital temperature probe with a total length of 6 feet has a temperature range of -55°C to+125°C and uses 1-wire interface for communication. More Details...
Code: SEN-10079
The TMP36 is a simple to use temperature sensor with an analog voltage output that varies linearly with the ambient temperature. It reads from −40°C to +125°C and operates at 2.7V - 5.5V DC so is suitable for most microcontrollers or analog circuits. More Details...
Code: SKU-002200
This is a stainless steel, Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a ‘hot’ end and a ‘cold’ one). More Details...

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 specialised sensors. More Details...
Code: SKU-003928
The CCS811 is a sensor for detecting the level of carbon dioxide (CO2) and Total Volatile Organic Compounds (TVOCs) in the air. TVOC combined with CO2 is used to measure indoor air quality or IAQ. More Details...
Code: SKU-002710
Sparkfun’s carrier board for the HIH-4030 relative humidity (%RH) sensor from Honeywell outputs an analogue voltage that varies nearly linearly with humidity. It operates at 5 V while drawing only 200 μA and has a 0.1" pin spacing that makes it compatible with standard breadboards and perfboards. More Details...
