A fast and precise environmental sensor that can measure temperature, pressure, and altitude. Our BMP280 breakout is Raspberry-Pi and Arduino-compatible. If you're looking for a simple temperature and pressure sensor, then this is the one to pick. It's...

Measure indoor air quality—total volatile organic compounds (TVOC) and equivalent CO2 (eCO2)—with this digital sensor for Raspberry Pi and Arduino. The SGP30 sensor measures two different types of gases: volatile organic compounds (like...

PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained -...

OCTOPUS PIR Sensor module is a type of electronic building block based on AM412 pyroelectric digital smart sensor. It can be used in sensing and detection of human or animal motion, sensing distance is about 4-5 meters. Dimension Specification Power...

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...

Instructions for Use Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil...

This switch at rest is open (off) state. When subject to an external force touch with a appropriate shaking force, or its movement speed reaches appropriate centrifugal force (eccentric) heart, conductive pins will be in instantaneous conduction state to...

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well made anemometer is designed to sit outside and measure wind speed with ease. To use, connect the black wire to power and signal ground, the...

The SparkFun 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...

The long awaited BME680 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities...

This straight bar load cell (sometimes called a strain gauge) can translate up to 5kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain...

This alcohol gas sensor detects the concentration of alcohol gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 0.04 mg/L to 4 mg/L is suitable for breathalysers (the legal limit of breath alcohol...

This breakout board is the simplest way to create a project with a single "momentary" capacitive touch sensor. No microcontroller is required here - just power with 1.8 to 5.5VDC and touch the pad to activate the sensor. When a capacitive load is...

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for any microcontroller. To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It...
