Atmospheric Sensors
From just checking the weather, humidity or temperature, or looking for a new project, why not make an automatic watering system with a soil moisture sensor? Check how clean a room is with a dust or air quality sensor or maybe even a Carbon Monoxide detector. We have a wide range of sensors for detecting and measuring weather, air, gas and other atmospheric conditions.
