Environmental sensors measure the physical and chemical properties of the surrounding atmosphere and soil, providing the data needed for weather monitoring, air quality assessment, agricultural automation, and climate-responsive IoT systems.
The range includes DHT11, DHT22, and BME280 temperature and humidity sensors, MQ-series gas sensors for CO, smoke, LPG, and VOC detection, anemometers and wind direction sensors, and capacitive and resistive soil moisture probes.
These sensors are used in Arduino and ESP32 weather stations, greenhouse automation systems, indoor air quality monitors, smart agriculture and hydroponics builds, school science projects measuring climate variables, and any IoT deployment where environmental data is the core output.
