Sensors

Sensors for physical quantities: temperature (DS18B20, NTC, K-type thermocouples, PT100), humidity (DHT11, DHT22, AM2302, SHT3x), pressure (BMP280, MPX), motion (PIR, microwave), Hall-effect, current (ACS712, ZMCT103), gas (MQ-2, MQ-7, MQ-135), light, and sound. Filter by measured quantity, range, accuracy, and interface (analog, I2C, 1-Wire, SPI). Used in smart home systems, weather stations, alarm systems, industrial automation, Arduino/ESP32 projects, and climate monitoring.
