Dht11 Temperature and Humidity Sensor Module Digital Switch

The DHT11 Temperature and Humidity Sensor Module is a reliable and cost-effective sensor designed for accurate measurement of ambient temperature and relative humidity. It provides digital output signals that are easy to read using Arduino, ESP32, Raspberry Pi, and other microcontrollers. Built using advanced digital signal acquisition and sensing technology, the DHT11 integrates a resistive humidity sensor, an NTC temperature sensor, and an onboard 8-bit microcontroller for signal processing and calibration. Each sensor is individually factory-calibrated in a precision humidity calibration chamber, ensuring consistent and accurate readings. Calibration coefficients are stored in internal OTP memory for use during operation, guaranteeing long-term reliability and high stability.
