Description

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
