PH2.0 3Pin DHT11 Sensor Module

PH2.0 3Pin DHT11 Sensor Module

The DHT11 digital temperature-humidity sensor is a composite sensor with a calibrated digital signal output. It utilizes specialized digital data acquisition and humidity-temperature sensor technology to ensure high reliability and excellent long-term stability. The sensor consists of a resistive humidity element and an NTC temperature measurement element.

The DHT11 communicates with a microprocessor via a single bus. It requires only a single thread, transmitting 40 data points at a time. The data format is: 8-bit humidity integer + 8-bit humidity decimal + 8-bit temperature integer + 8-bit temperature decimal + 8-bit parity. The data transmission process is as follows: the master sends a start signal -> the DHT responds -> the DHT notifies the master that it is ready to receive signals -> the DHT sends its data -> the DHT signals an end -> the DHT internally retests the ambient temperature and humidity and records the next data point.
