DHT11 Single-Wire Communication Protocol: Data Format and Implementation
Data Packet Structure
The DHT11 sensor uses a single-wire communication protocol. Each data transmission consists of a 5-byte packet organized as follows:
Byte 0: Integer part of humidity
Byte 1: Fractional part of humidity
Byte 2: Integer part of temperature
Byte 3: Fractional part of temperature
Byte 4: Checksum byte
The sensor transmits da ...
