WebOct 27, 2024 · The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). The temperature range of DHT11 is from 0 to 50 degrees Celsius with a 2-degree accuracy. WebJul 5, 2024 · The DHT11 protocol works over a 1-wire connection. This line is active high. To enable the DHT 11 sensor Send LOW for at least 18ms Release LOW Expect LOW for 80us Expect HIGH for 80us The sensor will then transmit a total amount of 40bit data by sending differently typed impulses over the wire: Bit 0: HIGH for 26-28us, followed by LOW for 50us population density map definition
