You require a pullup resistor between the data wire and VCC because the DHT11 uses a bidirectional communication system on a single wire. When neither end is communicating both ends of the link will be in "high impedance" mode - i.e., input mode. In that case the signal will be "floating" and needs the pullup to keep it in a … WebJan 7, 2024 · DHT11 Sensor Working. The working of this DHT11 temperature and humidity sensor is very simple for all the models available in the market. As the data is given out via a single pin. So adequate delay must be given between retrieving two consecutive values. The 4th pin on the module is the NC pin, which is not connected … solid mahogany writing desk
