WebHow DHT11 works The DHT-11 sensor uses a one-wire protocol to communicate the humidity and temperature values. The sensor act as a slave to a host controller. The digital communication between the DHT11 and the host controller (like Arduino) can be breakdown into four steps: 1. Start signal. WebIf you disconnect it briefly from current and reconnect it, it works perfectly. My solution was to put it on GPIO0. Also I found that a current of 3.3V is working fine, but it has to come from a stable source. The power supply module Power MB V2 from Elegoo did not work for me, even if put to 5V.
