ESP32 with DHT11/DHT22 Temperature and Humidity Sensor ...

The DHT22 sensor has a better resolution and a wider temperature and humidity measurement range. However, it is a bit more expensive, and you can only request readings with 2 seconds interval. The DHT11 has a smaller range and it’s less accurate. However, you can request sensor readings every second. It’s also a bit cheaper.


DHT11 Humidity and Temperature Sensor

2) Response 3) Data Reading 1) Request: To make the DHT11 to send you the sensor readings you have to send it a request. The request is, to pull down the bus for more than 18ms in order to give DHT time to understand it and then pull it up for 40uS. 2) Response: What comes after the request is the DHT11 response. This is an automatic reply
