This product requires the user to burn the download program himself, and the problem is caused by burn-in damage, etc, please pay attention to beginners. This module is mainly controlled by ESP8266-01/ESP-01S, and DHT11 is a temperature and humidity sensor. The temperature and humidity in the ESP8266 acquisition environment are uploaded to the server. Support 3.7v-12V DC power supply (3.7V lithium battery). Can be used as a temperature and humidity collection node for smart home or IOT projects.
