This module uses ESP8266-01/ESP-01 S (without ESP-01 S or ESP-01) as the master control, and DHT11 as temperature and humidity sensor. ESP8266 collects the temperature and humidity in the environment and uploads to the server. It supports 3.7v-12V DC power supply (3.7V lithium battery). It can be used as temperature and humidity collection node for smart home or IOT project.
