Feature: 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.
Characteristic:
Master: ESP-01/ESP-01S (This module does not include ESP-01/ESP-01S)
Temperature and humidity sensor: DHT11
Working voltage: DC 3.7V-12V (supports 3.7v lithium battery power supply)
For real world battery-powered usage this won't work well because it wastes a lot of power on the LED and the voltage regulator. I removed the LED (-4mAh), and will eventually just desolder the DHT and wire it directly to the ESP-01 (I don't need the regulator).
Excellent for prototyping, but not beyond.
