PlatformIO project within Visual Studio.
- Esp8266 01
- DHT22
You need make modify for DeepSleep mode. It is necessary for correct working and long term battery live. Yellow wire. For circuit power source you need 3.3V. 2x1.5V is not enought. I use 18650 LiIon battery.
Before first run you must modify src/Config.h
for:
- Wifi
- ThingSpeak settings
- Depp sleep mode time
ThingSpeakWithoutDHT22 = true
if you want try Esp8266 without DHT22
