Wemos experiment

Power Node sensor with bme280, measures temperature, humidity, pressure and battery voltage. Sends measurements to gsm master node every 10 min. Current consumption ~ 10uA at 2.6V.

Internet of things wireless 220V plug module

Data from DHT22 sensor

Monitoring the outside temperature using a WiFi connection with a Wemos D1 microcontroller and a DHT22 sensor

It will show the temp, humidity, CO of my Smart Home
