WeMos Relay
thingiverse
This is a series of different sensors based on a WeMos D1 Mini, which has an ESP8266, with the aim of sending measurements in real time to an MQTT server and, through a NodeRed server, to be able to have a visualization in real time. actual sensor measurements (temperature, humidity, eCO2, TVOC, etc.) In this case it is not a sensor but the WeMos relay shield. With it we could activate or deactivate, for example, a lamp, an extractor, a heater or a liquid valve. In my personal case, I used it to activate a heater to heat my house depending on the temperature value given by the DHT22. To assemble it, you will need 4 DIN7505B 4.5x25 screws, or similar. I hope you enjoy it!
