I bought a couple of these ESP32 Devkit V1 boards.
Have got one operating in Cayenne, I’ve made a dashboard to observe.
This link will get you to it.
Its just a basic;
Temperature, Humidity using DHT11
Pressure using a BMP085 that has bug that occurs when the environment gets to cold.
Room Light level is just an LDR.
The counter just counts the number of transmissions since turn-on.
The Packet Intervals is the time between transmission data bursts.
I have my own personal dashboard with some LED controls and servo control sliders on it.
I might put a LED control button on it, just to see who wants to play.
I have it here at home and I take it to work and plug it back in so the data will not always be continuous.
