Y have one ESP8266-01 for testing, and my project is to make autonomous the sensor HD1008.
In this photo, my box with esp8266, two power 5v->3,3v (first for esp8266, and second for CH_PD and HD1008)
The DEL is for testing GPIO0 and GPIO2.

The code to send the data to my server works. It remains to be able to use the HD1008 sensor.

Everything will be solar-powered.
