Re: People Hi ! from Medoc, France.

Hi JiM, I tutor an after-school IoT Computer Club here in the UK. One of my students has just started a project to build a solar-powered soil moisture sensing and weather station. The plan is to use a Wemos D1 Mini (ESP8266-based device) running ESP Easy that reads the various sensors and sends the ...
