Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4416174.

A small project box to house a Wemos D1 Mini and Soil Moisture sensor. I've added an extra hole for the cable of a DS18B20 temperature probe too.

Power is supplied via some CAT5 cable. The ESP8266 module is the Wemos D1 Mini V3 PCB, not the one with the ESP8266 in a can in the PCB.

I'm running Tasmota which in turn is sending the value to my MQTT server and on to Home Assistant.

FreeCAD model is included as always!

Enjoy...
