MicroPython Vegetable Garden Automation Tutorial #MicroPython #ESP32

Rototron highlights a project which adds solar powered sensors and home automation to a vegetable garden and transmits the data using MQTT for review and control on a mobile app.

An ESP32 running MicroPython will be used to poll the controller for voltage and current levels.  A step down regulator will drop the 12 VDC output of the controller down to 5 V to power the ESP32 via its micro USB jack.  The 3.3 V TTL communication lines from the MPPT charge controller are connected to the ESP32’s serial port.
