PH and Temperature Hydroponic Monitor using MQTT
There have been quite a few requests for the code for my MQTT posting IOT project for testing PH and Temperature of my hydroponic towers. This code is several years old and I haven’t looked at it for at least 2. But, I figured I would put it out on GitHub.
The main purpose of this code is to monitor the PH and temperature in a water tank for my hydroponics and then use MQTT to post to io.adafruit for a dashboard.
