this will be cool for water temp sensor, like the labview gauges in real time measuring
I am facing this common issue:
pipes and water inside the pipes are over heated due to sunlight exposure this water will kill the plants, the idea is to open the valve for some time until the water cools down looking at the gauge and let the program decide when to start watering plants, we could easily a temp sensor close to the water pipe to monitor its temp using the available UTM lines.
but it will require more modifications in the interface to make this more inteligent
what I do now is to water plants at night. at the morning, and if I will water at noon, introduce a open valve outside the pants area for some time using a dealy, until I feel that the water is cool enoght
