Moisture and Temperature Sensor

Yet another loop powered Timer circuit used to send 3mA or 10 mA over a CAT5 pair. This time, I have used a separate CAT5 pair as the capacitive sensor. I have doubts about how useful it will be, the capacitance changes significantly with temperature, which I can see in the video when I use the heat gun. Though I am fairly confident that this can be used to find the thermistor value.
