How to make simple wireless switch?
Posted: Wed Jun 14, 2017 11:52 pm
I would like to make a wireless switch to control a water pump. There would be a transmitter connected to a float switch in the water tank, and a receiver to control a well pump a few hundred feet/meters away. I have seen solutions such as https://www.adafruit.com/product/1096 but they use a handheld fob transmitter and the range is too short. Where can I find a transmitter that is on a circuit board instead of a handheld fob? Thanks!
