All things pertaining to wireless and RF links
By jrowell
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 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!
