Hello.
I am designing a simple monitor that monitors a water storage tank. It basically consists of a tank with a float activated switch in which the switch is closed when the tank is full.
The system will check the level of the tank once every hour. If the tank is full, a transmitter will send a signal to a receiver located at another location. If the tank is not full, it will not send a signal.
I need the transmitter to be able to transmit for at least 3 miles. Further would be great. What are my options regarding transmitters and receivers?? The transmitter needs to be battery powered.
