I require a very simple product that has both a transmitter and a receiver. This will be used to wirelessly extend an irrigation system.
When the Irrigation System starts a watering program it outputs 24V to the terminals which then powers a solenoid to water the lawn. At the end of the program the power is stopped and the solenoid is closed.
The transmitter will be connected to those terminals to receive the 24V power on start of program. This will trigger a signal to be transmitted to the receiver that will then trigger a relay. The required power for the solenoid will be connected to the relay. The relay will need to be capable or 5v to 240v.
The receiver will need external power - 24v
I will also require the Tx and Rx to be assignable as pairs (max 99 pairs required).
This Tx and Rx need to ultimately be produced as cheaply as possible.
I would also like a prototype to be supplied.
Distance should be no less than 70m.
Hello, I'd like to help you with the project. Could you write what distance should cover this wireless extender? The production price will be vary from this. I can use 433MHz transmitter - receiver pair or 2.4GHz tran Plus
