Would like to create an RF switch that connected to 24 volt battery and the switch is activated by current flow. Also need to create a receiver for this switch that will turn on line voltage item
have a read of how-to-get-the-best-out-of-this-forum
e.g.
- does the area have WiFi coverage?
- what is the distance between transmitter and receiver?
what microcontroller are you using?
Thanks for reply. I have no knowledge of electronics complete novice. I want to see if possible to turn battery driven tool and when current flows it would send a RF signal to receiver that would turn light on only when current is flowing wifi not available. Distance under 50 feet
you could use a couple of ESP32 modules using the ESP-NOW protocol
also have a look at acs712-current-sensor-and-arduino-a-complete-guide
