Projects General Guidance
1

I am looking to Send a Digital Output signal Either (5 or 24VDC) from my PLC to a wireless transmitter and then a receiver it 100m away, it will be just a digital on/off signal to turn on my boar pump..

i all ready have all the control wiring for the boar pump. just need to switch a 24v circuit on for the relay which will turn the boar on.

so i want to send a Digital ON/OFF output via wireless to a receiver which will then turn a relay on/off.

can you please guide me in the best way to achieve this ?? and what material i would need thanks also upload a little sketch to help

You need 2 ESP modules, and a circuit to interface them with your hardware, as well as code to deal with the communication.
