I have a project that needs one ESP8266 to send commands to another device. Specifically the master unit is attached a a lidar measuring the tree canopy in an orchard, attached to an orchard sprayer. If a gap is detected it needs to activate 4 relays on the slave board to turn off nozzles. In this way spray can be saved making the owner very happy. I'm imagining a string of numbers being sent to the slave with 0 representing off and 1 representing on. We have the Lidar and relays working but would prefer not to run cables down the length of the sprayer. Any thoughts on how i achieve this?
As an added bonus during development i would like a supervisor to be able to change the delay between sensing a gap and turning a nozzle on/off
