I’m trying OpenSprinkler using Paolo Becchi’s ESP32 implementation (on a little ESP32 LoRa board). It runs fine over the web, etc, though not connected to any sensors or valves… Currently waiting for a couple of his Smart Solenoids to try the LoRa portion!
Looking to hook up a reed switch flow sensor I bought recently, and thinking about how to connect it to the appropriate GPIO pin.
Imagining something like pull-up and pull-down resistors to Gnd and +3.3V, respectively. I thought to use the reference OpenSprinkler implementation as a guide to check my thinking. However, I can’t find a schematic to review, other than Eagle files on Github… does anyone have a PDF, or know how the flow sensor is actually wired to the GPIO pins on the board?
Any thoughts appreciated.
