SensESP Optocoupler Current Detector

[dagnum]

Prototype was using basic ESP32 Optocoupler from these Boards from Amazon for 16 channels:

Then I worked with a engineer to design a custom Optocoupler PCB that only has 11 channels but super compact and designed for the Seeed S3 ESP32.

Currently, I am using it to detect if Sump and Bilge pumps are 1. Powered 2. Active. For Example, if the Bilge Pump is not powered then i use raspberry pi to send SMS to send alerts, same for if the Bilge is Active.

If anyone is interested I can post the pcb, sensesp platformio files, nodered config etc...
