I am integrating the PR33-15 with our ESP32 based edge architecture for robotics. I2C is fine, I’m happy accessing the readings in the device.
I was hoping to get some more information on best practices when connecting to a 2-wire passive analogue device - it is essentially a photodiode which outputs a microamp output or mV output with a resistor. I am hoping to read this value on the PR33-15 (well 2 signals on 2 channels actually) as we are calculating NDVI. The sensors are quite pricey, so definitely don’t want to damage them, by powering them or similar.
Attaching the documentation for the sensor - 2 CHANNEL LIGHT SENSOR-SKR 1840-DATASHEET.pdf (641.4 KB)
Anybody got helpful suggestions on how to go about this integration in a safe way?
