Ph sensor

Dose anyone know if terrariumpi 4.2 suports this probe sensor?

Hmm, I have not tested Ph sensors. There should be 1 working. https://theyosh.github.io/TerrariumPI/hardware/sensor/sen0161-ph-probe-sensor-analog/ And that is using: https://theyosh.github.io/TerrariumPI/hardware/#analog-sensors

So I guess that you need at least a https://rasp.io/analogzero/ to connect the sensor to the Pi. This will take some GPIO space...

But there are more ways. You could also use an Arduino to readout the Ph sensor, provide a web server on the Arduino so TP4 can read it out using it as a remote sensor.

Or if you are a bit handy and have some programming skills, make you own script/code to do a readout of the sensor. This can be done in many ways. But when you have a script, you could also use that as a sensor source, to get the Ph sensor readout.

Sorry to not have a clear answer, but this is an analog sensor, which is never directly supported by TP4

Sorry for extremely late response. Thank you for the answer. It was wery useful. So when I connect the sensor to the software i can select read out from script and import my script. I have ordered the sensor and adc chip but unfortunately it will take a couple of months before I get it. I will tell you if it work or I'll post the script here if it will be necessary.

Yeah, I think making your own code for the readout would the easiest way for analog sensors. So, if you have that working, I can help to get it in TP4.
