Question

sensor 2 outputs similiar reading to sensor 1

Opened this issue 3 years ago · 4 comments

Sensor 2 is outputting a similar reading to sensor 1, it also looks like when only 1 sensor is connected the reading is double what it should it be.

Needs further investigation.

Note: I haven't had the chance to try different thermistors, so the double reading could be an issue there.

Tested with new thermistors, issue lies with the thermistor, not the firmware/hardware. Closing.

I was wrong, issue seems to still be present - it's also registering a value in sensor 2 with nothing connected, I'm leaning towards hardware issue

factoring in the resistance of both sensors when fetching the rth seems to work for now, will investigate further and re-open if it should be solved in the hardware

re-opening, the sensor reading is now accurate but, value is identical
