Hi - I am using a PT1000 4 wire temperature sensor on a MAX31865 board - connected to a Raspberry Pi - running node red.
The node is installed - and I am able to get data - only it is wrong data..
When I connect the PT1000 sensor I get readings of 988.79 - and nothing changes if I heat up the sensor - If i remote some wires in the middle i get -242.02 -
So I guess that I have some kind of data - but the wrong kind 😉
I have tried 2 different MAX31865 boards no luck
I have 4300 resistans on the borad - and also set up in the node- for the PT1000 sensor
Does anyone have an idea?
