Hi all,

I my project I have PT100 thermometer with operating temperature range -50 °C ...150 °C. This sensor will be connected to AM2 RTD module. How do I scale this to read actual temperature? Also when the temperature below 5 degrees - Q1 output is high.

 If anyone could help me to write a program or understand how to do it that would be very helpful.

Thank you in advance for any help ! :)

Hi

Thank you for your response.

I just need a bit of clarification. The PT100 thermometer I’m using has a temperature range of -50 °C to 150 °C. However, on the analog threshold trigger, the scale seems to go from -50 to 200. I'm a bit confused about how this maps to the actual temperature range of the sensor. Could you please help me understand how it reads the -50 to 150 °C range within this scale?

Thanks again for your support.
