Being new, I'm working out the exercises in the book "arduino projects book".
On project 03, the temperature reads approx. 20°C @ 0.71V.
When I put my finger nearby or on the sensor, the temperature rises and after +2°C , the blue LED goes on.
But then the temperature rises quickly to 45°C, in no time, the other two LED's lighten up. Not being ill, this is pretty weird. And the temperature does not fall down again. It stays at 45°C.
Anyone tips on what I could / should do?
The sketch is exactly as in the book, the setup on the board is ok. Sensor is not turned around.
Should I calibrate the sensor? And how would that work. I found calibration with a light sensor and applied it, but no idea whether this worked.
Thanks
Stijn
