[KY-013] | Temperature sensor module | ![]() |
This code don't give the right values, in a room that was kind of ok it gave a tempature of 10 C. That isn't right so the calculation in the code should be checked. Temperature sensor module KY-013 These modules are the same, they're all on boards labelled "S1". THE PINS ARE MARKED BACKWARDS ON THESE. Has pin 1 (marked S) (GND), pin 2 (5v power) and pin 3 (marked -) (analog signal.)?? | Temperature sensor module Temperature sensor module |
