KY-013 analogue NTC temperature sensor

Check the module’s supply and output voltage against the controller’s input limits before connecting it. A 5V supply does not make the signal safe for a 3.3V GPIO or ADC; use suitable level/voltage conversion. Analogue signals require an ADC, which a standard Raspberry Pi computer does not include.

KY-013 combines an NTC thermistor with a simple, effective voltage divider.

The NTC thermistor's resistance decreases as temperature rises.

Despite the thermistor's nonlinear response, temperature can be calculated using the Steinhart–Hart equation or a lookup table. The NTC resistance decreases as temperature rises. The sensor provides an analogue voltage that must be read with an ADC and converted to temperature. It can be used with Arduino or Raspberry Pi.

KY-013 temperature sensor is useful for temperature-dependent signalling. Its compact size and simple connections make it easy to integrate into electronic circuits; converting its voltage to a temperature requires calculation or calibration.
Putting the NTC thermistor in series with an ordinary resistor produces a temperature-dependent voltage at their junction.
