The KY-28 measures temperatures and relays information back to the microcontroller. The module has a built-in potentiometer to adjust the sensitivity. This module contains an NTC thermistor- it has a declining resistor value on a rising temperature.
- Measurement Range: -55 celsius to +125 Celsius;
- Analog output: direct measurement of the temperature sensor;
- Digital output: If the temperature is rising above a limit, its given out here. The limit can be controlled with the potentiometer;
