Description
KY-028 module is ideally suited to adding temperature sensing to your project and is compatible with microcontrollers such as the Arduino and Raspberry Pi.
The digital signal pin outputs HIGH when the level goes above the trigger level and LOW when below it, trigger level can be adjusted via the onboard potentiometer.
A power LED is mounted on the board as well as an indicator LED that lights when the sensor is detecting above the trigger level.
