Περιγραφή
Digital Temperature Sensor KY-028 for Arduino, it measures temperature changes based on the thermistor resistance. This module has both digital and analog outputs, there’s a potentiometer to adjusts the detection threshold on the digital interface.
The KY-028 consist of a of a NTC thermistor, a LM393 dual differential comparator a 3296W trimmer potentiometer, six resistors and two indicator LEDs. The board features an analog and a digital output.
