KY-028 Digital Temperature Sensor Module

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.

 

Operating Voltage 3.3V to 5.5V
Temperature measurement range -55°C to 125°C [-67°F to 257°F]
Measurement Accuracy ±0.5°C
