Temperature sensor module

Model: KY-028.
Temperature sensor module.
The module allows temperature measurement through an NTC thermistor, in which the data conditioning process will allow the sensor to adapt an operable work signal. It consists of an NTC thermistor, an LM393 comparator, two indicator LEDs, a potentiometer.
Specifications:
Operating voltage: 3.3 V to 5 V.
Temperature measurement range: -55°C / +125°C.
Output type: analog and digital.
LED1: shows that the sensor is receiving power
LED2: shows that the temperature is within the comparator range.
Dimensions: 38 x 15 x 14 mm.
Weight: 3 g.
