The KY-028 is a temperature sensor module that can be used to measure the ambient temperature. It consists of a thermistor and a small circuit board that can be used to convert the resistance of the thermistor into a temperature reading. The module can be used in both digital and analog mode. In digital mode, the module converts the temperature reading into a digital signal that can be read by a microcontroller or other device. In analog mode, the module outputs an analog voltage that is proportional to the temperature. The module can be used in a variety of applications, including temperature monitoring and temperature control. Use this 4-pin module to determine the heat as detected by the Thermistor. Perfect for Arduino projects 1. using the NTC thermistor sensor , good sensitivity 2. the comparator output signal clean waveform is good , driving ability, than 15mA. 3. adjust the temperature distribution bit detection threshold 4. Working voltage 3.3V-5V 5. the output format : Digital switching output (0 and 1) 6. with bolt holes for easy installation 7. a small board PCB size : 3.2cm x 1.4cm 8. using a wide voltage LM393 comparator
