Digital Temperature Sensor Module KY-028

The KY-028 digital temperature sensor unit is a unit used to measure temperature and provide a digital output when a certain threshold is exceeded. It is suitable for alarm applications when the temperature rises or falls or for simple control systems. The unit relies on a thermistor to measure heat and a voltage comparator. It provides an analog output reflecting the temperature, and a digital output that can be adjusted using the built-in voltage meter. Technical details: Unit model: KY-028 Operating voltage: 3.3 volts to 5 volts Output type: digital and analog Temperature measurement range: -55°C to +125°C
