Stainless Steel Case for PT100 DS18B20 Temprature Sensors - 6x50mm Previous 
KY-028 Digital Temperature Sensor Module is a temperature sensing module for ambient temperature measurement. It uses an NTC thermistor whose resistance decreases as temperature increases. The module provides both analog and digital outputs for electronic projects. A potentiometer on the board allows threshold adjustment. The digital signal is suitable for direct connection to a microcontroller.
Features of KY-028 Digital Temperature Sensor Module
- Analog and digital outputs
- Adjustable temperature threshold
- NTC thermistor sensing
- Direct microcontroller output
Specifications of KY-028 Digital Temperature Sensor Module
- Temperature measurement range: -55°C to +125°C
- Temperature detection range: 20 to 80 degrees Celsius
- Output: digital and analog
- Dimensions: 30x15x5 millimeters
- Weight: 5 grams
- Supply voltage: 3.3 to 5 volts DC
How to Use KY-028 Digital Temperature Sensor Module
- Adjust the potentiometer to set the temperature threshold.
- Connect the DO output to a microcontroller input if digital detection is needed.
- Monitor the analog or digital output according to the application.
More Info
- LED1 indicates that power is connected to the module.
- LED2 indicates that the temperature has passed the threshold.
