KY-028 Digital Temperature Sensor Module with LM393 | Robochacha Pakistan

Makers choose the KY-028 Digital Temperature Sensor Module when they need a sensor that can think for itself. Specifically, the module uses a high-sensitivity thermistor to track ambient heat. As a result, when the temperature hits a certain limit, the onboard LM393 comparator flips the digital output to HIGH. Therefore, you can use it to build emergency shut-off systems without writing complex code. Furthermore, the module provides a dual-output system: a digital trigger signal and a raw analog voltage for precise logging.

Additionally, this module features an integrated potentiometer. Consequently, you can manually adjust the sensitivity to set exactly at what degree the digital alarm should trigger. Because of this, the KY-028 Digital Temperature Sensor Module remains the most reliable thermal switch for robotics and cooling systems in Pakistan.

Key Features

• Dual Output Mode: The board offers both Digital (D0) and Analog (A0) pins. Specifically, this allows for simple binary alerts or continuous monitoring of temperature fluctuations.

• Onboard Potentiometer: You can fine-tune the switching threshold. Therefore, you have full control over when your cooling fan or heater turns on.

• LM393 Comparator IC: This chip ensures a clean, stable digital signal. Consequently, your microcontroller wont receive false triggers caused by minor electrical noise.

• Standard 4-Pin Layout: This KY-028 Digital Temperature Sensor Module uses a clear G-V-D-A interface. As a result, it is easy to wire up to any Arduino, ESP32, or Raspberry Pi.

• Visual Status LEDs: In addition, the board includes a power indicator and a signal trigger light. Specifically, this makes it incredibly easy to calibrate your thermostat without using a serial monitor.
