KY-028 Digital NTC Thermistor Temperature Sensor

The KY-028 is a Digital NTC Thermistor Temperature Sensor which is a small, easy-to-use module that can be used to measure temperatures in the range of -55°C to 125°C. It has both digital and analog outputs, and a potentiometer to adjust the detection threshold on the digital interface.

The module consists of an NTC thermistor, an LM393 dual differential comparator, a 3296W trimmer potentiometer, 6 resistors, 2 LEDs, and 4 male header pins. The NTC thermistor is a type of resistor whose resistance decreases with increasing temperature. The LM393 comparator compares the resistance of the thermistor to a reference voltage, and outputs a digital signal if the temperature exceeds a certain threshold. The potentiometer is used to adjust the threshold temperature.

The KY-028 module is compatible with a wide range of microcontrollers, including Arduino, Raspberry Pi, and ESP32. It can be used in a variety of applications, such as temperature monitoring, thermostat control, and home automation.

The KY-028 Digital Thermistor Temperature Sensor Module can operate with an input voltage of 3.3V to 5.5V. This means that it can be powered by a wide range of sources, including a USB port, a battery, or a regulated power supply.

The 4PIN Thermistor Temperature Sensor Module is compatible with a wide range of microcontrollers, including Arduino, Raspberry Pi, and ESP32. 

KY-028 Temperature Sensor Module has both digital and analog outputs. The digital output is a logic level signal that is either HIGH or LOW, depending on whether the temperature is above or below the threshold. The analog output is a voltage signal that is proportional to the temperature.

If you are looking for a simple, easy-to-use temperature sensor module, the 4PIN Thermistor Temperature Sensor Module is a great option. 

Features : –

The NTC thermistor in the KY-028 module is connected to an LM393 comparator. The LM393 comparator compares the resistance of the thermistor to a reference voltage. If the resistance of the thermistor is lower than the reference voltage, the LM393 comparator outputs a digital signal. The digital signal can use to control other devices, such as LEDs or buzzers.
