KY-028 4 Pin Digital NTC Thermistor Temperature Sensor Module is a sensor that uses NTC temperature resistance.
The purpose is not to show the ambient temperature. NTC sensors produce On and Off (0/1) according to the temperature value we set.
One of the common uses is to ensure that fans that provide cooling of electronic circuits that produce high heat, such as power supplies, operate when the specified frequency is exceeded. The resistance value decreases as the NTC resistance on it heats up.
The temperature sensitivity is changed with the trimpot on this sensor module and the required temperature value is determined.
This KY-028 NTC Thermistor Sensor Module can measure temperatures in the range of -55°C up to +125°C. This has a decreasing resistance value at higher temperature. 4 pin ntc thermistor temperature sensor module is a kind of resistor with a Negative Temperature Coefficient.
NTC temp sensor module KY-028 has three functional components on its circuit board. One is the sensor unit at the front of the module, which physically measures the current environment and outputs it as an analog signal to the second unit, the amplifier. This amplifies the signal depending on the resistance set on the rotary potentiometer and sends it to the analog output of the module.
thermistor temperature sensor module has a digital interface, built-in 13 LED build a simple circuit, making the temperature warning lamp 13 comes with digital interfaces of the LED, the digital temperature sensor connected digital three interfaces, when the digital temperature sensor senses a key signal, LED lights, otherwise off.
Generally, the 4 wire method of thermistor measurement is the most accurate because there is effectively no current flowing in either of the measurement cable wires and therefore no added resistance due to the cable wires.
