KY-028 Digital Thermistor Temperature Sensor Module
KY-028 overview
The KY-028 is a Digital Thermistor Temperature Sensor Module. Main ratings: The output format Digital switching output (0 and 1); Small board PCB size 3.2cm x 1.4cm. This page brings together the KY-028 pinout and key specifications, with the full datasheet PDF to preview below or download.
KY-028 NTC Thermistor 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. KY-028 NTC Thermistor Sensor Module can be used in various circuits using this feature.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 temperatures. An NTC Thermistor is a kind of resistor with a Negative Temperature Coefficient. KY-028 NTC Thermistor Sensor Module 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.
