description 1 3 Pinout 2 4 Functionality of the sensor 2 5 Code example Arduino 3 6 Code example Raspberry Pi 4 Picture Technical data / Short description Temperature measurement range: -55°C / +125°C This module includes a NTC Thermistor - its resistance falls with higher temperature. Digital Out: While measuring a temperature which is higher than the limit value, it will be shown here - you can set the limit value via potentiometer  Analog Out: Direct measurement of the sensor unit LED1: Shows that the sensor is receiving power LED2: Shows that a magnetic field was detected Export: 16.06.2017 Copyright by Joy-IT - Published under CC BY-NC-SA 3.0 Page 128 of 214 KY-028 Temperature Sensor module (Thermistor) Pinout Functionality of the sensor The sensor has 3 main ponents on its circuit board. First, the sensor unit at the front of the module which measures the area physically and sends an analog signal to the second unit, the amplifier. The amplifier amplifies the signal, according to the resistant value of the potentiometer, and sends the signal to the analog output of the module. The third ponent is a parator which switches the digital out and the LED if the signal falls under a specific value. You can control the sensitivity by adjusting the potentiometer. Please notice: The signal will...
