TMP36 Temperature Sensor Features The TMP36 sensor is used to measure temperature from -40°C to +125°C and its tolerance threshold is +150°C. This sensor is calibrated directly on Celsius and its accuracy is 2°C. This sensor has an analog output. The output voltage changes linearly as the temperature changew. For example, the sensor output voltage is 0.75 volts at 25°C and 2.7 volts at 125°C.This sensor can be used in environmental control systems, thermal protection, fire alarms, CPU thermal m...

Introduction The KY-028 module contains a thermistor sensor that measures the ambient temperature. The resistance of the thermistor varies inversely with temperature. In addition, the analog and digital output pins provide the sensor's data. When the value measured by the sensor exceeds the threshold, the digital pin goes HIGH, lighting up the LED on the module. Tip You can adjust the digital output threshold using the blue potentiometer on the module. KY-028 Pi...
