Keyestudio Analog Temperature Sensor Compatible with Arduino

This module is based on the working principle of a thermistor (resistance varies with temperature change in the environment). It can sense temperature change in its surrounding and send the data to the analog IO in the Arduino board. All we need to do is to convert the sensor output data into degrees Celsius temperature via simple programming, finally to display it. It's both convenient and effective, thus it is widely applied in gardening, home alarm system and other devices.
