This module contains a NTC thermistor, which can measure temperatures in the range of -55 °C up to +125 °C. The resistance value decreases at higher temperatures. This has a lower resistance value at higher temperatures. Based on the resulting resistance curve, the corresponding temperature can be calculated.

The module is based on the thermistor (resistance increases with the ambient temperature changes) works, a sense of real-time to know the temperature of the surrounding environment changes, we send the data to the Arduino analog IO, then come down as long as we go through simple programming will be able to convert the sensor output data Celsius temperature values and displayed, it is still easy to use, It effectively, thereby widely used in gardening, home alarm systems and other devices.

The KY-013 Analog Temperature Sensor module consist of a NTC thermistor and a 10 kΩ resistor. The resistance of the thermistor varies with surrounding temperature, we’ll use the Steinhart–Hart equation to derive precise temperature of the thermistor.

Specification:

• Operates on 3.3V or 5V
• Fast response to temperature changes
• Dimensions: 20(W) x 15(L) x 5(H)mm
• Temperature measurement range:-55°C to 125°C [-67°F to 257°F]
• Measurement Accuracy: ±0.5°C

Application:

And the general temperature sensor is the same, are three-line package, when we use the power cord connected OK signal output into the end on the line, because the module output is an analog signal, we want to signal output terminal connected to the Arduino analog IO on sampling, so as to correctly read the temperature value.
