KY-013 Analog NTC Thermistor Temperature Sensor Module for Arduino
KY-013 Analog NTC Thermistor Temperature Sensor Module for Arduino
Buy the KY-013 Analog NTC Thermistor Temperature Sensor Module online in Pakistan from Robostan.pk. This compact analog temperature sensor is designed for Arduino, ESP32, Raspberry Pi projects with an external ADC, robotics, environmental monitoring, and DIY electronics applications.
The KY-013 Temperature Sensor uses a Negative Temperature Coefficient (NTC) thermistor to measure temperature changes. As temperature increases, the thermistor's resistance decreases, producing a change in the module's analog output voltage.
With its 10kΩ thermistor, three-pin interface, 3.3V to 5V operating voltage, and commonly specified -55°C to +125°C sensing range, the KY-013 is useful for learning analog temperature measurement and developing electronic temperature monitoring systems.

How Does the KY-013 Temperature Sensor Work?
The KY-013 NTC Temperature Sensor measures temperature using a thermistor whose resistance changes according to the surrounding temperature.
NTC stands for Negative Temperature Coefficient. This means that the thermistor resistance decreases as its temperature increases.
The module combines the thermistor with a fixed resistor to create a voltage divider. Changes in temperature affect the divider's output voltage.
A microcontroller reads this analog voltage through an ADC and converts it into a temperature value using the appropriate mathematical equation and thermistor parameters.
KY-013 Pinout
- S (Signal): Analog voltage output
- + (VCC): Positive supply, typically 3.3V or 5V
- - (GND): Ground connection
Note: The middle pin is VCC on commonly documented KY-013 modules. Verify the pin markings and actual PCB layout before connecting power.
Arduino Compatibility
The KY-013 is compatible with Arduino UNO, Arduino Nano, Arduino Mega, and other controllers featuring suitable analog input pins.
For a typical Arduino UNO connection:
- Connect KY-013 S to Arduino A0.
- Connect KY-013 + to Arduino 5V.
- Connect KY-013 - to Arduino GND.
The Arduino reads the sensor's changing analog voltage and converts the reading into a temperature value using the appropriate thermistor calculation.
ESP32 and Raspberry Pi Compatibility
The KY-013 can also be used in ESP32 temperature monitoring projects. When connected to an ESP32, power the module at a voltage compatible with the ESP32's analog input requirements.
For Raspberry Pi applications, an external analog-to-digital converter such as an ADS1115 or MCP3008 is required because standard Raspberry Pi GPIO pins do not provide analog inputs.
KY-013 vs Digital Temperature Sensors
The KY-013 differs from digital sensors such as the DS18B20 and DHT22.
- KY-013: Analog NTC thermistor module requiring ADC measurement and temperature calculation.
- DS18B20: Digital temperature sensor using a 1-Wire interface.
- DHT22: Digital temperature and humidity sensor.
The KY-013 is useful for applications where a simple analog temperature signal is preferred.
Why Choose KY-013?
Simple Interface: Connects to compatible microcontrollers using a single analog signal.
Compact Design: Suitable for small electronics projects and embedded systems.
Temperature Monitoring: Useful for educational environmental and electronics experiments.
Flexible Integration: Works with multiple controller platforms when the required ADC is available.
Educational Value: Helps demonstrate voltage dividers, NTC resistance characteristics, analog conversion, and temperature calculations.
Important Usage Notes
- The KY-013 provides an analog output, not a digital temperature reading.
- Correct temperature conversion requires the proper NTC resistance and B-value.
- Sensor accuracy depends on component tolerances, calibration and operating conditions.
- The full advertised temperature range should be verified for the actual thermistor and PCB.
- Do not connect a 5V analog output directly to a 3.3V-only ADC input.
- Raspberry Pi projects require an external ADC.
- The module is not waterproof or intended for liquid immersion.
- Avoid using it near high temperatures that could damage the PCB.
- Allow time for the thermistor to respond to temperature changes.
- Check the actual module pinout before applying power.
