The KY-013 Analog Temperature Sensor Module uses a thermistor to measure ambient temperature based on the resistance of the device.
- The temperature sensor is a NTC thermistor
- Multi-point temperature measurement Measures temperatures: -55°C / +125°C
- Accuracy: + / – 0.5°C
Connection
Connect board’s power line (middle) and ground (-) to 5V and GND respectively. Connect signal (S) to pin A0 of the Arduino.
