NTC Thermistor Temperature Sensor Module 4Pin

Key Features

• NTC Thermistor Sensing: It uses an NTC thermistor that has a negative temperature coefficient, meaning its resistance decreases as the temperature rises. This allows for accurate temperature measurements in a wide range of environments. Temperature Range: The temperature range typically varies based on the specific thermistor used but can cover a range from -25°C to +80°C or higher, depending on the thermistor's specifications. The module is generally suitable for both indoor and outdoor temperature monitoring applications. 4-Pin Configuration: The module typically features four pins: VCC: Power supply (usually 3.3V or 5V depending on the module design). GND: Ground connection. Signal Output: Provides the analog voltage signal that varies with the temperature. Reference Pin (optional): Sometimes used for additional calibration or signal conditioning. This configuration allows easy connection to a microcontroller (like Arduino or ESP32) for reading and processing the temperature data. Analog Output: The module typically provides an analog voltage output that changes with the resistance of the thermistor, which varies based on temperature. This output can be read by an analog-to-digital converter (ADC) of a microcontroller to determine the temperature. Some modules include signal conditioning circuitry to make the output more stable and linear. Accuracy and Precision: The accuracy of the module depends on the thermistor's characteristics, but generally, NTC thermistor-based sensors provide good accuracy with typical errors in the range of ±1°C to ±2°C. The response time is usually fast, making it suitable for dynamic temperature monitoring in various applications.
