Keyestudio Analog Temperature Sensor Detection Module for Arduino

This module is designed to operate at a standard 5V DC supply, which is compatible with most Arduino boards (Uno, Mega, etc.) and other 5V microcontroller systems. Ensure your power source provides a stable 5V supply for accurate analog readings.

Connect the module's VCC pin to Arduino 5V, GND to GND, and the signal (SIG) pin to any analog input pin (e.g., A0). In your Arduino sketch, use the `analogRead()` function on the chosen pin. You will then need to map the raw ADC value (0-1023) to a temperature value in Celsius using a conversion formula or library specific to the NTC thermistor's characteristics.

The sensor's NTC thermistor supports a wide operating temperature range from -55 degrees Celsius to 315 degrees Celsius. This makes it suitable for a variety of applications, from cold environment monitoring to high-temperature detection projects. Note that extreme temperatures near the limits may affect long-term sensor stability.

For most hobbyist applications, the sensor provides sufficiently accurate readings using standard NTC conversion formulas or libraries. For higher precision, a two-point calibration against a known temperature reference (like an ice bath and boiling water) can be performed to fine-tune the conversion constants in your code and account for minor component tolerances.
