NTC Thermistor Temperature Thermal Sensor

What it is: A temperature-sensing electronic module featuring a Negative Temperature Coefficient (NTC) thermistor, whose electrical resistance decreases as the temperature rises.

Key Specs & Variants:

• Typically available as a bare 2-pin thermistor component or mounted on a 3-pin/4-pin sensor module.

• Analogue & Digital Outputs: Module versions feature an onboard LM393 comparator providing both an Analogue Output ($AO$) for precise temperature readings and a Digital Output ($DO$) for simple threshold trigger alerts.

Key Features: Includes an onboard potentiometer to adjust the digital switching threshold point, plus a power indicator LED.

Common Uses: Temperature monitoring, over-temperature alarms, thermostat controls, and environmental data logging in Arduino, ESP32, and Raspberry Pi projects.
