4PIN NTC Thermistor Temperature Sensor Module

NTC Thermistor Sensor Element: Employs a high-sensitivity Negative Temperature Coefficient (NTC) thermistor component that exhibits predictable resistance drops as ambient temperatures increase.

Dual Simultaneous Signal Outputs: Features both a continuous Analog Output (AO) for precise microcontroller temperature telemetry and a Digital Output (DO) for direct threshold trigger switching.

LM393 Comparator Circuitry: Onboard LM393 differential voltage comparator provides clean, noise-free digital square-wave signals to host controller boards.

4-Pin Header Layout: Dedicated VCC, GND, DO (Digital Output), and AO (Analog Output) pins provide simplified interface options with DuPont jumper cables.

Onboard Sensitivity Trimmer: Includes a multi-turn potentiometer to allow fine adjustment of the digital temperature trigger point for custom thermal threshold routines.

Board Material: High-grade FR-4 glass-epoxy breakout PCB with gold-plated pin header contacts and blue protective solder mask.

Technical Specifications:

Operating Supply Voltage: 3.3V – 5.0V DC.

Signal Outputs: Dual Analog (AO) + Digital Switching (DO).

Comparator IC: LM393 Differential Comparator.

Sensing Temperature Range: -55^C – +125^C.

Board Color: Blue PCB with Silver Circuitry Traces.

Usage Advice: Connect VCC (3.3V - 5V) and GND, then connect AO to an analog ADC pin for temperature logging or DO to a GPIO pin for digital switching; turn the potentiometer to calibrate the digital threshold.

Maintenance: Keep board surfaces clean and dry, avoiding exposure to conductive metal filings, high humidity condensation, or corrosive solvents.

Essential 4-Pin Thermal Sensing Module: Position as an indispensable starter module for Arduino and ESP32 project kits, DIY thermostats, fan controllers, and over-temperature alarm prototypes.

Highlight Dual Digital & Analog Outputs: Emphasize how the 4-pin design provides maximum interface flexibility by outputting both raw analog voltage readings and instant digital threshold switching on a single board.
