3PIN NTC Thermistor Temperature Sensor Module

NTC Thermistor Sensing Component: Utilizes a high-sensitivity Negative Temperature Coefficient (NTC) thermistor element that predictably decreases electrical resistance as ambient temperature rises.

Onboard Signal Comparator: Equipped with an onboard LM393 voltage comparator IC providing clean, stable digital switching output alongside sensitive analog temperature telemetry.

Adjustable Temperature Sensitivity: Features a multi-turn precision potentiometer for setting custom thermal trigger thresholds for automated switching and alarm routines.

Dual Output Modes: Provides both an Analog Output (AO) signal for precise continuous temperature readings and a Digital Output (DO) signal for direct threshold-based triggering.

Built-in Power & Signal LEDs: Outfitted with an onboard power LED and a digital switching status LED for instant visual indication during system operation and calibration.

Board Material: Flame-retardant FR-4 glass-epoxy breakout PCB with gold-plated connection pads and durable blue silkscreen finish.

Technical Specifications:

Operating Voltage: 3.3V – 5.0V DC.

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

Comparator IC: LM393 Differential Comparator.

Temperature Measurement Range: -55°C – +125°C.

Board Color: Blue PCB with Silver Component Traces.

Usage Advice: Wire VCC to 3.3V - 5V, GND to Ground, and DO/AO pins to your microcontroller's GPIO or ADC pins; turn the potentiometer clockwise to adjust sensitivity.

Maintenance: Keep the board surfaces dry, free of dust, and clear of conductive material or solder debris.

Essential Beginner Thermal Sensor: Position as a straightforward, versatile thermal sensing breakout module for Arduino beginners, DIY thermostat builds, and climate control prototypes.

Highlight Dual-Output Flexibility: Emphasize how having both analog and threshold digital outputs allows simultaneous direct microcontroller sensing and automated alarm triggering.

Recommended Cross-Sell Add-ons: Pair with 4PIN NTC Thermistor Temperature Sensor Module, 5V Temperature Sensitive Relay Module, Analog Temperature Sensor Module, and 10K Precision Metal Head Thermistor - 3950 NTC.
