Digital Temperature Thermistor Module

NTC Thermistor Sensing Probe: Uses an integrated Negative Temperature Coefficient (NTC) thermistor element for fast, sensitive response to ambient temperature changes.

Onboard Signal Comparator: Outfitted with an LM393 differential voltage comparator IC to deliver high-stability digital switching logic free from signal noise.

Adjustable Temperature Threshold: Includes a multi-turn precision potentiometer for fine-tuning custom thermal trigger setpoints for control and alarm systems.

Dual Signal Output Pins: Features an Analog Output (AO) pin for continuous temperature telemetry and a Digital Output (DO) pin for direct logic switching.

Visual LED Indicators: Equipped with a red power status LED and a green digital output status LED for quick visual verification during operation and setup.

Board Material: Flame-retardant FR-4 glass-epoxy breakout PCB with gold-plated pin header contacts and red 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.

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

Board Color: Red PCB with Black and Blue Components.

Usage Advice: Connect VCC (3.3V- 5V) and GND, connect DO to a GPIO pin for digital switching or AO to an ADC pin for analog monitoring, and rotate the potentiometer to adjust trigger sensitivity.

Maintenance: Keep board surfaces clean, dry, and clear of conductive metal particles or solder flux residue.

Essential Beginner Climate Control Module: Position as an accessible, multi-purpose thermal sensor breakout for Arduino, ESP32, and Raspberry Pi prototyping, DIY thermostats, and automated fan control.

Highlight Dual Output Versatility: Emphasize how having both raw analog voltage readings and instant digital threshold output on a single board eliminates complex external circuit designs.

Recommended Cross-Sell Add-ons: Pair with 3PIN NTC Thermistor Temperature Sensor Module, 4PIN NTC Thermistor Temperature Sensor Module, 5V Temperature Sensitive Relay Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
