NTC Thermistor Temperature Sensor Module

The NTC Thermistor Temperature Sensor Module is a highly sensitive, low-cost solution for environmental temperature monitoring. Unlike standard analog sensors, this module features an onboard LM393 voltage comparator chip, allowing it to provide a clean, stable digital signal. It is specifically designed to detect when the surrounding temperature passes a specific user-defined limit.

High Sensitivity and Dual LEDs

This module is exceptionally sensitive to ambient temperature changes. It includes two onboard LED indicators: one for power (Power LED) and one for the digital switch output status (D0-LED). This visual feedback makes it incredibly easy to calibrate your temperature trigger point without needing to look at a serial monitor.

Key Features

• Digital Output (DO): Provides a simple High/Low signal for easy microcontroller detection.

• Adjustable Threshold: Onboard potentiometer allows you to set the exact temperature trigger point.

• LM393 Comparator: Ensures a clean, stable signal with strong driving capability (>15mA).

• Dual Status LEDs: Instant visual confirmation of power and trigger status.

• Small Form Factor: Compact design with a fixed bolt hole for easy installation in enclosures.

Technical Specifications

Typical Application Scenarios
