Thermal Temperature Sensor Module Thermistor Switch Sensitivity Adjustable
The Thermal Temperature Sensor Module with Adjustable Sensitivity is a compact and versatile temperature detection module designed for environmental monitoring and automation projects. Operating from 3.3V to 5V DC, it uses a thermistor and an LM393 comparator to provide both analog and digital outputs. The onboard potentiometer allows users to adjust the temperature threshold sensitivity according to application requirements. Equipped with status LEDs and convenient mounting holes, this module is easy to integrate with popular microcontrollers such as Arduino, ESP8266, ESP32, and Raspberry Pi. It is ideal for temperature alarms, smart home systems, and thermal control applications.
وحدة مستشعر الحرارة الحراري مع حساسية قابلة للتعديل هي وحدة مدمجة ومتعددة الاستخدامات مصممة لمراقبة درجة الحرارة وتطبيقات الأتمتة المختلفة. تعمل بجهد 3.3 إلى 5 فولت تيار مستمر وتعتمد على مقاومة حرارية (Thermistor) مع شريحة المقارنة LM393 لتوفير خرج تناظري ورقمي. يتيح مقياس الضبط المدمج تعديل مستوى الحساسية أو درجة الحرارة المطلوبة بسهولة حسب التطبيق. تتميز الوحدة بمؤشرات LED وحفر تثبيت لسهولة التركيب والتكامل مع لوحات التحكم مثل Arduino وESP8266 وESP32 وRaspberry Pi، مما يجعلها مناسبة لأنظمة الإنذار الحراري والمنازل الذكية.
The Thermal Temperature Sensor Module is an easy-to-use temperature sensing solution designed for detecting changes in ambient temperature. The module combines a thermistor with an LM393 voltage comparator, enabling both continuous temperature monitoring and threshold-based switching.
The onboard thermistor changes resistance according to temperature variations, while the LM393 comparator processes the signal and generates a digital output when the preset threshold is reached. Users can easily adjust the trigger point using the integrated blue potentiometer.
The module provides two output modes: an analog output (AO) for real-time temperature measurement and a digital output (DO) for simple on/off temperature detection. Status LEDs indicate power availability and digital output state for quick visual feedback.
Operating at 3.3V to 5V DC, the sensor is compatible with a wide range of development platforms and microcontrollers. Its compact size and mounting holes make installation straightforward in both prototype and permanent applications.
