MQ Series Sensor Socket Breakout
The MQ Series Sensor Socket Breakout is a 7-pin universal mounting base designed for MQ-series gas sensors such as MQ2, MQ3, MQ7, MQ9, and MQ135. Made from durable PC plastic and metal contacts, this white socket allows gas sensors to be easily plugged in and removed without direct soldering. It solders onto the gas alarm PCB, providing a reliable and reusable connection. This makes sensor replacement quick, safe, and convenient for DIY and professional gas detection projects.
قاعدة توصيل مستشعرات سلسلة MQ هي مقبس عالمي بـ 7 أطراف مصمم لمستشعرات الغاز من سلسلة MQ مثل MQ2 وMQ3 وMQ7 وMQ9 وMQ135. مصنوعة من البلاستيك PC المتين وأطراف معدنية، ويسمح هذا المقبس الأبيض بتركيب المستشعرات وإزالتها بسهولة دون الحاجة إلى اللحام المباشر. يتم لحامه على لوحة الدوائر الخاصة بجهاز الإنذار ليوفّر اتصالًا موثوقًا وقابلًا لإعادة الاستخدام، مما يسهّل استبدال المستشعرات في مشاريع كشف الغازات.
The MQ Series Sensor Socket Breakout is a specialized mounting accessory designed to simplify the integration of MQ-series semiconductor gas sensors into electronic projects. Instead of soldering the sensor directly onto the printed circuit board—a process that exposes the sensitive sensor element to heat damage and makes replacement difficult—this 7-pin plastic socket acts as an intermediary connector. The socket itself is soldered onto the PCB, and the gas sensor is then simply plugged into the socket, allowing for easy insertion, removal, and replacement without any rework. This is particularly useful because MQ sensors often need to be calibrated, tested, or swapped between different gas-detection applications. The socket is compatible with a wide range of popular MQ sensors including the MQ2 (smoke and flammable gases), MQ3 (alcohol), MQ7 (carbon monoxide), MQ9 (CO and flammable gases), and MQ135 (air quality). Its durable construction ensures a stable mechanical and electrical connection, making it the preferred choice for gas alarms, air quality monitors, and industrial safety devices.
