In smart office projects, the smart retrofit of open-plan office areas has always been a key implementation focus. Open-plan office areas feature spacious layouts and a wide distribution of personnel. Conventional PIR sensors have limited detection ranges, requiring higher deployment quantities and costs for large spaces, while being prone to false triggers in high-temperature environments that disrupt the office experience.
To overcome these application challenges, Merrytek proudly launches the SW(Super-Wide) Series new release—the MSA069 IR Series Sensor. Featuring a 15m detection radius, a built-in temperature sensor, and a DIY lens shutter mask, it drastically reduces the number of sensors needed in open offices. This lowers both material and installation costs, providing a highly cost-effective sensing solution for smart office projects.


Utilizing a self-developed custom-molded lens, the MSA069 IR achieves precise detection across an ultra-wide 15m radius, with a single unit controlling an expansive area of up to 700 m².

Equipped with a built-in temperature sensor and an AI High-Temperature Compensation Algorithm, it dynamically adjusts triggering thresholds based on real-time ambient temperature. This effectively solves the pain point of false triggering in high-temperature environments common in traditional PIR sensors, and enabling detection across the full temperature range from -25°C to 50°C.

Included lens shutter masks allow users to customize detection ranges according to actual space requirements, thereby fully meeting the needs of smart retrofit and new construction projects in open-plan offices, coworking spaces, and large public office areas.




From small offices to large open-plan workspaces, different spaces in smart office environments have varying sensor requirements. Based on real-world engineering scenarios, Merrytek has refined its products and launch the MSA069 IR Super-Wide Series, further expanding its PIR infrared sensor product portfolio for large spaces and providing more reliable, cost-effective sensing solutions for smart offices and commercial buildings. Going forward, Merrytek will continue to deliver diverse sensor solutions to support the efficient implementation of more smart space projects.
