2026-03-30      Author:Mradmin

As we enter the era of all-scenario intelligence, automated control applications based on human presence sensing are rapidly gaining traction across office, residential, and commercial environments. To address the diverse and specialized requirements of professional installation projects, Merrytek has upgraded and refined the engineering installation sensor product line, delivering precisely tailored smart sensing and control solutions for a wide array of scenarios.

 

Merrytek first launched the SM (Super Mini) Series and the SP (Super Planar) Series. With ultra-compact size, quick installation, and precise detection, these new products empower a diverse scenarios across smart buildings, smart homes, and smart offices etc.

 

 

SM (Super Mini) Series: Ultra-Compact Size, Seamless Integration Across All Scenarios

 

  • Φ35mm compact cutout size allows for seamless flush installation, preserving the original aesthetic integrity of the space.
  • 24GHz mmw presence sensor and PIR motion sensor for option
  • Radar Version: Equipped with Merrytek’s proprietary circularly polarized antenna and upgraded 4.5th generation super sensing technology, effectively mitigating strong reflective interference encountered in small spaces such as bathrooms with tiles or aluminum ceilings.
  • Infrared Version: Features Merrytek’s proprietary MFL01 ultra-flat lens, offering a maximum motion detection radius of 6-7 meters (tangential). Powered by Merrytek’s exclusive AI algorithms, without false triggering even in high temperature environments.
  • Supports parameter configuration via MH10 or MH18 remote control, allowing for flexible adjustment without disassembly.
  • Pluggable terminal wiring design: simple wiring requiring no tools.
