The Dinsafer Helio DPMH1 is a wireless passive infrared motion sensor designed as an accessory for the Helio smart alarm system. It detects human body movement within a 110° field of view at up to 9 m, while its pet-immunity function prevents false alarms from animals weighing up to 20 kg.

Automatic temperature compensation keeps detection accurate across varying ambient temperatures. The sensor runs on two AA batteries and includes energy-saving and low battery warning functions, making it straightforward to install and maintain.

Key Features

• 110° detection angle with 9 m detection distance
• Pet immunity for animals up to 20 kg
• Automatic temperature compensation technology
• Wireless transmission at 433.92 MHz, up to 1000 m without obstacle
• Low battery warning function
• Powered by 2 × AA (1.5 V) batteries

Product Benefits

• Pet immunity eliminates false alarms from household animals, reducing unnecessary alert interruptions
• Temperature compensation maintains consistent detection sensitivity regardless of ambient temperature changes
• A 1000 m open-air transmission range gives installation flexibility across large or multi-room properties
• The low battery warning notifies users before the sensor loses power, preventing unmonitored gaps in coverage
• At 85 g without batteries, the compact 100×60×48 mm body installs unobtrusively in corners or on walls
