A range of highly compact PIR sensors
housed in a TO5 package fitted with a zoned fresnel lens. The sensor detects infra-red radiation in the low infrared spectrum (10µm wavelength) which is emitted by human movement. The sensors are able to detect a change in temperature from object to ambient from as little as 3°C. Changes in the level of detected emission are evaluated by a window comparator, and if the change exceeds the upper or lower threshold the output level of the sensor goes high and can be used to trigger external circuitry.
- Applications include burglar alarms, access control, automatic lighting, automatic door opening, and many other applications where detection of personnel is required
- Four types are available: a 10m long range type, a standard 5m detection range, a 5m spot type and a high sensitivity 2.5m detection range
- All versions are available with either a dark coloured lens (for dark environments) or a light coloured lens for bright environments
- Matsushita AMN series
