The use of a single-chip CMOS IC results in low power drain meaning that module
can operate with low voltage souces such as batteries.
The fresnel lens provides a detection range of 0 -
3m(MS-310) or 0 - 5m(MS-311) with a 70 degree spread.
The module's built-in timer is freely adjustable. It is also possible to adjust
the mask time (after output is terminated) and circuit stabilization time (after power-on)
during which the module will not respond.
Choice of two operating modes: One-shot or Retriggerable.
Ouput current (open collector output) can be adjusted up to a maximum of 0.5
By adding an external Cds, operation can be confined to a
dark environment. Ideal for courtesy and security lights.
MS-330/331 employs a quad-element PIR sensor, optimal for small motion detector.
Automatic lighting switches.
AC/DC sensor lights.
Automated product demonstration.
