Bulk pack of 10 modules: a complete set of 10 SW420 vibration motion sensor modules, ideal for larger projects or multiple installations. Extended trigger time: longer trigger duration than standard sensors, providing enhanced reliability and responsiveness in security systems. Efficient signal output: strong comparator output ensures clean signals with a drive capability exceeding 15 mA, making it compatible with various relay systems for seamless operation. Space saving design: dimensions 2 cm x 1.4 cm, a compact module that fits easily into designs without taking up excessive board space. Use scenarios Home and office security systems: use for vibration detection on doors or windows, with the module driving relays or alarm controllers due to its drive capability and clean signal output. Industrial and equipment monitoring: monitor machinery vibrations to trigger alerts or controls; the extended trigger time supports reliable detection of intermittent events in tight spaces. Prototyping and multi site deployments: the bulk pack of 10 reduces per unit cost and enables quick scaling across laboratories, workshops, or installer projects.
