Ultra-Compact High Accuracy Earthquake Detection Sensor Module
ROHM released an ultra-compact high accuracy seismic detection sensor module, BP3901, which is ideal for applications requiring reliable earthquake detection, such as automatic doors, unmanned transport vehicles, and smart meters. The new sensor BP3901 integrates an original earthquake detection algorithm and offers high accuracy. The sensor feature built-in false detection prevention function and can accurately distinguishing between vibration due to earthquakes or other external factors.
BP3901 specifications
- Size: 11.8 x 8.6 x 2.5 mm
