Products / CA-NBS300 Tilt & Vibration Sensor
The CA-NBS300 tilt and vibration sensor is a low-power, remote wireless tilt and vibration sensor independently developed by Beijing Chengan, developed specifically for outdoor conditions with no power supply.

The sensor remains in standby for long periods, with standby power consumption as low as 0.4 mA.
An angle threshold and an acceleration threshold can be set. When the sensor detects that an object suddenly exceeds the angle or acceleration threshold, it actively wakes the device and uploads the information immediately.
The product is mainly used for tilt and vibration monitoring of buildings, steel structures, bridges and ancient buildings.
The product is precisely designed, with temperature and linearity further compensated, and integrates comprehensive protection functions against short circuits, instantaneous high voltage, reverse polarity and surge, making it suitable for operation in various harsh industrial environments. For reliability and stability, industrial-grade MCUs, three-proof PCB boards, imported cables, wide-temperature metal housings and other measures are also adopted to raise the product's industrial grade.
