Vibration Sensor Module

Beanair’s WILOW AX-3D Sensor

Beanair’s WILOW AX-3D sensor is a highly advanced, ultra-low-power (ULP) wireless IoT vibration sensor designed to meet the demands of ground vibration monitoring. This compact yet rugged sensor ULP Wi-Fi technology (IEEE 802.11 b/g/n) allows seamless integration with existing Wi-Fi infrastructure and reduces the overall cost and complexity of deployment. It offers exceptional connectivity with a robust “store and forward” feature that ensures lossless data transmission even during network disruptions by retransmitting lost messages in subsequent cycles.

Vibration Sensor

Performance Metrix

The WILOW AX-3D sensor is equipped with a high-precision accelerometer available in two measurement ranges: ±2g and ±10g. This versatility supports advanced vibration analysis, peak particle velocity (PPV) calculation, and displacement measurement. With a sampling rate of up to 2 kSPS per axis, the sensor delivers precise and reliable data critical for dynamic monitoring. Its MEMS-based accelerometer ensures sensitivity, low noise spectral density, and a robust frequency response of up to 800 Hz.
