WiFi | Wireless IoT Vibration Sensor
BeanDevice® WIFI | Wilow® AX-3D
The BeanDevice® WiLow® AX-3D is an ultra-low-power (ULP) tri-axis Wi-Fi vibration sensor designed for high-precision monitoring of acceleration, peak particle velocity (PPV), and amplitude in industrial and structural applications. Featuring an integrated data logger for reliable real-time performance, this robust sensor offers versatile mounting options (screw or magnetic) and flexible antenna configurations (embedded low-profile Radom or high-gain) to suit various deployment needs. With solar energy harvesting capability, it enables autonomous, maintenance-free operation in even the most demanding environments, making it the ideal solution for continuous vibration monitoring applications. | ||

How it Works ?
Wilow® sensors can easily work with a third-party WIFI access point. Just simply connect your PC/Laptop and your Beandevice Wilow® to your WIFI Access point, and start to receive real-time data stream on your own IOT software ( thanks to MQTT) or our supervision software (BeanScape® Wilow®).
By default , our Wilow® sensors are provided with a free version of our supervision software ( BeanScape® Wilow® Lite) , users can get an access to the IOT sensor Dashboard, visualize real-time graph display , configure MQTT framework and backup data measurement on a log file.
