BeanDevice Wilow AX-3D Wi-Fi accelerometer and data logger

The BeanDevice Wilow AX-3D is an ultralow-power Wi-Fi accelerometer with a built-in data logger. It is designed for wireless structural health monitoring, condition monitoring, dynamic measurement on rolling stock and vibration analysis.

The BeanDevice integrates an antenna-diversity design, boosting the radio link quality in environments subject to random and diverse disturbances. Antenna diversity improves both the quality and reliability of a wireless link by 30%.

Due to an onboard shock sensor coming with SSD (smart shock detection) technology, the user can trigger both data acquisition and device wake-up on a shock threshold. A smart energy management system (USB and energy harvesting) allows the product to be powered by the internal lithium-polymer rechargeable battery, a USB power bank or directly from a solar panel. Store and Forward+, a lossless data transmission mechanism, enables a large-scale deployment of Wilow wireless sensors in industrial applications where data transmission is critical.

Ready for IoT applications, the unit integrates MQTT, a lightweight and open-source IoT protocol. Users can quickly set up a scalable IoT application.

With the ability to stores up to 5 million data points, the device is IP67 protected and has a lightweight aluminium casing. It is capable of low noise operation (45 µg/√Hz for the ±2g version), has an antenna range of 200 m and consumes only 60 µA in sleep mode.
