Beanair Wilow AX-3D Wi-Fi accelerometer

Click2Contact

The Beanair Wilow AX-3D is an ultra-low-power Wi-Fi accelerometer with built-in data logger, equipped with a MQTT communication protocol. The sensor is encased in a lightweight, waterproof, aluminium casing with IP67 protection. The tiny Radome Omni antenna enables wireless transmission with a maximum range of 200 m.

The Wilow device is suitable for use in a range of structural health monitoring, condition monitoring and other industrial monitoring applications due to its robustness and reliability to operate in harsh environments. The combination of a high-performing accelerometer and a 24-bit delta-sigma analog-to-digital converter also generates very few undesirable noises.

The Wilow AX-3D vibration sensor is also equipped with a smart shock-detection feature that triggers both data logging and device wake-up once the vibration level reaches a shock threshold.

The Wilow AX-3D also offers the Store and Forward+ lossless data transmission system. When network disruption occurs, data are stored in a Wi-Fi access point or Wi-Fi receiver and then retransmitted to the system on the next transmission cycle when the network is restored.

Wilow devices are designed with a smart energy-management system to allow power supply from an internal lithium-polymer rechargeable battery or external USB, and a solar panel.

By using Wilow sensors for monitoring, users can benefit from lower installation costs and reduced on-site cable complexity.

Key features include: measurement range: ±2 g and ±10 g and data storage: up to 5 million data points.
