BeanAir wireless sensor network for in-tunnel air quality monitoring

Click2Contact

Bestech Australia introduces the wireless sensor network from BeanAir, suitable for monitoring emissions and air quality in tunnels. The system consists of an AN420 wireless sensor, a BeanGateway wireless coordinator and BeanScape software for supervision, control and remote monitoring.

The AN420 is an analog wireless data acquisition system with an integrated data logger. It is compatible with any sensors providing 4–20 mA (current-loop) input and is able to measure air flow, CO, NO_x and CO₂ concentration. The sensor is directly powered by an adjustable DC/DC converter inside the device.

When multiple sensors are installed inside the tunnel, the BeanGateway wireless coordinator can easily manage queues for every BeanDevice, convert data, manage IP connectivity and control external access to the network through a highly secure authentication protocol. It is compatible with Ethernet and Modbus connectivity (RS232 and RS 485). It can also be used in conjunction with other BeanGateway devices and offers easy data export/import function for flexibility.

The BeanScape software offers a user-friendly interface and can be easily integrated to a third-party supervision software. It can also simultaneous handle several BeanGateway and automatically back up the flash memory of each device for easy maintenance. The software also offers comprehensive data analysis tools and automated exporting to standard report format (Excel, PDF and Word).

Other features include: autonomous monitoring with ultralow battery consumption (up to seven years); compatibility with several transmission protocols; and an integrated data logger, storing up to 1 million data points.
