April 24, 2020 -- Fujitsu Component America has released a series of battery-powered Wirepas Mesh technology mesh units and mesh-sensor units. The devices are designed to aid construction of large-scale decentralized networks to allow IoT solutions for position tracking and sensor data collection. In addition to deploying large-scale networks, the mesh units (FWM8BLZ07P) and mesh-sensor units (FWM8BLZ07Y) enable networks with interference tolerance channel selection, transmitting power control and autonomous network rerouting capability. If the network environment changes, adds and/or removes the end device, or if a device failure occurs, the mesh topology and protocols will automatically reconfigure the mesh network.
Furthermore, a security key ensures a secure communication environment throughout the network. The FWM8BLZ07P mesh unit is suited for wide-area asset tracking. It features a long-sleep mode and an integrated sensor that wakes up only if certain events, like shock, are detected. This function further conserves energy because communication begins only when needed. The multi-function FWM8BLZ07Y mesh-sensor unit incorporates a combination of temperature, humidity, air pressure, illuminance, 3-axis acceleration, and sound-level sensors.
This makes it adaptable for a variety of massive, sensor data collection systems with scalable mesh topology. Since the sensor data paths through the mesh network topology, the end-node’s placement is not limited by the gateway's location.
Both mesh units are based on the Nordic Semiconductor nRF52832 SoC and measure a 40.0 x 31.0 x 12.0 mm within a gray, plain housing, adaptable for many applications. They use a CR2450 coin-cell battery and include a voltage notification function, which senses a voltage drop in the battery and allows users to determine the right timing for replacement.
