What is the Wireless Sensor Network?
The Wireless Sensor Network consists of nodes (child machines) incorporating various sensors, bases (parent machines) that receive measurement data from the nodes, routers (relays) that relay the data, and a generator that controls air conditioning and light devices. The data is transmitted by low power radio, eliminating the need for wiring.
Basic Technologies
We incorporate a solar cell and a Li secondary battery to power the temperature/humidity meter and illuminometer, applying our ultra-low power consumption technologies which we have utilized as a watch manufacturer to achieve an industry-first: a wireless sensor network that runs off solar power. During shipping, a fully charged solar cell can continue to operate for roughly 30 days without a light source. The JIS (Japanese Industrial Standards) recommends office lighting at a luminous intensity of 750lx; our device will run off regular room light of 300-400lx for extended periods.
Three Features of the Wireless Sensor
- Space savings
One system can have up to 100 nodes (child machines) or routers (relays). Devices are compact for easy installation in confined spaces. - Maintenance-free
The device uses a solar panel, eliminating the need for battery replacement. - Wireless
The low power radio eliminates the need for special certification. The wireless design also significantly reduces costs related to wiring for system installation. Field tests have confirmed communication at distances of 30m from the distribution switchboard.
