    Fujitsu Develops World’s Smallest Sensor Device that Supports LPWA Communication

    New technology eliminates need for battery replacement.

    Fujitsu Laboratories Ltd. announced the development of the world’s smallest sensor that eliminates the need to replace batteries. The new sensor supports Low Power Wide Area (LPWA) wireless transmission technology that can reach a broad area with low power.
     
    As the spread of IoT systems gains momentum, expectations are rising for sensor devices that support LPWA technology, which can wirelessly transmit sensor information directly to the cloud. In order to create systems that employ this technology, there has been a demand for the development of easy-to-install miniature devices using solar cells to achieve both convenience and low cost, which dispense with the need to replace batteries.
     
    Fujitsu Laboratories previously developed power control technology that can operate a beacon with the power provided by a solar cell. Now, Fujitsu Laboratories has developed technology that achieves high power efficiency by controlling signal transmission timing based on the temperature variation measured by a temperature sensor, which makes it possible to reduce the required energy storage elements for signal transmission by half.
     
    This has enabled Fujitsu Laboratories to successfully miniaturize the device to a size of 82x24x6 mm, creating the world’s smallest sensor device supporting LPWA that does not need replacement batteries.
     
    Fujitsu Laboratories has previously developed power control technology using miniature circuits that can transmit data over short distances wirelessly using Bluetooth Low Energy (BLE). This technology realizes sensor devices that support BLE without the need to exchange batteries, providing power with solar cells, and reliably activating a wireless circuit by monitoring and adjusting the balance between power generation and consumption.
     
    Sensor devices using this previous technology, however, could not support LPWA. That’s because the time required for transmission with LPWA is significantly longer than with BLE. LPWA transmits small amounts of data slowly in order to ensure signal quality over long distances. In effect, this means that a single transmission can require significant power usage of up to about 1,500 times of BLE.
     
    Fujitsu Laboratories has developed power control technology that can control the timing of LPWA signal transmissions in real time, based on temperature data collected from a temperature sensor.
     
    With this technology, signal transmissions are only carried out at the time when the activation voltage, which varies with temperature, is maximized in order to prevent it from falling below the minimum operational voltage for LPWA module. By using power efficiently in this way, it is possible to tolerate variation in power consumed by the wireless circuit or power generated by solar cells due to temperature.
     
    In order for the power control technology to operate reliably, the device must be able to continually and reliably activate the temperature sensor with a small amount of power. To resolve this challenge, Fujitsu Laboratories has developed power monitoring technology that analyzes voltage changes in power source, and accurately judges whether or not sufficient power has been stored to operate the temperature sensor. This technology can prevent unnecessary shutdowns of the temperature sensor by using the minimum amount of power based on the temperature.
     
    Fujitsu Laboratories verified that temperature and humidity data could be transmitted once every 10 minutes, over seven days directly to a base station about 7 km away, in an environment with illumination of 4,000 lux.
