A World First: Battery-free Wireless Sensor Integrates All Functions Into Single Module
EnOcean Sensor Transmitter Module 110 ideal for vehicle monitoring
Finally. A complete package.
The world's first wireless, battery-free...and affordable...sensor transmitter to integrate all sensor functions into a single module has been unveiled in North America for OEMs developing products for advanced metering infrastructures.
The EnOcean STM (Sensor Transmitter Module) 110 harvests and stores solar energy, converts DC to DC efficiently, measures incoming data with ultra low power electronics and transmits via radio signals.
"Battery-free, wireless sensor modules need to be designed as an integrated package," said Jim O'Callaghan, EnOcean's vice president of Sales & Marketing, North America. "Piecing together components from different suppliers is inefficient because they have not been optimized to work with each other."
The integrated STM 110 module makes possible scalable and continuously adaptable sensor networks that can sense and transmit data on temperature, gas, humidity, vapor, current, light levels, water, pressure, location, occupancy and other parameters. Its dimensions-0.8 in. by 1.6 in. by 0.4 in. (21 mm x 40 mm x 9 mm)-allow it to be incorporated into very small OEM products and facilitate enhanced product aesthetics. The module advances proven technology with over 300,000 units operating in more than 10,000 buildings in Europe and North America, including ones installed in SAP and Nestle facilities.
Since the module requires neither line voltage nor batteries, it is virtually maintenance free. It eliminates such battery headaches as unpredictable service life, replacement and disposal, yet is cost competitive with battery-based systems.
STM 110-enabled products can be designed for quick and easy peel `n stick installation practically anywhere. Products can be moved readily as floor plans or monitoring requirements change. Most installations do not require outside electricians or added networking overhead for managing the radio frequency.
The module is fully compatible with existing sensors and industry-standard networks, such as LON, Ethernet, group receivers and central building controllers. It can communicate with multiple receivers, allowing exceptional flexibility in designing sensor networks.
A thin layer solar cell requires only five foot-candles to generate electricity. It produces more than enough power to drive both the sensor and the module's radio, which has more than a 100 ft. indoor range through walls. An energy accumulator stores power for days, enabling the module to operate in total darkness. The module represents a breakthrough in the creation, storage and management of power.
Performance characteristics include an industry best ultra-low power sleep timer, fast wake up cycles where sensor measurement and RF transmission occur in less than four milliseconds, configurable signal trigger thresholds and standardized data profiles and producer identification to enable cross- vendor interoperability.
