Until now, WIFI technology was extremely energy greedy and unreliable. Users working on structural health monitoring, test and measurement and condition monitoring were more inclined to deploy proprietary wireless sensor networks offering a better reliability and a low power operation.
Thanks to more than 8 years of experience in sensing technology, Beanair’s research and development team worked intensively with our customers on WiLow® technology (for Wifi Low Power), a new generation of WIFI sensors (vibration, inclination and shock) which is reliable, ultra-low power and open-standard.
WiLow® sensors revolutionize sensing technology by bringing outstanding features:
- ULP (Ultra Low Power) Wifi Technology – IEEE 802.11 b/g/n (2.4 Ghz frequency band)
- Embedded Data Logger with more than 5 million data points (with events dating)
- Smart and flexible power supply, compatible with USB and Solar power sources.
- SSD (Smart Shock Detection), WiLow® sensor can wakeup on shock detection (software configurable)
- Rugged aluminum casing waterproof IP67 | NEMA 6
- USB 2.0 for device configuration (including firmware update)
- Lossless data transmission with hard real-time
By connecting WiLow® sensors to existing WIFI infrastructure, user can benefit from a rapid return on investment:
- Lower total cost of ownership-works
- Large installed base and consequent broad-based familiarity with configuration, use and troubleshooting at the physical and link layers
- Easy provisioning & IT friendly: WiLow® sensors use IP-over-Ethernet networking environment
GET READY FOR INDUSTRIAL INTERNET OF THINGS (IIOT)
Ready for Industrial Internet of things (IIOT) applications, WiLow® sensors integrate natively MQTT (Message Queuing Telemetry Transport) data frame, a lightweight and open-source (OASIS & ISO/IEC 20922:2016 standards) Internet of Things protocol.
MQTT is designed to support wireless networks with varying levels of latency due occasional bandwidth constraints or unreliable connections. It is extremely easy to use and lightweight. The protocol uses a publish/subscribe architecture in contrast to HTTP with its request/response paradigm.
It is based on publish/subscribe paradigm, therefore user can easily connect, configure and manage several WiLow® sensors at the same time from a unique IOT software platform.
No need to spend several months to develop a specific and complex supervision software, user can easily integrate WiLow® sensors in a third-party IOT Cloud platform (Amazon web services, IBM Watson, Microsoft Azure, Facebook Messenger, Alibaba Cloud….).
Non-developer users can still use the BeanScape® software to setup a quick and affordable Wifi sensor network.
TRIGGER YOUR DATA ACQUISITIONS ON A SHOCK DETECTION
Thanks to our Smart Shock Detection (SSD) technology, WILOW® sensors can wakeup on a shock detection and starts immediately data acquisition and real-time wireless transmission.
Unsolicited wakeup can be avoided by configuring a shock threshold (up to 16g) and a hysteresis.
User will spend less time to analyze useless data acquisition as data recording & wireless transmission will start when a shock threshold is reached. Battery life can be extended as WILOW® sensors are most of the time in sleep power mode.
A RELIABLE WIFI TECHNOLOGY THANKS TO OUR “STORE AND FORWARD+” FUNCTION
The store and forward technique works by storing the message transmitted by WILOW® sensors to a Wifi access point/ Wifi receiver. If the message is not received due to a network disruption, it will be retransmitted on the next transmission cycle. This technique allows to bring a lossless data transmission.
User can also enable the hard-real-time option; i.e. the message must be received by the Wifi Access Point/Wifi Receiver within the confines of a stringent deadline. It is automatically deleted if it failed to reach its destination within the allotted time span.
SMART AND FLEXIBLE POWER SUPPLY
WILOW® sensors can be power supplied from different power sources:
- Internal rechargeable Lithium-Polymer battery
- USB 5VDC power supply, therefore compatible with any kind of USB power bank available on the market
- External power supply 5VDC up to 17 VDC including solar panel, no need to use an external solar power manager
