How is that power supplied ? Internal Battery : 750 mAh Lithium-Polymer battery Extended operating temperature: -40°C up to 60°C USB 5VDC power source User can connect it to any kind of USB Powerbank Option for Energy Harvesting power source Easy connection to any kind of energy harvesting power source Compatible with small solar panel from 5VDC to 17VDC, no need an external solar power manager 13

How to enable a remote access on Monitoring site (1/2) ? The Wilow® IOT Gateway supports both WIFI and 3G/4G/LTE wireless protocols and allows a very easy connection to our Wilow® IOT sensors. Thanks to WDS (Wireless Distribution System) function, a wireless bridging with other WIFI Bridges/Repeaters can be configured for a better wireless network coverage. . • Consult our dedicated webpage for dedicated to : click here

Ready for Internet of Things (1/2) ? Ready for Industrial IOT (Internet of things) applications, the Beandevice® Wilow® integrates MQTT (Message Queuing Telemetry Transport) data frame, a lightweight and open-source (OASIS & ISO/IEC 20922:2016 standards) Internet of Things protocol. MQTT is based on publish/subscribe paradigm, therefore user can easily connect, configure and manage several Wilow devices at the same time from a unique IOT software. For more information about our MQTT Toolkit: Click here Source codes are available for free in C#, Android, NodeRed, Python and Labview:

Ready for Internet of Things (2/2) ? How is that working ? The Beandevice® Wilow® is hosting both a Publisher (Data Acquisition, Network Diagnostic) and a Subscriber (Over the air firmware upgrade, Over the air configuration). MQTT Broker will play an important role in data exchange: Should the connection from a subscribing client (Laptop or Mobile device) to the broker get broken, the broker will buffer messages and push them out to the subscriber when it is back online. Should the connection from the publishing client (BeanDevice® Wilow®) to the broker be disconnected without notice, the...
