Meshlium is a router built on the Linux platform that acts as a gateway in the network of wireless sensors. It contains 6 different interfaces: WiFi 2.4GHz, WiFi 5GHz, 3G/GPRS, Bluetooth, XBee and LoRa. Meshlium is easily integrated with mobile and traffic applications: Operates using solar power and a battery, therefore, the device is ideal for outdoor use as well.

Selected features:
Processor: 500 MHz (x86)
Power: 5W (18V)
Material: Aluminum 


Case Study: Monitoring of water quality and air quality in Oviedo, Spain

VisionTech4Life project focuses on research regarding the environmental impact of construction works and its mitigation. The project enables the measurement of water quality, air quality, noise intensity and other atmospheric parameters in real time, and the entire system is based on wireless sensor network and Libelium technology. The project is equipped with Waspmote Plug&Sense! sensors associated with Meshlium gateway with public IP address. One of the nodes is M2M connections and three others use Zigbee 802.15.4 communication protocol.

This system reduced the time for the measurement and monitoring of environmental impacts between 40% and 80%, and reduced latency in alarming situations by 90%. This method has brought 40% reduction in costs incurred in taking measures for correcting negative environmental impacts. The system not only allows minimizing damage, but also stops damage just at the moment when it starts happening.

This project has been deployed in the "Villapérez" water treatment plant, which is located in Oviedo (Asturias, Spain).
