The smallest of all Nanoenvi ® systems connects many several sensors in a very small device for Internet of Things (IoT) applications.
The design of the Nanoenvi ® MOTE devices, completely developed by ENVIRA, guarantees the highest levels of safety and reliability and that they can be tailored according to the monitoring needs of each client. They are low-consumption devices that can be powered, if necessary, by small solar panels.
The Nanoenvi motes (remote sensors) are made of ASA Luran, a very light and resistant plastic compound that, together with the thermo-sealing with Elastosyl rubber and silicon, provides them with an IP67 protection level. This ensures their correct performance in the most aggressive surroundings. Due to their resistance, compact design and capacity to perform autonomously (with solar panels), the sensorics can be installed anywhere.
The Nanoenvi MOTE equipment can control and monitor several combinations of inlets, both analogical and digital, from sensors or industrial equipment (through the most usual field buses).
The Nanoenvi motes have different connectivity configurations, which ensures their integration in any IoT communication network by means of the usual M2M protocols: WiFi, 3G, Ethernet, 6lowpan, LoRa, Bluetooth, XBee/ZigBee, etc. The Nanoenvi motes are plug’n play devices and include, in all their versions, the standard programming needed to integrate them in the IoT platform chosen by the client -public product or owner- by means of standard protocols such as CoAP, REST or MQTT. In the case of owner platforms or with a specific configuration, the client must provide the connectivity specifications required.
Notwithstanding the technical limits imposed by their reduced consumption, the Nanoenvi motes have enough capacity to fulfill the most usual Edge operations: signal additions, filters, smoothings, pre-processing information, threshold assessment (to detect alert events), etc. The internal buffering system and the different sampling and communication policies that can be implemented allow the Nanoenvi motes to keep taking measurements even if the connectivity has been cut off.
Watering monitors in green areas and golf courses: As water resources are scarce and there are many regulations for minimizing water consumption, the effective control of watering levels in green areas and golf courses has become very important. Our solution to monitor soil humidity provides managers with valuable information to decide whether watering is necessary or not. The information is wirelessly sent to a local server or to the cloud, so that data can be available for any connected device.
Flood alert system: Flood alert systems near rivers, reservoirs or other water courses provide critical information to protect people and properties. Our system of sensors at the level of the water flow uses cutting-edge ultrasonic technology. 3G mobile phone communications and the power by batteries and solar panels make this solution an autonomous and reliable one to detect possible floods and their importance.
Monitoring building structural health: Buildings, bridges and other structures are likely to be damaged by natural phenomena, building works nearby, floods or simply by the passing of time or the decay of the materials. Our devices allow to monitor several parameters of the structure and to prevent damages that imply expensive repairs and risks for people.
Machine connectivity for industry 4.0: Many machines with old designs lack the possibilities for communication that industry 4.0 technologies provide.
