In collaboration with Orange, the Fundación i2CAT has developed a stand-alone sensor, which works with solar and artificial light that can be used in applications such as monitoring of street furniture or the prevention of natural disasters.
The I2CAT Foundation It has been one year in the Smart City Expo World Congresswhich closed its doors in Fira Gran Via in Barcelona yesterday, and took their attendance to present a new sensor-operated outdoor, solar, and indoors, using artificial light.
It's an innovative solution that allows a high degree of autonomy of the components that make up the basis of any smart, city as well as a long duration.
The solution is the result of a collaboration with Orange to develop a sensor that operates stand-alone, wireless and without batteries, both outside and inside. To do this, the batteries have been replaced by supercapacitors, a new type of accumulators of energy that can recharge devices about 250,000 times, compared to the thousand of times that can make it a battery charged by solar energy.
This technology allows to make a display indoors and with artificial light, conditions that would allow a useful sensor life much higher than the 25 years on average estimated may have abroad, because the solar radiation does not impair it.
Thus, explains Josep Paradells, director of the Fundación i2CAT, "we have sensors that are loaded in a similar way to as for decades, does any Calculator solar that we have in the office".
For Paradells, the complex has been designing, as "wanted to do something that was small and cost little, using commercial components. IoT is to be a reality, we need innovative, of infinite operation with very low consumption energy accumulation techniques."
Applications that could have this new type of sensor, include the monitoring of urban furniture, that could continue to operate if they are located or in an enclosure without sunlight, or the prevention of natural disasters, through the monitoring of different parameters such as fire, the water level in the rivers or the detection of tremors in infrastructure caused by earthquakes, among other uses.
On the other hand, Daniel Camps, director of Mobile Wireless Internet of i2CAT, gave the fair a talk in which emphasized the commitment of the Foundation by LoRa technology.
It is a low frequency technology to data transmission machine to machine (M2M) that allows a sending of data over long distances and at a very low cost, helping to the proliferation of the Internet of things.
Camps explained how smart cities are becoming a reality but meet some problems, mainly the cost of infrastructure development in the city. A technology that assists in the solution of this problem is the use of wireless technology for low-power local area network, in which LoRa would be one of its applications.
