Sensors integration

Integration of diverse sensors into IoT ecosystem is a challenging task and needs skills in hardware design and software development. Sensors have to be orchestrated together in order to form a complete system. Sensor node in IoT is not only a sensor, other accompanying components include A/D converter, microprocessor, power model. BioSense IoT group leverage microprocessors to deploy sensors, including ones developed at Institute, and thus design flexible IoT solutions. Furthemore, BioSense IoT group study different transmission modes, estimate energy consumption and optimize parameters and scheduling to maximize sensor node lifetime.

When it comes to wireless integration of sensors and meteo stations, today’s state-of-the-art standard for IoT networks is LoRa. It is optimised for sending small batches of data (sensory readings) over vast distances with small energy consumption. This allows sensors to be installed in fields without access to power lines and Wi-FI. Due to its high efficiency the battery can last throughout the whole growing season and data logging is possible from fields up to 20 km away from the base station. BioSense focuses on deployment of custom-made LoRa networks and integration of sensors inside them. An example of this is the network of 500 weather stations that will be deployed throughout the Republic of Serbia. They will allow for measurements of meteorological parameters on a high spatial resolution and help farmers make optimal decisions based on the local conditions at the farms.
