Nature 4.0 is an innovative start-up. Currently the company has created several devices on microprocessor and wireless data transmission via radio (LoRa) for monitoring environmental parameters with applications in the agricultural and forestry fields. In particular, the company has developed a device called TreeTalker® capable of measuring in real time the water consumption of trees, the growth of biomass and the state of health of the leaves through spectral indices. The elements of innovation concern the extension of the concepts of Industry 4.0 based on IoT and low-cost microprocessor sensors to the environmental and agricultural. The brand new device we will present is TreeTalker®-Cyber, the evidence of our technology improvement.
