“One of the biggest challenges with IoT is that edge devices require a batteries for the sensing and communications, and manufacturing batteries or charging batteries will increase CO2 emissions, while replacing battery requires a lot of manual works. By developing Zero Carbon IoT, we could eliminate battery replacement and easily realize asset tracking in a zero carbon society. We aim to realize a more prosperous society by providing various solutions to our customers.”
Asset tracking using cellular location information presents challenges such as ensuring device power supply, battery life and replacement, as well as communication costs.In addition, it was necessary to prepare a mechanism for managing network servers and identifying location information for customers who use devices.
RYODEN and SMK solved the power supply problem by developing an edge device that uses energy harvesting, enabled tracking by using SEMTECH LR1110 as the LoRa transceiver IC, and solved the communication cost problem by using LoRaWAN.Also, by using BLE, BLE for short-range communication and LoRaWAN for long-range communication are possible with one module.
By adopting Atmosic ATM3202 for the control microcomputer of the LoRa transceiver IC, BLE compensates for the disadvantages of LoRaWAN such as "data transmission", "continuous communication at short intervals" and "large capacity communication".In addition, the ATM3202's low power operation and energy harvesting help extend battery life.
