Energy Harvesting

This paper discusses the design and use of a cellular IoT application circuit that is powered from harvested energy. The application combines GNSS-based positioning as well as short range (Bluetooth) and cellular (NB-IoT and LTE-M) communication. The solution developed uses the u-blox SARA-R4 (LTE Cat M1 / NB1) or the u-blox SARA-N2 (LTE Cat NB1) cellular modules, the u-blox NINA-B1 Bluetooth low energy module and applications processor, and the u-blox ZOE-M8 GNSS receiver. In addition there are several sensors for ambient light, UV, motion, temperature, humidity, magnetic detection and air pressure. A video of the vibration harvester example is available on YouTube. While energy harvesting is the focus of this paper, all the techniques described apply just as well to any ultra-low power system operating from a primary battery.

Accurate timing for the IoT

Time synchronization is crucial in all network applications, from the Internet to industrial, financial, and scientific applications. This has led to the development of a variety of approaches to achieve highly accurate synchronization of devices across networks. Today, the spread of the Internet of Things (IoT) is changing the timing game. An increasing number of distributed applications are wireless, so we face a big opportunity but also a challenge, how do we distribute highly synchronized timing wirelessly?
