Power constraint is a critical consideration undertaken by designers when selecting a microcontroller for an application — particularly with IoT applications where power plays a vital role. IoT nodes are only useful in the field if they last for years or even a decade on a single battery. The race for lower power devices between…
Dynamic power management in IoT devices
In recent decades, the increase in demand for low power solutions required the development of new algorithms and clever techniques, which could save energy and guarantee a long-lasting shelf life of a standalone solution powered by batteries. Three key parameters and components of a general electronic solution are the semiconductor, software, and power for operation.…
LoRaWAN in action
In July 2019, a new world record was set when 24 LoRaWAN gateways simultaneously received a message transmitted by a node and one of the gateways was residing at a distance of 766 kilometers from the node. The previous record was 702 kilometers. The new record is set by a team from the University of…
Electro non mechanical relays characteristics and how-to DIY
With the replacement of vacuum tubes by transistors, it became possible to switch between logic states with a minute amount of power consumption and in a relatively smaller space. This article will focus on logic switching. Not much has changed with electrical switching technologies, although there have been some innovations around various techniques to switch…
