In the previous article we put a number on the energy cost of talking to a satellite instead of a ground station. It turns out that NTN registration uses roughly 13 more energy than terrestrial, and an NTN transmission of a 28-byte payload roughly 14 more

Introduction The rapid evolution of the Internet of Things has shifted the focus from mere connectivity to energy sustainability. Microcontrollers such as the ESP32-C6 1, featuring a modern RISC-V architecture and advanced wireless capabilities (Wi-Fi 6,

NTN, Non-Terrestrial Network, gets a lot of attention in the IoT space right now, and for good reason. Think of wildfire sensors deep in a forest, offshore monitoring buoys, or remote pipeline sensors where there is simply no cellular coverage. For those

It's a natural assumption: put in twice as many batteries and get twice the battery life. But is it actually true? For IoT and electronics projects, form factor is often a critical constraint that doesn't always leave room for additional batteries. On the

Otii software 3.7 introduces new features that address one of the most important and often guessed aspects of embedded development: figuring out how long your battery will really last. For engineers working on battery-powered devices, this update makes it

When working with battery-powered cellular IoT devices, low-power modes like PSM (Power Saving Mode) and eDRX (Extended Discontinuous Reception) are typically enabled by default. While most cellular modules support these features, developers often assume

The challenge of low-power cellular IoT development Developing battery-powered IoT devices with cellular connectivity presents an engineering challenge: understanding exactly where and when power is consumed during cellular network events. While power mea

Designing reliable energy-harvesting systems requires more than reading datasheets; it requires understanding how a supercapacitor behaves in real applications. To make informed design decisions, it's important to combine theoretical knowledge with practi

Cellular IoT standards such as LTE-M and NB-IoT offer power-saving features, such as PSM and eDRX, that, when configured correctly, can significantly extend battery life. Understanding how these modes behave and measuring their real timing and current-con

One frequently asked question concerns the expansion port on the Otii Arc and Otii Ace, specifically the GPIO pins and how they can be used for power measurement. We thought we'd give you a few examples of their use! Control the start/stop of the power me
