Arduino power management library for IoT energy optimization

IoT and wearable devices have become essential tools in our daily lives. From health-monitoring wearables to smart home sensors, they rely heavily on battery power to operate. However, optimizing energy consumption without compromising performance remains one of the most important obstacles for developers. Constant power drain can lead to shorter battery life, frequent charging, and limited functionality, which ultimately frustrates users and shortens the lifespan of devices.

As IoT and wearable devices become more advanced, they also become more energy-hungry. Constantly running sensors, wireless communications, and processing tasks consume batteries faster than ever. In many cases, consumers expect their devices to last for days, weeks, or even months on a single charge. A device that needs to be charged frequently or loses performance due to inefficient power consumption may result in a poor user experience.

New Arduino power management library

For developers, solving these problems can be a time-consuming and demanding process, especially when balancing performance with energy efficiency. Developers often have to spend a lot of time tuning power settings, writing custom code, and manually controlling various components to reduce power consumption. Without the right tools, energy optimization can become a bottleneck in product development.

How the new Arduino power management library solves the problem

Arduino recognized the need for a simple but efficient solution to this problem and responded by developing a new power management library. Designed specifically for Arduino Pro modules such as Portenta H7, Portenta C33 and Nicla Vision, this library allows developers to easily manage power consumption without sacrificing functionality.

With features such as sleep and standby modes, real-time battery monitoring, and adjustable charging parameters, this library provides a range of tools to improve the energy efficiency of IoT and wearable devices. Developers can now monitor key battery metrics, switch power rails, and even enable deep sleep modes, where some devices use less than 100 microamps. Thanks to this, devices can operate for months or even years on a single charge.

Battery monitoring and status tracking

One of the most important aspects of managing IoT and wearable devices is closely monitoring battery health and usage. The Arduino power management library provides real-time visibility into key battery metrics, including voltage, current draw, temperature and battery percentage. These data points are crucial for optimizing energy use, identifying potential problems, and ensuring your devices last as long as possible.

By tracking battery health and capacity, developers can extend the life of their devices, reduce the risk of unexpected shutdowns, and prevent overheating. Additionally, the library can predict charging and discharging times, which helps developers optimize charging cycles and power management strategies.

Charging control for longevity

Another standout feature of the power management library is its ability to give developers precise control over battery charging. For devices powered by LiPo batteries, proper charging management is essential to maintain long-term health and avoid battery damage. The library supports monitoring all three stages of LiPo battery charging – pre-charge, constant current and constant voltage. It also allows you to adjust parameters such as charging voltage and charging current.

This check ensures that batteries are charged in the safest and most efficient manner, extending their lifespan and ensuring the reliability of your IoT or mobile device for years to come.

Optimized energy saving modes

The Power Management Library introduces two critical low-power modes: sleep and standby. These modes drastically reduce power consumption while still allowing the device to operate. In sleep mode, the module continues to operate but at a much lower power level, ensuring a quick wake-up when needed. In standby mode, the device’s power consumption drops to a minimum, making it ideal for long-term applications such as remote sensors or sparse data loggers.

Developers can also control which peripherals remain active and which are disabled in these low power modes, further reducing unnecessary power consumption. This level of granular control helps you balance energy savings with performance, so your devices run longer on battery power.

Tuning the power rails

Another key feature of the library is the ability to tune the power rails on Arduino boards. Developers can switch voltages on different power rails, optimizing power consumption for specific tasks or components. This level of customization allows developers to target specific areas of their devices’ power consumption, allowing them to maximize performance.

In today’s rapidly growing IoT and mobile device market, energy efficiency is a key factor in product differentiation. Arduino’s new power management library gives developers the tools they need to reduce power consumption, extend battery life, and increase performance across a variety of devices. From advanced battery monitoring to precise control over charging and power saving modes, this library simplifies the process of creating energy-efficient devices. By adopting these features, developers can ensure that their IoT devices and wearables not only perform better, but also last longer and require less maintenance.
