Efficiency and Performance


How the Indium Works

the Indium series, our state-of-the-art solar energy harvesting solutions designed to provide efficient power management for IoT sensor systems. The Indium series includes three versions: PowerBoost, PowerMax, and PowerEase, each tailored to meet diverse energy requirements and integration preferences.

At its core, the Indium system leverages solar energy intelligently to significantly extend the lifespan of sensors, minimize their power demands, and reduce overall operational costs, all while contributing to environmental sustainability.

Indium integrates seamlessly with existing sensors, allowing sensor manufacturers to enhance their products without having to invest in significant power management implementation. While the PowerBoost and PowerMax versions allow for more invasive integration, providing sensor companies with more control, the PowerEase version stands apart with its unique feature – an onboard Microcontroller Unit (MCU).

Indium Versions

Whether you need an external version of the indium or within your enclosure, or for that matter, on your existing PCB, Element 4 Provides three versions, based on your power requirements, level of control, environment and ease of implementation.


Indium PowerBoost

Focused on offsetting power-intensive transmission events, PowerBoost is engineered for sensor systems where transmission events drive the majority of power consumption.


Indium PowerMax

An advanced energy harvesting solution, PowerMax powers both the transmission events and the entire sensor system. This version is designed for sensor systems with moderate power consumption operating in environments abundant in ambient energy sources.


Indium PowerEase

A user-friendly, non-invasive approach to energy harvesting, PowerEase includes a proprietary MCU that monitors and manages power availability during transmission events. This version is the perfect choice for clients looking for an easy-to-integrate, non-invasive solution.

Each version of the Indium Power Pack Solution is testament to Element 4’s commitment to delivering flexible, efficient, and user-friendly power harvesting solutions. Choose the Indium version that aligns best with your needs, and experience the benefits of our cutting-edge energy harvesting technology.
