Feasibility of power management for an autonomous, in-field device
For a global manufacturer of environmental sound and vibration monitoring equipment
Challenge
Our customer wanted to develop a new in-field device that could be left in remote locations to monitor sound pressure levels for longer, extended periods and collect more data.
They had a concept in mind and engaged Consult Red to scope, design and develop their low-power solution and test that it could transmit the environmental sound data from a remote location, using just solar power to extend the in-field operation of the in-built Li-ion cells.
Solution
The solution required comprehensive research and selection of components, establishing an end-to-end data path, and integrating solar power for battery recharging. It included the specification of both hardware and software architectures, with a focus on assessing audio data compression and evaluating Wi-Fi and cellular options for data communication.
A proof of concept was developed, followed by rigorous field testing to validate the design. The project also prioritised design for volume manufacturing, ensuring that the technology was tailored for consumer markets. Throughout the process, compliance with worldwide standards for hardware and software was maintained.
Learnings
The resulting technology demonstrated the improved capabilities for environmental monitoring and provided a real-world understanding of power needs and recharging in a difficult climate such as the UK.
We brought our experience in sensing, data communications, data compression, power management and solar charging to innovate power management capability for stand-alone devices in remote locations.
