deciBLE is built on common tools. It’s a simple device, with all the components it needs and nothing it doesn’t. At its core, a Cortex M0 runs the show at a power-saving 48MHz. This central processor orchestrates everything from sensor data acquisition to radio communications. Some things, like Bluetooth radio, are handled by secondary systems. For this, the central core has a dedicated hardware link connecting both chips, enabling a two-way data stream for reliable performance.
The most sensitive part of deciBLE is the microphone, measuring the environment with a 60dB bias. The raw signal from the microphone is used to measure the average sound intensity. A high fidelity data processing technique filters the raw data into an accurate reading of the nearby sound level.
There’s also an onboard battery with a power management circuit. This allows you to charge by USB or operate independently for up to one week of continuous coverage.
