Usage

const { DecibelMeter } = require('pcb-artists-decibel-meter');

(async () => {
    const device = new DecibelMeter();

    while (true) {
        const db = await device.readDecibel();
        const minDb = await device.readMin();
        const maxDb = await device.readMax();

        console.log(`Decibel: ${db} dB, Min: ${minDb} dB, Max: ${maxDb} dB`);

        await new Promise((r) => setTimeout(r, 1000));
    }
})();

const { DecibelMeter } = require('pcb-artists-decibel-meter');

(async () => {

    await device.clearHistory();

    while (true) {
        const history = await device.readHistory();
        console.log('Decibel History:', history);
        await new Promise((r) => setTimeout(r, 1000));
    }
