基板サイズ:3.2cm × 1.4cm

LM393 コンパレータ搭載

使用説明

フォトレジスタモジュールは周囲の光の強さに敏感で、一般的に環境光の明るさを検出し、マイコンやリレーモジュールのトリガーとして使用されます。

環境光の強さが設定されたしきい値より低い場合、DO端子はHighレベルを出力します。
環境光が設定値を超えると、DO端子はLowレベルを出力します。

DO出力端子はマイコンに直接接続でき、High / Lowレベルを検出することで環境光の変化を判断できます。

DO端子はリレーモジュールを直接駆動することもでき、光制御スイッチとして利用可能です。

AO端子はアナログ出力で、ADモジュールやマイコンのアナログ入力と接続することで、環境光の強さをより正確な数値として取得できます。
