赤外線障害物検知センサー フォトリフレクタ 光電センサーモジュール Arduino対応 ロボットカー 電子工作用 ka10000a858

品番: ka10000a858
モジュール説明

本モジュールは赤外線反射型障害物検知センサーです。
環境光の影響を受けにくく、赤外線送信管と受信管を搭載しています。

送信側から一定周波数の赤外線を発射し、前方に障害物(反射面)がある場合、反射した赤外線を受信管が検出します。
その信号は比較回路で処理され、障害物を検知すると基板上の緑色LEDインジケーターが点灯し、同時に**OUT端子からデジタル信号(LOWレベル)**が出力されます。

検知距離は可変抵抗(ポテンショメータ)により調整可能で、有効検知距離は約2~30cmです。
動作電圧は3.3V~5Vに対応しています。

本センサーは

ロボットの障害物回避

自律走行ロボットカー

ライン追従(ラインフォロワー)

コンベアラインのカウント検出

などの用途に幅広く使用できます。

モジュール仕様

前方に障害物を検知すると、基板上の緑色LEDが点灯し、
OUT端子からLOWレベル信号が出力されます。

検知距離:約2~30cm
検知角度:約35°

可変抵抗により検知距離の調整が可能です。

時計回り:検知距離が長くなる

反時計回り:検知距離が短くなる

本センサーは赤外線反射方式のため、対象物の反射率や形状によって検知距離が変化します。

黒色物体:検知距離が短い

白色物体:検知距離が長い

また

小さい物体:検知距離が短い

大きい物体:検知距離が長い

OUT出力端子は、

マイコン(Arduino / MCU)のIOポート

5Vリレーの直接駆動

などに接続可能です。

接続方法

VCC → VCC
GND → GND
OUT → MCUのIOポート

比較回路にはLM393コンパレータを採用しており、安定した動作を実現しています。

電源電圧:DC 3~5V

電源投入時、基板上の赤色電源LEDが点灯します。

3mm取付穴を備えており、固定・取り付けが容易です。

基板サイズ

約32mm × 14mm

出荷時に比較電圧(しきい値)は調整済みです。
特別な場合を除き、可変抵抗の調整は行わないでください。

International Shipping Methods

Notes:

  • The billing weight will be based on whichever is greater: the actual weight or the volumetric weight.
  • Volumetric weight (kg) = Length (cm) x Width (cm) x Height (cm) / 5000
  • Common oversized and heavy items include: furniture, fishing rods, automotive parts, etc.
  • Consolidating 2 or more items will incur a "consolidation handling fee" (see price list for details)
    

Platform Transaction Rules:

1. Order cancellations and returns are not accepted for any reason. Please review the item description and seller ratings before purchase.
