描述
紅外線避障模組 避障/近接開關/感應距離可調 最長反射距離 30CM
紅外線避障模組 對環境光線適應能力強,其具有一對紅外線發射與接收管,發射管發射出一定頻率的紅外線,當檢測方向遇到障礙物(反射面)時,紅外線反射回來被接收管接收,經過比較器電路處理之後,綠色指示燈會亮起,同時信號輸出接口輸出數字信號(一個低電平信號),可通過電位器旋鈕調節檢測距離,有效距離範圍2~30cm,工作電壓為3.3V- 5V。該傳感器的探測距離可以通過電位器調節、具有乾擾小、便於裝配、使用方便等特點,可以廣泛應用於機器人避障、避障小車、流水線計數及黑白線循蹟等眾多場合。
模塊參數說明
1 當 紅外線避障模組 檢測到前方障礙物信號時,電路板上綠色指示燈點亮電平,同時OUT端口持續輸出低電平信號,該模塊檢測距離2~30cm,檢測角度35°,檢測距離可以通過電位器進行調節,順時針調電位器,檢測距離增加;逆時針調電位器,檢測距離減少。
2、傳感器主動紅外線反射探測,因此目標的反射率和形狀是探測距離的關鍵。其中黑色探測距離最小,白色最大;小面積物體距離小,大面積距離大。
3、傳感器模塊輸出端口OUT可直接與單片機IO口連接即可,也可以直接驅動一個5V繼電器;連接方式:VCC-VCC;GND-GND;OUT-IO
4、比較器採用LM393,工作穩定;
5、可採用3-5V直流電源對模塊進行供電。當電源接通時,紅色電源指示燈點亮;
6、具有3mm的螺絲孔,便於固定、安裝;
7、電路板尺寸:3.2CM*1.4CM
8、每個模塊在發貨已經將閾值比較電壓通過電位器調節好,非特殊情況,請勿隨意調節電位器。
模塊接口說明
1 VCC 外接3.3V-5V電壓(可以直接與5v單片機和3.3v單片機相連)
2 GND 外接GND
3 OUT 小板數字量輸出接口(0和1)
