紅外傳感器 (循迹 / 避障 / 測距) IR Obstacle Avoidance Sensor

$15.00

商品說明

此傳感器模塊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。

 

參數說明
當模塊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。

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。

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

比較器採用LM393,工作穩定;

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;

具有3mm的螺絲孔,便於固定,安裝;

電路板尺寸:3.2c m * 1.4 cm

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
2 GND外接GND
3 OUT小板數字量輸出接口(0和1)

 

 

The sensor module adaptable to ambient light, having a pair of infrared emitting and receiving tubes, transmitting tubes emit infrared certain frequency, when the direction of an obstacle is detected (reflection surface), the infrared reflected is received by the reception tube, After a comparator circuit processing, the green light is on, but the signal output interface output digital signal (a low-level signal), you can adjust the detection distance knob potentiometer, the effective distance range of 2 ~ 30cm, the working voltage of 3.3V- 5V. Detection range of the sensor can be obtained by adjusting potentiometer, with little interference, easy to assemble, easy to use features, can be widely used in robot obstacle avoidance, avoidance car, line count, and black and white line tracking and many other occasions.
Module Parameters
When the module detects an obstacle in front of the signal, the green indicator lights on the board level, while the OUT port sustained low signal output, the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases; counterclockwise adjustment potentiometer, reducing detection distance.
The sensor active infrared reflection detection, target reflectivity and therefore the shape is critical detection distance. Where the minimum detection distance black, white, maximum; small objects away from a small area, a large area from the Grand.
The sensor module output port OUT port can be directly connected to the microcontroller IO can also be directly drive a 5V relay; Connection:
Vcc – Vin
Vgnd Ground- ;
Vout – Signal Out
M393, stable;
The module can be 3-5V DC power supply. When the power is turned on, the red power indicator lights;
Board size: 3.2CM * 1.4CM
Each module has been shipped threshold comparator voltage adjusted by potentiometer good, non-special case, do not adjustable potentiometer.
Module Interface Description
1 VCC 3.3V-5V external voltage (can be directly connected to 5v and 3.3v MCU MCU)
2 GND GND External
3 OUT small board digital output interface (0 and 1)
