The module can detect the distance of 2-30cm and detect the distance of 35 detection angle, and 1° to detect obstacles in front of the signal, board level green indicator light. Potentiometers can detect the clockwise adjustment potentiometer to adjust distance increase. Anti-clockwise adjustment potentiometer to reduce detection distance
As shown in Figure 2, the sensor is active infrared reflection detection, objective reflectivity, and therefore the shape is critical detection distance. Here, minimum detection distance black, white, max. Small areas and objects far away from the ground
As shown in Figure 3, the output port of the sensor module OUT port can directly connect the IO to a microcontroller that can drive a 5V relay. Connection: VCC-VCC;GND-GND;OUT-IO
Figure 4 is LM393, stable comparator.
As shown in Figure 5, the module can be 3-5V DC power supply. Red power indicator lights up when power on.
As shown in Figure 6, the screw hole is 0.1 inch (3 mm) for easy fixing equipment.
7. Board Size: 1.3 x 0.6 inches (3.2 x 1.4 cm).
As shown in Figure 8, each module performs a non-specialized case potentiometer. Threshold comparison voltage, which has been shipped unadjustable potentiometers.
