Smart Car Obstacle Avoidance Sensor Module Measuring Distance Infrared Sensor Photoelectric Switch Module

Feature: 1. Inductive object output 0, output 1 when not sensed, can be directly connected to 3V and 5V microcontroller IO port. 2. The sensing distance is 2 to 40 cm, the distance is long, and the anti-interference ability is good. (Note: Infrared sensors do not detect all objects to get the same distance. Objects of different colors have different reflectivity to light. The darker the object (closer to black) the shorter the distance detected. 2 to 40 cm is Measured through a white wall) 3. Fast speed, suitable for intelligent car obstacle avoidance, black and white line tracking, anti-drop, product counter, line cutting, liquid level detection, etc. 4. The black and white line tracing car made with this sensor does not need to run on the white paper black line, and can be patrolled in the complex environment black line such as cement floor and yellow mud. As long as the color around the black line is slightly lighter than black, the traditional way of walking is eliminated, making the environment more simple. 5. This sensor is powered by 3 to 6V, suitable for 3V and 5V MCU systems. 6. With the enable terminal, the sensor does not work when the EN terminal is equal to "1" and it works when it is equal to "0". After the jumper cap is inserted on the sensor, the EN terminal is grounded always (EN is "0" for a long time). Please remove the jump cap when using the EN end. 7. The frequency adjustment potentiometer is used to adjust the carrier frequency of the infrared transmitting tube because the integrated receiving head is the most sensitive at a specific 38 kHz carrier frequency. Turn the 502 resistor clockwise (that is, adjust the brightness of the tube to the maximum) then align the white wall with the 103 resistor, and adjust until the sensing distance is the farthest, so the sensor works at its best.
