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 be
