Description
10PCS IR Infrared Sensor Module Slotted Optical Optocoupler Speed Measuring Sens. After connecting VCC and GND, the module signal indicator light will light up. When there is no obstruction in the module, the receiver tube will conduct and the module OUT will output a high level; When obstructed, OUT outputs a low level and the signal indicator light goes out.

As long as a non-transparent object passes through the , it can trigger to output a low TTL level. Using Schmidt trigger to jitter pulses is very stable and can be used for small car speed measurement, distance measurement, and other applications! Install holes with M3 screws at both ends. Working voltage: 3.3V-5V, output form: digital switch output (0 and 1) Instructions for use: After connecting VCC and GND, the module signal indicator light will light up. When there is no obstruction in the module , the receiver tube will conduct and the module OUT will output a high level; When obstructed, OUT outputs a low level and the signal indicator light goes out. The module OUT can be connected to a relay to form a limit switch and other functions, and can also be connected to an active buzzer module to form an alarm. The OUT output interface can be directly connected to the IO port of the microcontroller, usually connected to an external interrupt to detect whether the sensor is blocked. If a motor encoder is used, the speed of the motor can be detected. Precautions: Correct wiring! Do not reverse the positive and negative connections to burn out the electronic components of the board. Players should set the I/O port of the MCU to input mode/receive mode, otherwise it cannot be used. Other MCUs, or more advanced control boards such as ARM, must be set to input/output mode if the I/O port needs to be set to input/receive mode, otherwise it cannot be used. The 51 series microcontroller can be used directly without the need to set input and output modes.
