TECNOIOT 5pcs Infrared Slotted Optical Speed Sensor Detection Optocoupler Module
TECNOIOT 5pcs Infrared Slotted Optical Speed Sensor Detection Optocoupler Module
X5pcs Infrared Slotted Optical Speed Measuring Sensor Detection Optocoupler Module The slot type photoelectric sensor is composed of an infrared light emitting diode and an NPN phototransistor with a groove width of 5.9 mm. As long as the non-transparent object passes through the slot type, it can be triggered (used with the shop's car code wheel) to output TTL low level. The Schmitt trigger is used to shake the pulse, which is very stable and can be used for measuring the speed of the car, measuring the distance and the like! M3 screw mounting holes at both ends. Specifications: Working voltage: 3.3V-5V. Output form: digital switch OUT output (0 and 1) When VCC and GND are connected, the module signal indicator will be on. When there is no block in the module slot, the receiving tube is turned on, and the module OUT outputs high level. When blocking, the OUT output is low and the signal indicator is off. The module OUT can be connected to the relay to form a limit switch and other functions, and can also be connected to the active buzzer module to form an alarm. The OUT output interface can be directly connected to the IO port of the MCU. Generally, it is connected to an external interrupt to detect whether the sensor has an occlusion. For example, the motor code wheel can detect the motor speed. Package contains: 5pcs x IR Infrared Slotted Optical Speed Measuring Sensor Detection Optocoupler Module
Product Features
- Optional IR speed: Optocoupler module for detecting the slotted optical speed measuring sensor with infrared. The slit photograph consists of an infrared light-emitting diode and an NPN phototransistor with a gap width of 5.9 mm. As long as the non-transparent object passes the slot type, it can be activated (used with the store encoder wheel) to produce a low TTL level.
- Technical data: Operating voltage: 3.3 V-5 V. Output format: digital switching output (0 and 1). When VCC and GND are connected, the signal indicator of the module lights up. When freezing, the OUT output is low and the signal indicator is off. The OUT module can be connected to the relay to form a limit switch and other functions, and can also be connected to the active buzzer module to form an alarm.
- Programming: The OUT output interface can be directly connected to the IO port of the MCU. Normally connected to an external interrupt to detect if the sensor has occlusion. For example, the encoder wheel of the motor can detect the engine speed. The OUT port of the speed measuring module is connected to the external interrupt port of the MCU. Whenever infrared rays are directed, it is an external buffer.
- MeasurementMeasurement distance: the output of the speed sensor is a pulse signal, a pulse is interrupted once; the infrared beam is weak when activated, so we set the interrupt to the low-level touch mode. SPEED MEASUREMENT: According to the idea of distance measurement, we use MCU timer to calculate the number of external interrupts received in one second.
- Precautions: Correct wiring. Do not interchange plus and minus so that the electronic components of the board are burned. Arduino readers must put the MCU I/O port into input/receive mode, otherwise they will not be available. Other MCUs or more advanced control boards need to be set to input/receive mode when the I/O port needs to be set to input/output mode, Otherwise it cannot be used.
