B.3 Pin Blue Mini Speed Measurement Sensor
The slot-type photoelectric sensor integrates an infrared light-emitting diode and an NPN phototransistor within its design, featuring a groove width of 5.9 mm. When a non-transparent object passes through the slot, it triggers the sensor, which is commonly utilized in conjunction with our car code wheel. Upon activation, the sensor outputs a TTL low-level signal. To ensure signal stability, a Schmitt trigger is employed to denounce the pulse, resulting in a highly stable output suitable for tasks such as car speed measurement and distance calculation. The module includes M3 screw mounting holes at both ends, facilitating easy installation in various setups.
C.F429 Speed Measurement Sensor
The module operates within a flexible voltage range of 3.3 to 5.5 volts, ensuring compatibility with various power sources. It incorporates an imported groove coupler sensor with a precise groove width of 5mm, enabling accurate detection of objects passing through. When the sensor slots are obstructed, it outputs a high signal and the indicator light remains off; conversely, when there's no obstruction, it outputs a low signal and the light activates. Its output is in the form of digital switching, represented by 0 and 1 states. Utilizing the LM393 comparator output ensures clean signals with excellent waveform characteristics, capable of driving loads exceeding 15mA. Additionally, the module features a fixed bolt-hole for effortless mounting, enhancing its usability across diverse applications.
