Speed Sensor On The Radio
Description:
This is a speed module for smart car, which adopted the Groove radio photoelectricity. As long as it can go through the nontransparent objects,
the Groove (with the disk from the shop in use together)will be triggered to output 5V TTL .
Pulses with Schmitt trigger debounce, very stable, can be used to measure the speed, to survey the distance, and perform other functions.
Four pins are defined as +5 GND OUT1 OUT2,among which OUT1 OUT2 perform as level output. You can directly plug into MCU IO port, with LED indicating the output status.
Parameter:
- Using chips:74HC14D
- Operating Voltage:3.3V - 5V
- Output Mode:Digital signal (pulse signal)
- Detection method:Infrared rays Interrupt
- Detection signal:Obstacle is detected is high, no obstacle or exceeds the detection range output low
- LED:Two Status LEDs ray interrupt indicator is off, turn indicator light rays
