Specification:
Item Type: Ultrasonic Distance Measuring ModuleMaterial: Synthetic cardboard
Purpose: Accurate ranging, suitable for MCU development board
Operating Voltage: DC 5V
Working Frequency: 40KHz
Working Current: 15mA
Level Output: 05V
Induction Angle: less than 15 degrees
Range: Approx. 2cm4meter 0.8in13.1ft (peak)High Accuracy: Up to approx. 0.3cm 0.1in
Blind Area: Approx. 2cm 0.8in
Trigger Input Signal: 10uS TTL pulse
Output Echo Signal: Output TTL level signal, proportional to range
Board Wiring Mode: VCC (input), Trig (control terminal), Echo (receiving terminal), GND (ground)
How to Use This Product: A control port sends a high level above 10US, and you can wait for the high level output at the receiving port. Once there is an output, you can start the timer to count, and when the port becomes low, you can read the timing The value of the device, at this time, is the time of this ranging to calculate the distance. Such continuous periodic measurement can get the value of your mobile measurement
The Working Principle of Module:
(1) Use IO to trigger the ranging and give a high level signal of at least 10us;
(2) The module automatically sends 8 40khz square waves and automatically detects whether there is a signal return;
(3) There is a signal return, and a high level is output through IO. The duration of the high level is the time from the ultrasonic wave to the return. Test distance = (high level time x speed of sound (340ms))2.
