1 Module Sensor Ultrasonic Range Finder
Reliable, high performance, high accuracy, blind area within 2cm
Specification
- Voltage:DC5V
- Current:less 2mA
- TTL:higher 5V
- Sensing angle:Less than 15 degree
- Sensing distance:2cm-450cm
- Accuracy:about 0.3cm
- PCB Dimension:4.5*2.0CM
- Connection: VCC, trig(Control), echo(Receive), Out, GND
Working principle
- Send high TTL signal at trigger IO.
- Module automatically send 8*40khz squre wave in order to detect if there are any signal return.
- when signal return, use each(receive) IO pin output high TTL, the output TTL time length is the time from sending till return.
- try to use this fomula: distance = (high TTL time* velocity of sound)/2
- velocity of sound = 340m/s
