Details: Description:
The module has stable performance and accurate distance measurement:
Comparable with SRF05, SRF02 ultrasonic distance measurement modules, etc. Module accuracy, blind spot (2 cm) is super close, stable range, this product is launched to the market under the strong!

Features:
Voltage: DC5V
Static Current: Less than 2mA
Level Output: High 5V
Level Output: 0V End
Sensor Angle: No Over 15 degrees
Detection distance: 2cm-450cm
High precision: up to 0.3cm
Connections: VCC, TRIG (control side), echo (receiver side), GND

Uses:
10 cents to control the population over a high fat, you can wait to receive a high output port. A timer can be turned on by the output timing, when the port goes low, only the distance is calculated when the timer value can read the time for this distance. With this constant cycle measurement, you can reach the value of cell phone measurements.
Module works:
IO trigger position, to at least 10 us high signal.
The module automatically sends eight 40khz square waves and automatically detects whether the signal is returned.
Return signal, through high output IO, high duration
ultrasonic time from launch to return. Test Distance = (Time * High Speed Sound (340M/S)) /
This module provides a full range of procedures: C51, PIC18F877, Ultrasonic LCD1602 Display, Ultrasonic LCD12864 Display, LED Display, Serial Display, Range Reference Program.

Package Dimensions: 12x114x11
