Cost Saving DC5V Ultrasonic Module HC-SR04 Example

Specifications

1. Low Prices Direct From Factory Suppliers.

2. High Quality With Global Standards.

Description:

This module performance and stability, accurate measurement of distance. Can and foreign SRF05, SRF02comparable ultrasonic ranging module.Module of high precision, blind area (2cm ) super close, stable range is the success of this product to market the strong basis!

Main technical parameters:

1. Voltage: DC5V

2. Static current is less than 2mA

3. Output: high

4: Low level output: 5V0V

5. Induction angle: not more than 15 DEG

6. Detecting distance: 2cm-450cm

7. High precision: up to 3mm

Connection mode, VCC, trig ( control side), echo ( receiver ), GND wire

This product use: a control orifice with a 10US above high level, can be in the receiving port to wait for high level output. The output of the timer can be opened, when the orifice is low we can read the timer value, this time for the ranging time,We can calculate the distance. So continuous cycle test, can achieve your mobile measurement value.

Module working principle:

(1) using IO trigger location, to at least10us high level signal;

(2) module to automatically send8 40KHz square wave, to automatically detect whether a signal return;

(3) a return signal, through the IO outputs a high level, high level for a time is Ultrasonic wave from the transmitter to the return time. Testing distance = ( high level time * speed of sound (340M/S ) ) /2.
