HC-SR04 Ultrasonic sensor module Distance Measuring Transducer Sensor for Arduino
Description:
1. HC-SR04 ultrasonic module can offer non-contact distance sensing function;
2. includes ultrasonic transmitter, receiver and control circuit.
3. Operation requirement: Take IO port TRIG to trigger ranging.
It needs 10 us high level signal at least
4.Operating principle :
can send 8 pro 40 kz square wave automatically, and will test if there is any signal returned.
If there is signal returned, output one high level signal via IO port ECHO.
The duration of the high level signal is the time from transmitter to receiving with the ultrasonic.
Main technical parameters:
1. voltage: DC5V
2. static current is less than 2mA
3. output: high4: low level output:5V
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.
