Ultrasonic distance sensor (HY-SRF05) with 2channel Logic Level converter Use two GPIO Trig(T) Echo(E) Update –> check distance and update T28 –> Trig use GPIO28 E29 –> Echo use GPIO29 • • • • • • • • Detection distance: 2cm-450cm. High precision: Up to 0.2cm Input trigger signal: 10us TTL impulse Echo signal : output TTL PWL signal Mode of connection: 1.VCC 2.trig(T) 3.echo(R) 4.OUT 5.GND Use method: Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not. The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules. 2 channel Logic Level Converter
: The logic level converter is a small PCB which safely allows you to interface devices which steps down 5V signals to 3.3V signals and step up 3.3V signals to 5V. The converter has 2, inputs and outputs and can be used with I2C, SPI, UART, etc. The board needs to be powered via two sources, 5V and 3.3V and your data lines are linked via pins 1 to 2 on each side so an input on pin 1 will be converted to the lower or higher output on the adjoining pin 1 Download GPIO library https://pypi.python.org/pypi/RPi.GPIO GPIO library – RPi.GPIO-0.5.3a.tar.gz Install python , library and run the test program # sudo apt-get install python-dev # wget http://www.pridopia.co.uk/pi-pgm/RPi.GPIO-0.5.3a.tar.gz GPIO library Ultrasonic sensor module
