Compact ultrasonic rangefinder detecting objects from 0 to 254 inches (6.45m), with reliable ranging from 6 inches at 1-inch resolution. Outputs pulse width, analog voltage (Vcc/512 V per inch), and 9600-baud serial.
Pin 1, leave open or hold low for serial output on TX; hold high to make TX output a pulse for low-noise chaining, per MaxBotix LV-MaxSonar-EZ datasheet.
Pin 2 pulse-width range output, 147 us per inch, per MaxBotix LV-MaxSonar-EZ datasheet.
Pin 3 analogue range output, scaled at Vcc/512 volts per inch and buffered to the most recent range data.
Pin 4 ranging control input. Internally pulled high; left unconnected or held high for continuous ranging, held low to stop ranging, pulse high for 20 us or more to command a reading.
Pin 5 serial output when BW is open/low: ASCII R plus three range digits and carriage return at 9600 baud, 8N1; sends a pulse instead when BW is high.
Pin 6 Vcc supply for the LV-MaxSonar-EZ sensor.
Pin 7 DC power-supply return; datasheet notes GND and Vcc should be ripple and noise free for best operation.
