Maxbotix Ultrasonic Rangefinder - LV-EZ1

Ultrasonic rangefinder detecting objects from 0 to 254 inches (6.45 m) with 1-inch resolution beyond 6 inches. Outputs pulse width, analog voltage (Vcc/512 V/inch), and 9600 baud serial.

BW1
Pin 1. Leave open or hold low for serial output on TX; hold high for pulse output on TX for low-noise chaining.
Type · controlVoltage · Logic level is 0-Vcc, per LV-MaxSonar-EZ datasheet.
PW2
Pin 2. Pulse-width range output; distance scale factor is 147 us per inch.
Type · signal
AN3
Pin 3. Analogue voltage range output corresponding to the most recent range data.
Type · analogueVoltage · Scale factor is Vcc/512 volts per inch, about 9.8 mV/in at 5 V or 6.4 mV/in at 3.3 V.
RX4
Pin 4. Range-command input. Left unconnected or held high for continuous ranging; hold low to stop ranging; bring high for 20 us or more to command a reading.
Type · controlVoltage · Internally pulled high, logic level follows Vcc.
