Maxbotix Ultrasonic Rangefinder - LV-EZ0

LV-EZ0 Maxbotix Ultrasonic Rangefinder provides very short to long-range detection and ranging, in an incredibly small package.

BW1
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.
Type · control
PW2
Pin 2 pulse-width range output, 147 us per inch, per MaxBotix LV-MaxSonar-EZ datasheet.
Type · signalVoltage · 0-Vcc pulse-width output
AN3
Pin 3 analogue range output, scaled at Vcc/512 volts per inch and buffered to the most recent range data.
Type · analogVoltage · 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 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.
