Maxbotix Ultrasonic Rangefinder - LV-EZ1
LV-EZ1 Maxbotix Ultrasonic Rangefinder provides very short to long-range detection and ranging, in an incredibly small package.
Pinout
- 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.
