Maxbotix Ultrasonic Rangefinder - HRLV-EZ4
High-resolution ultrasonic rangefinder with 1mm resolution, detecting objects from 1mm to 5m (ranging reliable from 30cm). Outputs pulse width, analog voltage, and serial (RS232 or TTL selectable via solder jumper).
Pinout
- Pin 1 BW1
Beam-width / calibration control pin from the HRLV-MaxSonar-EZ datasheet linked by the Adafruit HRLV-EZ4 product page.
Type · control - Pin 2 PW2
Pulse-width range output from the HRLV-MaxSonar-EZ datasheet linked by the Adafruit HRLV-EZ4 product page.
Type · signal - Pin 3 AN3
Analogue voltage range output from the HRLV-MaxSonar-EZ datasheet linked by the Adafruit HRLV-EZ4 product page.
Type · signal - Pin 4 RX4
Serial receive / control input from the HRLV-MaxSonar-EZ datasheet linked by the Adafruit HRLV-EZ4 product page.
Type · signalVoltage · Adafruit product page states default serial output is RS-232 logic level; TTL mode requires soldering the square jumper closed. - Pin 5 TX
