HRLV

HRLV-MaxSonar-EZ sensor #

The high resolution HRLV‑MaxSonar‑EZ senors are high performance ultrasonic sensors with noise rejection, improved automatic calibration, and factory calibrated beam patterns. The HRLV‑MaxSonar‑EZ sensors have three outputs: Analog Voltage, Pulse Width, RS232 or TTL serial data.
