Description: The high resolution HRLV-MaxSonar-EZ sensors are high performance ultrasonic sensors with noise rejection, improved automatic calibration, and factory calibrated beam patterns. These are the best sensors for indoor use, with virtually no dead zone and a resolution of 1 mm!!!

The HRLV-MaxSonar-EZ1 is a great choice for use where sensitivity is needed along with side object rejection. The HRLV-MaxSonar-EZ1 is a good, low-cost starting place for a customer not sure of which HRLV-MaxSonar-EZ sensor to use.

The HRLV-MaxSonar-EZ sensor line provides high accuracy and high resolution ultrasonic proximity detection and ranging in air, in a package less than one cubic inch. This sensor line features 1-mm resolution, target-size and operating-voltage compensation for improved accuracy, superior rejection of outside noise sources, internal speed- of-sound temperature compensation and optional external speed-of-sound temperature compensation.

This ultrasonic sensor detects objects from 1-mm to 5-meters, senses range to objects from 30-cm to 5-meters, with large objects closer than 30-cm typically reported as 30-cm. The interface output formats are pulse width, analog voltage, and serial digital in either RS232 or TTL. Factory calibration is standard.
