HRLV-MaxSonar-EZ Series Ultrasonic Rangefinder Product Description
The HRLV-MaxSonar-EZ sensor line is the most cost-effective solution for applications where precision range-finding, low-voltage operation, and low-cost are needed. This sensor component module allows users of other more costly precision rangefinders to lower the cost of their systems without sacrificing performance.

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 are typically reported as 30-cm. The interface output formats are pulse width, analog voltage, and serial digital in either RS232 or TTL.

Precision Range Sensing
? Range-finding at a fraction of the cost of other precision rangefinders
? Reading-to-reading stability of 1-mm at 1-meter is typical
? Accuracy is factory-matched at 1-meter to 0.1% providing a typical large target accuracy of 1% or better for most voltages and uses 
? Calibrated acoustic detection zones allows selection of the part number that matches a specific application
? Compensation for target size variation and operating voltage range
? Standard internal temperature compensation and optional external temperature compensation

Range Outputs
? Pulse width, (1uS/mm)
? Analog Voltage, (5mm resolution)
? Serial, (RS232 or TTL using solder-able jumper or volume orders available as no- cost factory installed jumper)

Easy to Use Component Module
? Gracefully handles other ultrasonic sensors 
? Stable and reliable range readings and excellent noise rejection make the sensor easy to use
? Easy to use interface with distance provided in a variety of outputs
? Target size compensation provides greater consistency and accuracy when switching targets
? Sensor automatically handles acoustic noise
? Sensor ignores other acoustic noise sources
? Small and easy to mount
? Calibrated sensor eliminates most sensor to sensor variations
?  Very low power ranger, excellent for multiple sensors or battery based systems

General Characteristics
? Low-cost ultrasonic rangefinder
? Size less than 1 cubic inch with easy mounting
? Object proximity detection from 1-mm to 5-meters
? Resolution of 1-mm
? Excellent 3 Mean Time Between Failure (MTBF)
? Triggered operation yields a real-time
? 100mS measurement cycle
? Free run operation uses a 2Hz filter, with 100mS measurement and output cycle
? Actual operating temperature range from -40°C to +65°C, Recommended operating temperature range from -15°C to +65°C, provided proper frost prevention is employed
? Operating voltage from 2.5V to 5.5V
? Nominal current draw of 2.5mA at 3.3V, and 3.1mA at 5V
? Low current draw reduces current  drain for battery operation
? Fast first reading after power-up eases battery requirements
