With 2.5V - 5.5V power the LV-MaxSonar-EZ provides very short to long-range detection and ranging in a very small package. The LV-MaxSonar-EZ detects objects from 0-inches to 254-inches (6.45-meters) and provides sonar range information from 6-inches out to 254-inches with 1-inch resolution. Objects from 0-inches to 6-inches typically range as 6-inches1. The interface output formats included are pulse width output, analog voltage output, and RS232 serial output. Factory calibration and testing is completed with a flat object.

Features
• Continuously variable gain for control  and side lobe suppression
• Object detection to zero range objects
• 2.5V to 5.5V supply with 2mA typical current draw
• Readings can occur up to every 50mS, (20-Hz rate)
• Free run operation can continually  measure and output range information
• Triggered operation provides the range  reading as desired
• Interfaces are active simultaneously
• Serial, 0 to Vcc, 9600 Baud, 81N
• Analog, (Vcc/512) / inch
• Pulse width, (147uS/inch)
• Learns ringdown pattern when commanded to start ranging
• Designed for protected indoor environments
• Sensor operates at 42KHz
• High output square wave sensor drive(double Vcc)
• Actual operating temperature range from –40°C to +65°C, Recommended
   operating temperature range from 0°C to +60°C 1

Benefits
