LV-MaxSonar-EZ™ modules are in air, ultrasonic non-contact ranging sensors that detect objects within an area. These sensors are not affected by the colour or other visual characteristics of the detected object. Ultrasonic sensors measure the time of flight for ultrasound that has been transmitted to and reflected back from nearby objects. Based on the time of flight, the sensor then outputs a range reading.

• Sensor frequency: 42kHz
• Max reading rate: 20Hz
• Object range: 150 to 6000mm
• Continuously variable gain for control and side-lobe suppression
• Available in five versions with different preset beam- patterns
• Triggered operation provides a single-shot range reading
• Free run operation continually measures and outputs range information
• Output interfaces are active simultaneously
• Output formats: UART serial, Analogue (Vcc/512)/inch, PWM (147μs/inch)
• Learns ringdown pattern when commanded to start ranging
• Multiple sensors can be used in a single system
• Designed for protected indoor environments
• Power supply: +2.5V to +5.5Vdc @ 2mA typical current
• Dimensions: 19.9 x 22.1 x 15.5mm
• Applications: Mobile robot navigation, Collision avoidance, Security
