## Description

The MB1009 ParkSonar-EZ-144 is an ultrasonic proximity and range sensor from MaxBotix, designed to detect vehicles within a calibrated detection zone. It reports when a target enters or leaves the zone, with both proximity and range data available via logic-level (high/low) and RS232 serial outputs. With a 42 kHz ultrasonic transducer, 25 mm (1-inch) resolution, and a detection zone of approximately 3.7 m (12 ft), the sensor supports automatic multi-sensor operation with 14+ simultaneous units depending on mounting and environment. Key Features Vehicle Detection – Calibrated proximity zone reports target entry and release 25 mm Resolution – 1-inch measurement accuracy 3.7 m Detection Zone – Approximately 12 ft (144 inches) proximity range Maximum Range – 6.45 m (254 inches / 645 cm) Dual Output – Logic level (high/low) and RS232 serial Multi-Sensor Support – Automatic operation with 14+ simultaneous sensors Low Power – 2.0 mA average current draw Wide Voltage Range – 2.5–5.5 V operating voltage Minimal Dead Zone – Objects closer than 150 mm typically read as 150 mm Specifications Sensor Frequency – 42 kHz ultrasonic Operating Voltage – 2.5–5.5 V Average Current – 2.0 mA Target Acquire Time – ~10 seconds Target Release Time – ~5 seconds RoHS Compliant Ideal For Car park occupancy detection systems Vehicle presence sensing Automated parking guidance Industrial proximity detection Resources ParkSonar-EZ-144 Datasheet (PDF)
