About this item

The Digilent Pmod MAXSONAR is a compact ultrasonic range-finder module featuring the MaxBotix LV‑MaxSonar‑EZ1 sensor, designed to detect objects within a range of 6 inches to 255 inches (approximately 15 to 648 cm) with 1-inch resolution. It offers three output formats—analog voltage (proportional to distance at ~6.4 mV/inch), pulse-width modulation (147 µs per inch), and serial UART (9600 baud, ASCII format)—making it compatible with a wide range of embedded systems. The sensor initializes in about 250 milliseconds, performs a self-calibration in 49 milliseconds, and provides distance readings approximately every 50 milliseconds in continuous mode, equating to a sampling rate of about 20 Hz. Compact in size, the module measures just 0.9 × 0.8 inches (2.3 × 2.0 cm), and connects via a standard 6-pin Pmod interface. It operates on a power supply range of 2.5V to 5.5V, with 3.3V recommended for most applications. The Pmod MAXSONAR is well-suited for robotics, automation, obstacle detection, proximity sensing, and distance measurement applications. With multiple data output modes and reliable performance, it is a versatile and valuable tool for engineers and developers working with FPGAs or microcontrollers in embedded system design and prototyping.
