XL-MaxSonar-EZ0 MB1200 Ultrasonic Distance Sensor
Compact ultrasonic sensor with a wide, sensitive beam for indoor use, offering reliable detection and real-time calibration. Operates on 3.3–5.5V.
Pinout
- Pin 1MB1200 datasheet pin 1
Leave open or high for serial output on Pin 5; hold low for Pin 5 pulse output suitable for low-noise chaining.
Type · ControlVoltage · 0-Vcc logic, Vcc is 3.3V to 5V - PWMB1200 datasheet pin 2
Pulse-width range output on MB1200. Datasheet scale factor is 58 µs per cm.
Type · GPIOVoltage · 0-Vcc logic, Vcc is 3.3V to 5V - ANMB1200 datasheet pin 3
Analog voltage range output, scaling factor Vcc/1024 per cm. Buffered output for most recent range data.
Type · AnalogVoltage · Vcc/1024 per cm; about 4.9 mV/cm at 5V and 3.2 mV/cm at 3.3V - RXMB1200 datasheet pin 4
Ranging control input. Internally pulled high; left open or high keeps measuring, held low stops ranging. Bring high for 20 µs or more for a range reading.
Type · UARTVoltage · 0-Vcc logic, internally pulled high - TXMB1200 datasheet pin 5
Asynchronous serial range output when Pin 1 is open/high: ASCII R plus three range digits in cm plus carriage return, 9600 baud 8N1. Sends a pulse when Pin 1 is held low.
Type · UARTVoltage · 0-Vcc serial-level output, not true RS232 voltage - V+MB1200 datasheet V+ pad
DC supply input for the XL-MaxSonar MB1200 sensor.
Type · PowerVoltage · 3.3V to 5V; average current 2.1 mA at 3.3V or 3.4 mA at 5V, higher peak during sonar transmit - GNDMB1200 datasheet GND pad
Return for the DC power supply. Datasheet says GND and V+ must be ripple and noise free for best operation.
