Maxbotix Weather-Resistant Ultrasonic Rangefinder

Take your sonar outside - great for all-weather robots! The XL-MaxSonar-WRMA1 ignores smaller targets and only reports the range to target with the largest acoustic return.

Pin 11
Mode select. Leave open/high for asynchronous serial output on TX; hold low for pulse output on TX suitable for low-noise chaining.
Type · control
Pin 22
For MB7092 this pin outputs the real-time always-active analog voltage envelope of the acoustic waveform.
Type · signal
AN3
Analog range-voltage output, scaling factor (Vcc/1024) per cm; output corresponds to the most recent range data.
Type · analogue outputVoltage · Output scale depends on supply: about 4.9 mV/cm at 5 V, about 3.2 mV/cm at 3.3 V; hardware-limited range about 700 cm at 5 V or 600 cm at 3.3 V.
RX4
Ranging control input. Internally pulled high; left unconnected or high makes the sensor continually measure, held low stops ranging, high for 20 us or more commands a range reading.
