The XL-MaxSonar-WRmodel 7070 is one of the most popular ultrasonic sensors that exist, it is waterproof and is designed to be used outdoors. Meets IP67 (protection against water).
This is a robust ultrasonic sensor module with its cover built in PVC. Outdoors it provides measurements of distances as small thanks to high output performance with high acoustic energy.
The acoustic power combined with continuously variable gain, real-time auto calibration, real-time analysis of waveforms, and noise filtering algorithms for real-time measurement results in virtually noise free distance to most users
The XL-MaxSonar-WRA sensors are calibrated in their manufacture, to match the measurement standards and thus provide reliable detection zones in its long-range measurement.
It has a maximum range of 7.5mts, but in person detector uses a maximum of 2.5mts is established.
Your measurement data is sent from the sensor analog output, digital output or serial TTL.
