Features of the weather-resistant MB7544, SCXL-MaxSonar-WRST4, include the reduced impact of condensation and frost when ran continuously in closed or high-moisture environments, millimeter resolution, short to long distance detection, range information from 500mm to 5000mm for the nearest detectable target, heightened sensitivity over our standard sensors, a 0.6Hz read rate, and various output options: pulse-width, analog voltage, and TTL serial.
The MB7544 from the SCXL-MaxSonar-WRS line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing that meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings.
The SCXL-MaxSonar-WRS sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.
The MB7544 has an internal filter that will reset to targets that are considered valid outside of a 2% distance to the target window. This makes the sensor ideal for targets that occasionally move rapidly. The sensor accurately applies temperature compensation to every reading, using either the integrated temperature sensor or the optional external temperature sensor, HR-MaxTemp.
In addition, the MB7544 offers virtually noise-free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.
