MaxBotix MB7574 SCXL-MaxSonar-WRST7

The weather resistant SCXL-MaxSonar-WRS self?cleaning sensor is a rugged ultrasonic sensor component module. This outdoor sensor provides very short to long distance detection and ranging in a compact, robust PVC housing. The ultrasonic sensor meets the IP67 water intrusion standard and matches standard electrical 3/4?inch PVC pipe fittings.

The MB7574 SCXL-MaxSonar-WRST7 self?cleaning sensor is a cost-effective, rugged ultrasonic sensor that is designed for reliable snow-depth measurement. The MB7574 features a self-cleaning transducer to remove condensation and ice buildup when operating in cold conditions. The MB7374 self?cleaning sensor is the recommended sensor for snow-depth measurement for users requiring TTL serial data. The MB7574 self?cleaning sensor has an internal filter that is a recent biased exponential weighted average. This filter is limited to change a maximum of 1 mm per reading. The sensor accurately applies temperature compensation to every reading, using either the integrated temperature sensor or the optional external temperature sensor (HR-MaxTemp).
