Mb7137 i2cxl-trashsonar-wr High performance ultrasonic trash bin measurement Mb7137 i2cxl-trashsonar-wr ultrasonic sensor product description The mb7137 i2cxl-trashsonar-wr is a weather resistant sensor designed for trash bin measurement. The mb7137 i2cxl-trashsonar-wr features the i2c communication interface. This allows for up to 127 sensors to be operated on a single bus for a network of trash bins that are monitored by a single control device for multiâ??sensor operation. High output acoustic power combined with continuously variable gain, real-time background automatic calibration, real-time waveform signature analysis, and noise rejection algorithms results in virtually noise free distance readings. This holds true even in the presence of many of the various acoustic or electric noise sources. The i2cxl-trashsonar-wr sensors are factory calibrated to match narrow sensor beam patterns and provide reliable mid-range detection zones. Mb7139 is the standard version of this sensor.
