Mb7139 xl-trashsonar-wr High performance ultrasonic trash bin measurement Mb7139 xl-trashsonar-wr ultrasonic sensor product description The mb7139 xl-trashsonar-wr1 is a weather resistant sensor designed for trash bin level measurement. The mb7139 xl-trashsonar-wr1 reports the range to the first detectable target in a trash bin. This sensor is our most recommended sensor for testing within trash bins. 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 xl-trashsonar-wr sensors are factory calibrated to match narrow sensor beam patterns and provide reliable mid-range detection zones. Mb7137 is the i2c version of this sensor.
