MB7137, MB7138, MB7139 

XL-TrashSonar-WR Series Ultrasonic Trash Sensor Product Description
The XL-TrashSonar-WR sensor series provide users with robust range information in air. These sensors also feature high-power acoustic output along with real-time auto calibration for changing conditions (supply voltage sag, acoustic noise, or electrical noise), operation with supply voltage from 3.0V to 5.5V, object detection from 0-cm to 350-cm, and sonar range information from 20-cm out to 350-cm with 1-cm resolution. Objects from 0-cm to 20-cm typically range as 20-cm. ( 25cm for the MB7138) The sensor is housed in a robust PVC housing, designed to meet the IP67 water intrusion standard. This sensor line is available in the following package types — 3/4" PVC threading, 1" NPS pipe threading, 1" BSPP pipe threading, and 30mm 1.5 pipe threading.

The user interface formats included are pulse-width, analog voltage output, RS232 serial output, and I2C (MB7137).
