DS1603L Ultrasonic Distance Sensor

DS1603L V1.0 Ultrasonic Sensor (datasheet) over UART without modification.

This sensor can measure ranges between 5 centimeters and 200 centimeters with a resolution of 1 millimeter.

Since this sensor reads every few seconds, Sensor Filters are highly recommended.

To use the sensor, first set up an UART Bus with a baud rate of 9600 and connect the sensor to the specified pin.

NOTE

These sensors read from the bottom of a tank and need to have some kind of couplant for them to work. There can be no air gap between sensor and bottom of container. Silicone grease is recommended and easily found at most automotive or hardware stores.
