Integrated waterproof ultrasonic liquid level sensor DS1603 V1.0

Short Description:

The DS1603 V1.0 ultrasonic liquid level measurement sensor series breakthrough the traditional opening can installation method and achieved the real-time non-contact liquid level monitoring in a closed container. The sensor need be attached to the bottom center of the container to detect its liquid level height. or attached to the side wall of the container to detect whether there is liquid in the container at the monitoring point.
