Remarks:
(1)Testing result under temperature 25±5℃, humidity 65%RH, input voltage 5.0V, 900ms working cycle.
(2)Temperature 25±5℃, humidity 65%RH, 50cm*60cm flat carton measured data, default to the bottom of the reflective structure surface as the detection starting point. In order to improve the stability of the ranging, keep last measured value if distance change is less than 2cm.
(3)Temperature 25±5℃, humidity 65%RH, For the reference data obtained from the test of aφ75mm*100cm white PVC pipe with a distance of 100cm, the measurement distance is also different at different angles. The above test data are all carried out in an open room, and the installation height of the detection module is 30cm from the ground.
Product Features
The DYP-A17 ultrasonic sensor integrates multiple advanced features for versatile applications. Equipped with an intelligent signal processing circuit, it offers a small blind zone and a long detection distance, covering a measuring range of 25-1000 cm. Its built-in high-precision distance sensing algorithm ensures remarkable accuracy with an error margin of less than 1 cm. The sensor features a controllable beam angle, delivering high sensitivity and strong anti-interference capability, while the embedded target recognition algorithm enhances target identification accuracy.
For connectivity flexibility, it supports optional output interfaces including PWM, UART auto, UART Controlled, and RS485 controlled. An internal temperature compensation function maintains stable output across -15℃ to +60℃. Its anti-water process design mitigates probe condensation issues, while the low-power consumption architecture ensures a static current below 10μA and operating current under 15mA, powered by a 3.3-5.0VDC low voltage input. Compliant with the IEC61000-4-2 standard, the anti-static electricity design adds durability, and firmware remote updating enables easy system upgrades.

Product Installation Instructions
1.Product advantage
The design of algorithm of sensor module is based on the sewer structure. The module can effectively filter the interference of conventional facilities in the well (stairs, protruding bricks and stone walls, inlet and outlet pipes, small hanging objects on the well wall, etc.). Accurately obtain the current water level to prevent the accumulation of water from overflowing.
2.Installation requirements
Well water level application shown in the figure below. The best position of the module should be far away from the protruding object (stairs) of the well wall, and the flattest side of the well wall is selected as the installation support. The fixed module should be vertical to the water surface, Parallel to the well wall. The best installation distance between the module and the well wall on the same side is 25cm-30cm.
Notice
(1)Please pay attention to the structural tolerances when designing. Unreasonable structural design may cause temporary abnormalities in module functions.
(2)Please pay attention to the evaluation of electromagnetic compatibility when designing. Unreasonable system design may cause malfunction of the module.
(3)When the boundary application of the product limit parameter is involved, you can contact after sale service to confirm the relevant precautions.
