Remarks:
(1) Typical data obtained by testing with a temperature of 25°C, a humidity of 65% RH, a power supply of 5.0V, and a 900ms duty cycle.
(2) Temperature 25℃, humidity 65% RH, 50cm*60cm flat carton measured data, the detection starting point defaults to the probe surface, if the detection starting point is calculated based on the bell mouth plane, 3.5cm needs to be subtracted, in order to improve the stability of distance measurement. The change of the ranging distance is less than 2cm, and the last measured value is maintained.
(3) The temperature is 25°C, the humidity is 65% RH, and the measured object is the reference data obtained from the test of a φ75mm*100cm white PVC pipe with a distance of 100cm. The measurement distance is different at different angles.
(Tips : 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-A07 ultrasonic sensor integrates multiple advanced features for versatile distance measurement. Leveraging an intelligent signal processing circuit, it achieves a small blind zone and extended measurement range. Its built-in high-precision ranging algorithm ensures a minimum error of <1cm, while the controllable measuring angle enhances sensitivity and anti-interference capability. A target recognition algorithm further boosts accuracy in identifying objects.
With flexible output modes—including PWM processing value output, UART automatic output, and UART controlled output—it offers high interface adaptability. The onboard temperature compensation function automatically corrects deviations, enabling stable ranging from -15°C to +60°C. Designed for low power consumption, it draws <10μA in standby and <15mA during measurement, operating on a low-voltage supply of 3.3~5.0V.
Electrostatic protection on output leads complies with IEC61000-4-2 standards, while the anti-corrosion treated ultrasonic transducer ensures high protection levels. Supporting remote software upgrades, it allows flexible algorithm adjustments, maintaining reliable performance across its -15°C to +60°C working temperature range.
The internal program of the well position detection module is based on the algorithm design of the sewer structure. The module can effectively filter the interference of conventional facilities in the well. Accurately obtain the current water level to prevent overflow of accumulated water.
