High Performance Ultrasonic Precision Rangefinder
Module : DYP-A08
A08 series module is a module that uses ultrasonic sensing technology for distance measurement. The module adopts high-performance processor and high-quality components, the product is stable and reliable, and has a long service life. The module uses a waterproof ultrasonic transducer, which is highly adaptable to the working environment. The module has built-in high-precision ranging algorithm and power management program, with high ranging accuracy and low power consumption.
According to different characteristics and advantages, the modules are divided into three series:
A08A series modules are mainly used for plane ranging;
It has four output modes, namely: PWM processing value output, UART automatic output, UART controlled output and switch output.
The measurement setting range of this module is 25~1100cm, and the stable measurement reference range is 25cm~800cm.
Under the UART automatic output, the RX lead is connected to the low level, and the output data is the real-time value (real-time measurement data), which can improve the output data refresh speed; when it is suspended or connected to the high level, the output data is the processed value (data processed by the algorithm) , The output data is more stable, but the refresh speed has decreased.
A08B series modules are mainly used for human body distance measurement;
It has four output modes: PWM processing value output, UART automatic output, UART controlled output and switch output.
The measurement setting range of the module is 25cm~600cm, and the stable measurement reference range is 25cm~500cm.
Under the UART automatic output, the RX lead is connected to the low level, and the output data is the real-time value (real-time measurement data), which can improve the output data refresh speed; when it is suspended or connected to the high level, the output data is the processed value (data processed by the algorithm) , The output data is more stable, but the refresh speed has decreased.
A08C series modules, mainly used for trash can distance measurement;
It has only one output mode for UART automatic output.
The measurement setting range of the module is 25cm~200cm, in order to effectively filter out the diameter of the trash can and the reflection echo of the baffle to detect the garbage in the trash can normally, the module has a built-in frame filtering algorithm, and receives a falling edge pulse through the RX lead. It can automatically filter the interference of the inner frame at a distance of 30cm~80cm, and can filter up to four frame interference at the same time.

Remarks:
(1) Typical data obtained by testing at a temperature of 25°C, a humidity of 65% RH, a power supply of 5.0V, and a 100ms duty cycle. The PWM processing value output duty cycle is 200ms. The working cycle of A08C series modules is 500ms.
(2) Temperature 25°C, 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 should be subtracted. The range is 25cm~150cm in the switch output mode.
(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.
（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-A08 ultrasonic sensor incorporates advanced technologies to deliver robust distance measurement capabilities. Equipped with an intelligent signal processing circuit, it features a small blind zone and extended measuring range. The built-in high-precision ranging algorithm ensures a minimum error of less than 10mm, while the controllable measuring angle enhances sensitivity and anti-interference performance. A target recognition algorithm further boosts object identification accuracy.
Its ultrasonic transducer intelligent matching technology automatically adjusts the transducer to the optimal working state, ensuring consistent module performance. The sensor supports professional measurement modes for human body, flat objects, and garbage in bins. With versatile output options—including PWM processed value, UART output, or switching values—it offers high interface adaptability.
The onboard temperature compensation function corrects temperature deviations, enabling stable ranging from -15°C to +60°C. Designed for low power consumption, it draws <5μA in standby and <15mA during measurement, operating on a 3.3~5.0V low-voltage supply. Electrostatic protection on output leads complies with IEC61000-4-2 standards, ensuring reliability across its -15°C to +60°C working temperature range.
