DYP-A17NYUW-V1.0 UART Auto Ultrasonic Well Level Sensor (25-1000cm Range)

The module uses a UART (TTL) serial interface for communication. It outputs distance data in a predefined packet format, which can be directly read by microcontrollers like Arduino, ESP32, or industrial PLCs with a UART port. The baud rate and data format are typically fixed by the manufacturer's firmware.

Yes, it is suitable for measuring the level of most common liquids like water, oils, and non-foaming chemicals. The IP67-rated, waterproof probe is designed for direct exposure. However, for highly turbulent surfaces or liquids that produce heavy foam, the accuracy may be affected due to the nature of ultrasonic reflection.

It operates from a 3.3V to 5.0V DC power supply, consuming less than 15mA during operation. Connect VCC to your power source (3.3V/5V), GND to ground, and the TX/RX pins to the corresponding UART pins on your controller. Ensure correct logic level matching if your system uses 3.3V logic.

The blind zone (or dead zone) is the minimum distance from the sensor face within which it cannot reliably detect objects. For this sensor, objects closer than 25cm may not be measured accurately. Ensure the liquid surface is always beyond 25cm from the transducer for valid readings.

Yes, its IP67 waterproof rating and anti-condensation probe design make it suitable for outdoor and harsh environments. For permanent installation, ensure the mounting protects the cable gland from direct, sustained water jets and consider the operating temperature range for your climate.
