DYP-H01 Capacitive High-Precision Ultrasonic Distance Sensor – 10cm to 800cm Range

The DYP-H01 is a Commercial-Grade Ultrasonic Ranging Module built for accurate, non-contact distance and height measurement. It uses a capacitive electrostatic transducer probe to deliver millimeter-level resolution across a measuring range of 10 cm to 800 cm, with a dead-band of 10 cm for objects placed closer than the minimum range. The module supports multiple output interfaces, including UART, PWM auto-output, PWM controlled-output, and RS485, allowing easy integration into a wide range of control systems and embedded projects. Its 40kHz ultrasonic sensor and on-board temperature-compensation circuit correct for ambient temperature deviation, ensuring stable and repeatable readings between -10 to +50 deg C.
Built with a stainless-steel shell, the DYP-H01 is well-suited to harsh and outdoor operating environments, offering high anti-interference performance and consistent data output even under fluctuating conditions. It can accurately detect flat objects up to 800 cm away and human bodies within a range of 100 mm to 3000 mm, making it suitable for robot obstacle-avoidance, automatic control systems, and intelligent altimeter applications. The compact, light-weight design combined with fast response time and high measurement accuracy makes this module a dependable choice for both slow-moving target detection and fixed-distance monitoring tasks.
