Technical manual for Dauxi KS101B, KS103 and KS103S ultrasonic distance sensors covering wiring, commands, and configuration.
The Dauxi KS101B/KS103/KS103S series are ultrasonic distance sensors with real‑time temperature compensation and up to 500 Hz detection frequency. They support I2C or TTL‑serial interfaces, offer configurable I2C addresses, and include built‑in noise‑reduction modes for reliable operation in noisy environments.
The manual provides detailed functional summaries, electrical parameters, pin connections, I2C address programming procedures, multi‑range detection commands, temperature and light‑intensity measurement methods, as well as example code for STM32 and other microcontrollers. This manual is written in Chinese.
