GH-311RT ultrasonic module user manual, introduces the module external connection diagram, DC load circuit diagram, AC load circuit diagram and main technical parameters, product features include high sensitivity, high reliability, high stability, high and low temperature resistance, humidity resistance, shock resistance, vibration resistance and so on
The GH-311RT(T) ultrasonic module is designed for motion detection of people or objects in indoor and outdoor anti‑theft applications, such as home security, vehicle protection, and ATM monitoring. The manual provides wiring diagrams, power connections, and safety warnings for use in high‑voltage or high‑temperature environments.
Key specifications include a supply voltage of DC6‑12 V, low static current (<2 mA), high/low level outputs of 5 V/0 V, detection angle up to 15°, and a detection distance ranging from 2 mm to 3.8 m (with a transmission range of 3‑12 m). The document also outlines proper connection of the power positive and negative terminals and includes safety notices for hazardous locations. This manual is written in Chinese.
