18mm 40kHz Transceiver Integrated Ultrasonic Sensor Waterproof

Product Description

PRODUCT INTRODUCTION

Ultrasonic Sensor

Excellent environmental adaptability: Working through sound waves instead of light, it can reliably detect highly reflective or transparent objects such as glass and liquids, without being affected by lighting, color, transparency, etc. It can also operate stably in harsh environments such as dust, fog, and darkness.
·Extremely cost-effective: mature technical solutions and low prices. For example, the cost of 3D ultrasonic sensors is only a tiny fraction of that of laser radar solutions, making them very suitable for low-cost applications such as reverse radar and liquid level gauges.
·Stable and accurate distance measurement: At medium to short distances (usually within a few centimeters to 10 meters), the distance measurement accuracy can reach centimeter or even millimeter level (with an error of ± 1mm).
·Simple, reliable, and interference free: It does not require mechanical transmission, is less susceptible to electromagnetic interference, and does not require a radio spectrum license, naturally avoiding signal conflicts with devices such as Wi Fi and Bluetooth.
·Lightweight, fast, and low-power: The structure is simple and lightweight, with almost no moving parts, fast response, and low power consumption requirements, which is in line with the trend of the Internet of Things and portable devices.
