XKC-007Y-JQ-X transceiver one waterproof module, is the use of transceiver one closed waterproof belt probe, with a certain degree of dust and waterproof, suitable for wet, bad measurement occasions. This module uses 12V relay output, is a simple operation of high-performance, high reliability, commercial-grade functional modules. First, the product introduction Ultrasonic module is the air as a medium to spread, non-contact target detection and ranging, in a region to detect the object of the sensor. This sensor is not affected by the color or other visual characteristics of the object being detected. The ultrasonic sensor emits a high frequency of sound waves to detect in the environment while receiving ultrasonic echoes that reflect reflection from nearby objects. The sensor outputs the corresponding data signal by processing the echo time. Second, distance measurement Requires 100% to measure reliable and stable distance values, the measured object to ensure that the sensor within the effective range. Most users find that the sensor can also be measured outside the dead zone or range, and the company does not guarantee the accuracy of the measured distance value for different measurement objects due to the physical characteristics of the ultrasound.
