The RY-CZS/485 tube noise sensor (outdoor) is developed and produced by Handan Yunnong Intelligent Agricultural Technology CO., LTD. The original intention of the design is for the current environmental monitoring in the noise test and the online monitoring sensor is currently at a relatively high price. Built-in high-sensitivity sensor and data acquisition module, integrating measurement and transmission. The sensor can also be connected with the dust detector to become a part of the dust detector to measure the noise-related data of the measured environment. The noise monitor with industry standard output (RS485) realizes real-time monitoring of on-site noise. Its outstanding features are high precision, strong versatility, and high cost performance.
