JC-ZY-ZN03 Wireless Noise Sensor
The noise sensor developed by our company is a noise sensor with a wide sound frequency range, high sound intensity dynamic range, and easy operation. It is suitable for fire pre-alarms in places such as electricity, petrochemicals, homes, and warehouses. The detector has the characteristics of high sensitivity, stability and reliability, low power consumption, beautiful and durable, easy to use and so on.
The sensor is small in size, light in weight and flexible in installation. Its sound frequency measurement range covers all frequencies (20-20KHz) that the human ear can hear. The measured sound intensity energy range meets all the requirements of the national noise management standards.
