RS485 Modbus Noise Sensor with Range 30~120dB

IOT-S300NOIS

The IOT-S300NOIS noise sensor is designed for harmfulness of noise to the human body. Noise can changes in the auditory system and also affect non-auditory system. Long-term exposure to relatively strong noise can cause pathological changes. It interfaces with language communication, affects work efficiency, and even cause accidents.

Outstanding Features:

• Wall-mounted shell, easy to install
• High measurement accuracy, fast response speed
• Range up to 30~120dB
• Communication mode: Modbus RTU communication protocol, RS485 digital output

Applications:

Meteorological station, hydrological station
Flood control, water supply dispatching, power station reservoir water regime management
Agriculture, forestry and other related depratments used to measure precipitation
