RS485 Modbus Noise Sensor

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   IOT-S300NOIS Datasheet IOT-S300NOIS USER MANUAL
