Colorlight SSR-NOISE Noise Sensor
The Colorlight SSR-NOISE is a decibel-level sensor for monitoring sound in an LED display installation. Its V1.0 specification lists a 30–120 dB measuring range, a maximum error of 0.5 dB and a response time below 3 seconds. The standard cable length is 5 m.
Sensor integration
The sensor uses multipoint calibration and a separately packaged stainless-steel probe that can be integrated into other equipment. Shielding around the main circuit components helps reduce interference. The listed output types are TTL, IIC/I2C and RS485, with standard Modbus RTU specified for the RS485 interface. Match the output and connector to the receiving equipment before installation.
