Colorlight SSR-NOISE noise sensor overview
The Colorlight SSR-NOISE measures ambient sound level for LED display monitoring and control installations. Its direct-reading decibel module covers 30–120 dB, while multi-point calibration and a separately packaged stainless steel probe support integration into an equipment enclosure. The board’s core circuitry is shielded to help resist interference.
Key features
- 30–120 dB measuring range with a response time under 3 seconds.
- 20 Hz–12.5 kHz frequency range and specified maximum error of 0.5 dB.
- Standard 5 m cable and separately packaged stainless steel probe.
- TTL, I²C and RS485/Modbus RTU output options are listed in the Colorlight specification. Confirm the interface supplied with your unit before connecting it.

Connection and installation notes
Match the sensor’s supply voltage, 4-pin connector and output type to the input supported by your Colorlight controller or integration equipment. The specification lists several output types; it does not establish that every output is available simultaneously on every supplied version. IP20 is intended for protected installations, so use a suitable enclosure where the sensor may be exposed to dust or water. Contact us to confirm the exact interface for your project.
