Description

The CESVA TA120 is a Class 1 noise measuring sensor for continuous environmental noise monitoring, built to IEC 61672-1. It measures LAeq over a 35-120 dBA range, 24 hours a day, and sends the results to your monitoring platform over Ethernet, Wi-Fi or a 2G/GPRS modem.

It is designed for municipalities, smart city operators and environmental consultants who run noise surveillance networks around roads, nightlife areas, construction sites and industrial boundaries. The TA120 mounts on street lights, facades and billboards and needs little routine maintenance.

Core Capabilities

Class 1 Measurement LAeq to IEC 61672-1 Class 1, with a selectable second parameter (LCeq, LAFmax or LASmax) and integration times from 1 s to 60 min.
Flexible Connectivity Ethernet (RJ45) as standard, with Wi-Fi, a 2G/GPRS modem or a 4-20 mA current loop module as options. Data is sent over HTTP or HTTPS.
Many Power Options Runs from mains, PoE, 12 VDC or the street lighting network, with an optional internal battery and solar panel kit for sites without permanent power.
Outdoor Ready With the TK120 outdoor kit and windscreen, the sensor reaches IP65 to IEC 60529 and operates from -10 to +50 °C.

Applications

Smart City Noise Maps: Permanent monitoring points for strategic noise maps and action plans.
Leisure & Nightlife Areas: Track night-time noise levels around bars, venues and events.
Construction & Industry: Monitor site boundaries against permitted noise limits.
Low-Frequency Noise: Use the C-weighted LCeq option to assess low-frequency content from traffic and machinery.

Technical Integration

The TA120 sends measurements directly to a monitoring platform:

Platforms: CESVA NoisePlatform, Sentilo, FIWARE, Telefonica, SmartyPlanet and other platforms that accept HTTP/HTTPS.
Data format: UL2.0 or JSON payloads over HTTP or HTTPS.
Backhaul: Ethernet (RJ45) standard; Wi-Fi, 2G/GPRS modem or CL120 4-20 mA module optional.
Configuration: CESVA Sensor Manager software for Windows.
Accessories: BA120 internal battery, PS120 solar kit (needs BA120), TK120 outdoor kit and PV120 windscreen.
Setup help: Talk to the shopioT technical team about platform integration, power and mounting for your site.

Frequently Asked Questions

What does Class 1 mean?

Class 1 is the higher precision class defined in IEC 61672-1 for sound level meters. The TA120 measures to Class 1 so its readings can be used for formal environmental noise monitoring.

What is the measurement range?

35 to 120 dBA in a single range, measured continuously 24/7.

Can it run without mains power?

Yes. It can run from 12 VDC, PoE or the street lighting network. With the BA120 internal battery and the PS120 solar panel kit it can operate at sites with no permanent supply.

Which platforms does it work with?

CESVA NoisePlatform, Sentilo, FIWARE, Telefonica and SmartyPlanet, plus any platform that can receive UL2.0 or JSON data over HTTP/HTTPS.

Is it suitable for outdoor installation?

Yes, with the TK120 outdoor kit and PV120 windscreen it reaches IP65 and operates from -10 to +50 °C.
