CESVA was lucky to succeed facing the challenge: Providing our Sound Level Meter technology of IoT connectivity. In 2017 the TA120 Noise Sensor was launched into the smart cities market. Nowadays there are more than 150 TA120 noise sensors installed in the city of Barcelona connected to its Sentilo platform.

TA120 is a unique product; it is the only one noise sensor coming from the world of sound level meters and environmental acoustics. TA120 offers class 1 accuracy of measurement according IEC 61672 standard, wide dynamic range of measurement from 35 to 120 dBA over a temperature range from -10 to +50 °C and can be certified unit by unit.

CESVA, founded in 1969 in Barcelona, has been working to provide solutions to manage noise problems helping to protect the environment and improving people's quality of life.
