Product Applications

1Smart cities

According to the ISO survey,Working in an environment with noise levels of 85 decibels and 90 decibels for 30 years.The likelihood of deafness is 8% and 18%, respectively.In an environment with a noise level of 70 decibels, conversation is difficult.

2Smart industry

ISO proposes that workers work 8 hours a day in a noisy environment, but in no case exceed 115 decibels.

3Motor preventive maintenance

Industrial motors specify different limits for noise generation based on factors such as rated power and operating load. In the 70 to 110 decibel interval.

POLYSENSE's WxS880-004 noise sensor, sampling low power battery solution. IP67 meets the needs of mobile arming applications for outdoor inspection.
