ENVIRONMENTAL NOISE SENSOR (ISL EM1400)

 

The ISL EM1400 Environmental Noise Sensor is an omni-directional acoustic sensor with wide dynamic range and stable performance. With two modes of slow and fast measurements, it can meet the requirements of a number of applications.
With built in thresholds, it can sample the noise level periodically and send alerts when noise levels exceed predetermined limits.


The ISL EM1400 Environmental Noise Sensor will find uses in a range of applications, including construction, industrial environmental noise monitoring, smart city noise monitoring, office and schools workplace monitoring and motor preventative maintenance.

Easy to Install

Choosing wireless sensors and a cloud platform enables you to reduce your installation and maintenance costs.

ADDITIONAL INFORMATION

CONFIGURABLE THRESHOLDS

Configurable high/low thresholds allow different transmit intervals when thresholds are crossed providing advanced edge intelligence to the network, and enable alarms to be generated by Realtime-Online™.
 

REAL-TIME MONITORING 

Data from every sensor in your network is reported back through Invisible Systems Big Data architecture either to our Monitoring and Analytics platform Realtime-Online™, or to a partner cloud platform via our API, ensuring that your data is visible, actionable and valuable to your organisation.
