Explosion-proof environment sensor

Explosion-proof environment sensor designed to measure various environmental conditions. The sensor combines VOC, humidity, light, barometric pressure and sound/noise sensors, as well as a 3-axis accelerometer.

Ex environment sensor uses a unique and innovative algorithm that enables highly accurate determination of earthquakes

Ex environment sensor enables continuous monitoring of room air quality using a VOC sensor

Ex environment sensor has Interface:

• Bluetooth® low energy (Bluetooth® v5.0)*5,

• USB communication (USB2.0)

Note: To use the Ex environment sensor in a hazardous area, the device must be protected to at least IP 65, so it must be placed inside the enclosure.

The Ex environment sensor is connected through an industrial USB 2.0 connector to an intrinsically safe barrier Ex USB 2.0.

The Ex environment sensor have a “hot-plug” function which allows them to be connected and disconnected without stopping, shutting down or rebooting the system.
