The ET400 smart environment detection panel is widely used to detect PM2.5, formaldehyde, carbon dioxide, ambient temperature and
humidity, usually fixed in the standard box. Customers can flexibly choose the right sensor according to the monitoring needs. What’s
more, it can directly control the ventilation fans. It has been calibrated in Multi IR’s humidity and temperature controlled facility.
The ET400 detection panel supports multiple communication modes, such as RS485, WiFi, ZigBee, LoRa, NB-IoT, by which the detector
is connected to the cloud platform easily. It can be used as the sensors of the smart home system. When the measurements exceed
the threshold which is set by the user, the smart home system will automatically drive the corresponding linkage facility, meanwhile
sending alarm message to the users.
