The iSN-201 series modules can be used for measuring indoor illumination, temperature and humidity. A wide range of interface connections can be selected to suit individual needs, including RS-485/Ethernet/Wi-Fi models. The various models provide support for the DCON and Modbus RTU/TCP protocols, and can be easily integrated into existing HMI/SCADA/ central control systems.

The screw-free quick-connect connector and the DIP and rotary switches make the modules easy to install, repair, and maintain. The white minimalist exterior design ensures that it easy to match with interior decoration.


The WISE-5231 and electric curtain combination with the illumination meter iSN-201-E can easily be setup through a simple web interface and logic control. The two-way interlocking mode integrates the electric curtains and the Building Management System (BMS), and collects environmental sensing data simultaneously. When detecting the indoor temperature or humidity rises or the intensity of sunshine is strong, it will automatically activate the pulling motion of the electric curtain, or enable a personalized scenario to control all curtains or specifi c curtain combinations in the home environment. In addition, the user can edit the scenario and set up the curtain automation at scheduled times.
