The PIR Motion Detector Modules

The ICP DAS PIR-234/PIR-234L series are equipped with four PIR Motion Sensors to increase sensitivity and the ability to detect infrared waves generated by the human body within a coverage area of 360° coverage area with a diameter of approximately 9 meters(PIR-234) or 14 meters(PIR-234L).

These modules are designed for indoor motion detection and can be configured to automatically turn on lights when motion is detected, and also contain a temperature and humidity sensor for measuring indoor temperature and humidity. Alternatively, these modules can be configured to activate a fire alarm.

With the built-in RS-485 and Ethernet interfaces which support DCON and Modbus RTU/ TCP protocols, these modules can be easily integrated into existing HMI/SCADA/central control systems.

A free Utility is provided that allows configuration information and data to be displayed in a powerful chart format and can be exported to Microsoft Excel. These modules feature screw-free & quick-connect connector as well as DIP and rotary switches, making the modules easy to install, repair, and maintain.

The casing of each module is made from UL94-V2 rated fireproof material, and the white minimalist exterior design ensures they blend well with interior decoration.
