Backplane Systems Technology is proud to introduce ICP DAS PIR-234L-E. The ICP DAS PIR-234L-E sensor module combines a PIR motion sensor with temperature and humidity sensing, ideal for both residential and commercial use. Its high sensitivity covers a 4-meter height and a 14-meter diameter, making it highly effective in various environments.

This module’s standout feature is its adjustable time-delay, allowing customization of sensor activity duration post-motion detection. It houses four PIR motion sensors, enhancing sensitivity and detection range. An internal photosensor smartly adjusts to environmental light, complemented by an LED indicator for the PIR and temperature sensor status. The integrated temperature sensor is key in maintaining comfortable room conditions.

Beyond motion sensing, the PIR-234L-E can function as a temperature or fire alarm. Its relay output controls lighting via the PIR or temperature sensor, supporting multiple lighting setups including incandescent and LED lights. Compatibility with various communication interfaces and protocols like RS-485, Ethernet, and Wi-Fi, along with DCON and Modbus RTU/TCP support, ensures seamless system integration.

Installation and maintenance are streamlined with a screw-free quick-connect connector and simple switch controls. The fireproof casing and minimalist design add to its practicality and aesthetic appeal.

Versatile in application, the PIR-234L-E is suitable for lighting in diverse settings, enhancing safety, comfort, and energy efficiency with its advanced sensor technology.
