PIR Motion Detector

PIR-130-AC (ordering code PIR-130-AC CR) combines a 360° passive infrared motion sensor with a temperature sensor in one ceiling-mounted module. It is aimed at indoor lighting and ventilation control, where it can switch a connected load when motion is detected, and at room temperature monitoring or fire alarm signalling.The motion section has a photo sensor, so switching can take ambient light into account. Time delay, lux level and sensitivity can be adjusted, using hardware switches or software settings. A relay output, rated at 10 A NO and 6 A NC at 250 VAC, can switch lights directly, with loads of up to 1500 W incandescent or 300 W fluorescent (T8).Status is reported over a single RS-485 port that supports DCON and Modbus RTU at baud rates from 1200 to 115200. Two LEDs show power and communication status and alarm state, which helps with commissioning and fault finding.ApplicationsLights and exhaust fans in common toiletsCommon staircasesParking lightsGarden lightsChanging rooms in shopsCorridorsRoom temperature measurementFire alarm signalling

The PIR-130-DC is a ceiling-mounted indoor sensor module that combines a 360° passive infrared motion detector with a temperature sensor, both reporting over RS-485. It suits engineers who need occupancy-based lighting control or room temperature monitoring on a serial bus, with the relay able to switch a light directly from the PIR or temperature sensor.Detection range, time delay, lux threshold and sensitivity are adjustable, and an internal photo sensor allows smart switch-on control so lights only come on when ambient light is low. The temperature channel can measure room temperature or be set to act as a fire alarm, with a programmable trip point of 65°C.The relay is a Form C power relay rated NO 10 A and NC 6 A at 250 VAC, and the module supports DCON and Modbus RTU over RS-485 at baud rates from 1200 to 115200. Its 10 ~ 30 VDC supply includes reverse polarity protection, and it is rated IP20 for dry indoor installation.ApplicationsCommon toilets, switching lights and exhaust fansCommon staircasesParking lightsGarden lightsChanging rooms in shopsCorridors

The PIR-230-E combines passive infrared motion detection with temperature and humidity measurement in one ceiling or surface-mounted module. Its 360° field of view covers up to 8 m in diameter from a 4 m mounting height, and the built-in relay can switch lighting automatically when movement is detected.Beyond lighting control, the module measures room temperature from -40 ~ +120°C and relative humidity from 0 ~ 100% RH. It can also be set up as a fire alarm, with a programmable trigger of 65°C. An internal photosensor and adjustable time-delay settings let the lighting respond to ambient conditions and occupancy patterns.Communication runs over one RS-485 port and one Ethernet/PoE port, with DCON, Modbus RTU, Modbus TCP and MQTT available. The module accepts 18 ~ 48 VDC or Power over Ethernet, and the screw-free quick-connect terminals and DIP and rotary switches simplify installation and maintenance.ApplicationsLighting and exhaust fans in public toiletsCommon lighting in staircasesLighting in parking areasGarden lightsLighting for changing rooms in shopsCorridor lighting

The PIR-230-WF combines a 360° passive infrared motion detector with a temperature and humidity sensor in one ceiling or surface-mount module. Its relay output can switch a connected light when motion is detected, which suits automated lighting in shared spaces.Communication is available over RS-485, Ethernet with PoE and Wi-Fi, with DCON, Modbus RTU, Modbus TCP and MQTT supported for integration with HMI, SCADA or central control systems. The module can also serve as a fire alarm using a programmable 65°C threshold.Installation is simplified by a screw-free quick-connect connector and DIP and rotary switches. The housing is UL94-V2 rated, and the white finish suits interior décor. The manufacturer lists this variant for Asia only.ApplicationsLighting and exhaust fans in public toiletsCommon lighting in staircasesLighting in parking areasGarden lightsLighting for changing rooms in shopsCorridor lighting

PIR-231-E CR is an indoor sensor module that detects human motion over a 360° field of view, up to 8 m in diameter, and can switch a connected light through its relay output. It also measures room temperature and humidity, so one device can handle occupancy-based lighting and environmental monitoring in the same location.The module offers RS-485 and Ethernet/PoE connectivity and supports DCON, Modbus RTU, Modbus TCP and MQTT, which makes it straightforward to feed data into HMI, SCADA or central control systems. Motion delay can be set by hardware switch or in software, and two wet-contact digital inputs add further monitoring options.Installation is simple, with ceiling or surface mounting and a 0 ~ +35°C operating range. Typical use is in common areas such as public toilets, staircases, car parks and corridors.ApplicationsLighting and exhaust fans in public toiletsCommon lighting in staircasesLighting in parking areasGarden lightsLighting for changing rooms in shopsCorridor lighting

PIR-234-E CR is a ceiling or surface-mount sensor module that detects human presence with four PIR sensors across a 360º field of view. It can switch lighting automatically when motion is detected, and it also reports room temperature and humidity, so one device covers occupancy, climate and lighting control.The module can be set up as a temperature or fire alarm device, using a programmable 65°C threshold. Its two Form A relays rated 16 A at 250 VAC or 30 VDC drive incandescent or LED lighting loads, and an internal photosensor supports smart switch control. Delay times can be set by hardware switch or in software.Connectivity is provided by Ethernet/PoE and RS-485, with DCON, Modbus RTU, Modbus TCP and MQTT supported. The screw-free quick-connect connector and DIP and rotary switches simplify installation and maintenance.ApplicationsStaircase lightingGarden lightsChanging room lighting in shopsLighting for conference rooms, classrooms and pantry roomsCorridor lighting

The PIR-234L-E CR combines four PIR motion sensors with temperature and humidity measurement in one ceiling or surface-mounted module. Its 360° detection field of view, up to 14 m in diameter and 4 m detection height, suits indoor areas where automatic lighting control or occupancy monitoring is needed.A 2-channel power relay can switch lighting directly through the PIR or temperature sensor, and an internal photosensor supports smart switch control. The module can also be set up as a temperature or fire alarm, with a programmable fire alarm threshold of 65°C.Communication is via Ethernet/PoE and RS-485, with DCON, Modbus RTU, Modbus TCP and MQTT protocols, so the module can be integrated into HMI, SCADA and central control systems. The -E variant in this ordering code uses the Ethernet interface.ApplicationsCommon lighting in staircasesGarden lightsLighting for changing rooms in shopsLighting for conference rooms, classrooms and pantry roomsCorridor lighting
