Sensor PIR e de luz sem fios Milesight WS202-868M LoRaWAN detetor de movimento e luz ambiente 868 MHz

The Milesight WS202-868M is a wireless PIR motion and ambient light detector that communicates over LoRaWAN in the 868 MHz band. Designed for battery-powered remote sensing, it detects human presence using a passive infrared sensor and measures ambient light levels to support automation, security monitoring and energy-saving workflows. The device reports events and light measurements to LoRaWAN gateways for centralized management and integration with building automation or IoT platforms.

Advantages

The sensor combines PIR motion detection and ambient light measurement in one compact, low-power device, enabling presence-based control and lighting adjustments without wiring. Its LoRaWAN connectivity offers long-range, low-bandwidth reporting suitable for large buildings and dispersed sites. Battery operation simplifies installation and reduces infrastructure costs while providing configurable reporting intervals and thresholds for tailored monitoring and alerting.

Suitable for

• Building automation for lighting control and HVAC optimization
• Security and intruder detection in offices, corridors and storage areas
• Energy-saving deployments where presence and light level data reduce consumption
• Remote monitoring in warehouses, retail spaces and public buildings

Key specifications

• Wireless protocol: LoRaWAN (868 MHz)
• Sensing: PIR motion detection and ambient light measurement
• Power: battery-powered for wireless installation
• Installation: wall- or ceiling-mounted sensor housing
• Data reporting: event-driven and periodic reporting to LoRaWAN network
• Operating environment: indoor use for automation and monitoring

How to use

Install the sensor at a location with clear line-of-sight to the area to be monitored, typically on a wall or ceiling at an appropriate height for PIR detection. Activate and join the device to a LoRaWAN network through the network server or gateway provisioning process. Configure reporting intervals, motion sensitivity and light thresholds via the device configuration profile on the LoRaWAN management platform. Once commissioned, the sensor will transmit motion events and ambient light readings according to configured rules.

Recommendations

For reliable motion detection, avoid mounting near large heat sources or air vents and ensure the sensor has an unobstructed view of the monitored area. Use adjustable reporting intervals and thresholds to balance responsiveness and battery life, and verify LoRaWAN signal strength at the mounting location before final installation.
