Product Description
WS202-868M PIR & Light Sensor is a compact, battery-powered LoRaWAN indoor sensor combining passive infrared (PIR) motion / occupancy detection with bright-or-dark light status.
Designed for smart homes, offices, schools, warehouses and commercial facilities, it can report presence events and support occupancy-based lighting or other automated scenes.
The PIR sensor detects motion at distances of up to 8 m , with 120° horizontal and 100° vertical sensing coverage.
Its built-in ambient-light sensor determines Bright / Dark status against a customizable threshold within 1–60,000 lux .
Applications

Product Features
- Uses passive infrared (PIR) motion detection with a Fresnel lens to detect occupancy changes in indoor rooms.
- Maximum detection range is 8 m and is installation-dependent.
- Wide PIR detection angles: 120° horizontal coverage and 100° vertical coverage.
- Light status sensor classifies the environment as Bright or Dark.
- Bright / Dark classification threshold can be defined over the 1–60,000 lux range.
- Combining light thresholds and detected movement supports context-sensitive lighting-control scenes.
- WS202-868M is specified as an EU868 / 868 MHz radio variant; the exact shipped frequency must be verified.
- Milesight WS202 family includes alternative CN470, IN865, RU864, US915, AU915, KR920 and AS923 variants.
- 868 MHz transmit power is 16 dBm; receiver sensitivity is −137 dBm at 300 bps.
- Supports LoRaWAN OTAA/ABP Class A communication and an internal antenna.
- LoRaWAN range may reach up to 15 km under clear line-of-sight conditions; indoor range is lower and environment-dependent.
- Milesight D2D supports ultra-low-latency communication and direct control with other supported Milesight nodes without a LoRaWAN gateway.
- Compatible with standard LoRaWAN gateways/network servers and Milesight IoT Cloud or Development Platform.
- Device setup and changes are performed locally using a compatible mobile app over NFC; the supplied datasheet does not specify remote configuration by downlink.
- Built-in NFC supports convenient provisioning and card-emulation mode.
- Threshold alarms and Milesight D2D controller features enable building automation.
- Power is provided by one 1,650 mAh ER14335 lithium thionyl chloride (Li-SOCl₂) battery.
- Manufacturer EU868 laboratory battery life: about 4.2 years at SF7 or 2.4 years at SF10 with 30-minute reporting, 30 triggers/day and 25°C.
- Internal status indicator: one LED; one internal reset button.
- Temperature tolerance −20°C to +60°C; relative humidity 0–90% (non-condensing).
- IP30 white anti-flaming polycarbonate housing designed for indoor deployment.
