The Milesight WS203-868M combines a passive-infrared motion detector (up to 6 m) with built-in temperature and humidity sensing. Interchangeable Fresnel-lens covers adjust the detection field between a wide 120° × 100° pattern and narrower angles to suit the installation.
It measures –20 °C to +60 °C (±0.2 °C) and 0–100 % RH (±2 %), runs up to 10 years on a 4000 mAh Li-SOCl₂ battery, stores records locally with retransmission, supports Milesight D2D and is configured via NFC. UL94 V0 flame-retardant IP30 enclosure.
Before you install
- Setup: via the Milesight ToolBox app (NFC).
- Power: a lithium battery (ER18505) included, up to ~10-year life.
- Data: over LoRaWAN — needs a LoRaWAN gateway to send data (sold separately); remote monitoring via the Milesight platform is free for up to 10 devices. Also supports Milesight D2D for direct control without a gateway.
