What It Does

Built for occupancy.

A PIR presence and light sensor in one compact unit. Detects motion up to 8 m with a 120° × 100° field of view and measures ambient light from 1 to 60,000 lux — the combination needed for occupancy-triggered lighting control. Battery-powered with NFC configuration and Milesight D2D for direct device-to-device operation without a gateway. LoRaWAN decoder: Milesight WS202 payload decoder & codec (GitHub)

Highlights
Motion and light together
A single unit reports both presence and ambient light level — giving facilities teams the two readings needed to understand whether a space is occupied and how it is being lit, without deploying separate sensors.
D2D without a gateway
Milesight D2D lets the WS202 trigger a light switch or relay directly, peer-to-peer, so occupancy-controlled lighting can work even if the LoRaWAN gateway is offline.
Four-year battery life
Running from a single ER14335 lithium cell, the sensor lasts roughly four years at normal reporting intervals — meaning no routine battery visits across a school or housing block.

Complete The Setup

You will also need a gateway.

Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites.

On The Platform

A device on its own, or part of the bigger picture.

Buy this device and run it yourself, or have it monitored on the Planetic platform — live dashboards, standards tracking and automatic alerts, with the compliance evidence kept for you.

Questions

Good to know.

Do I need anything else to use this device?
Every LoRaWAN sensor needs a gateway to reach the internet. One gateway covers a whole building — the Milesight UG65 is the standard choice for most sites. The gateway itself does not need a sensor to run.
Is the price ex VAT?
Yes — all prices shown are ex VAT. VAT is added at checkout where applicable.
Can I have it monitored on the Planetic platform?
Yes. Buy the device outright and run it yourself, or have it monitored on Planetic — live dashboards, standards tracking and automatic alerts, with compliance evidence kept for you.
