The Philips Hue motion sensor can be connected to your existing Hue system, and will trigger your lights when it detects movement.
What's more, the sensor knows when it's day or night, which Philips says allows it to provide "the perfect shade of light at the right time".
Hue lightbulbs can already by controlled via voice command, as well as through your smart device and wearables, but the company is attempting to make things easier with its latest addition to the range.

Sridhar Kumaraswamy, Business Leader Home Systems at Philips Lighting said: “As the leader in connected lighting, we constantly seek to evolve our system and make it simple and easy to use.
"The introduction of Philips Hue motion sensor not only provides hands free control but also enables lighting to respond to your needs more smartly.
"For example, by guiding you through your home at night, and no longer having to remind the kids to turn off the lights when leaving a room, keeping you even more energy efficient."
Philips also introduced a new generation of Hue colour ambiance bulbs, which, it says, will provide richer greens and blues.
