Therefore, the 9V signal is then lowered once more using a voltage divider circuit. When the PIR sensor is triggered, it activates the timer circuit. The timer circuit is driven by a 555 timer.

The sensor does have some limits. It can only detect motion up to about 16.5 feet away. And while Philips will give you the option of reducing that — that is, only turning on lights when motion ...

Feels like a bummer for Kickstarter backers, but for anyone looking for a fun coding project, the $29.99 Motion Sensor Kit is available right now and looks like it will enable a lot of fun projects.

Motion Detection: Detects movement in the dark with a 120° sensor range. Dual Brightness Levels: Low for soft lighting; high for bright illumination. 2800K Warm Light: Soft, eye-friendly lighting.

The Shelly Motion sensor is quite sensitive and offers lots of options—and the promised year of battery life is compelling. But for $40, you’ll find numerous less-expensive alternatives, and ...
