This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...

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 ...

A motion sensor ensures that the lights are only on when there are people around to actually see the lights. The circuit also has an adjustable timer so [brmarcum] can change the length of time ...

This is applicable only when a light sensor is soldered in its pads (CDS) on the front of the circuit board. A 47–100K resistor works fine with standard 5-mm LDRs. A word of caution: I could not find ...

The first thing to add was a power management circuit, ... As for sensors, it has a light sensor and an optional 9-axis motion sensor, allowing for gesture sensing, proximity detection, ...

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.
