Tilt Sensor AT407

This AT407 basic tilt switch can easily be used to detect orientation. Inside the can is a ball that make contact with the pins when the case is upright. Tilt the case over and the balls don't touch, thus not making a connection. There are numerous uses for these basic sensors, but keep in mind you might need to use some debouncing code, as the sensor...

Gravity: Digital 10.525GHz Microwave Sensor (Motion Detection)

1 review

The 10.525GHz microwave motion sensor applies the Doppler effect to detect moving objects using microwaves. This differs from the method used by a regular infrared (IR) sensor as microwave is sensitive to a variety of objects that are microwave-reflective, and its sensor readings are not affected by the ambient temperature.
