Gravity: Digital Infrared Motion Sensor For Arduino Introduction This is a simple to use arduino motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low. This sensor checks for infrared heat in it's detecting angle. Human body, pets and several other things emit energy that the sensor is looking for, it compares with the snapshot and if t..

Gravity: Digital Tilt Sensor for Arduino / Raspberry Pi Introduction This is an arduino tilt sensor. It is used to detect orientation. Inside the sensor, there is a ball that make contact with the pins when the case is upright. Tilt the sensor over and the balls don’t touch, thus not making a connection.Here is the principle of tilt sensor to illustrate how it works: Simple plug to our Arduino IO Sensor Expansion Shield, you can mak..

Gravity: Digital Microwave Sensor (Motion Detection) Introduction The microwave 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. This type of microwave sensor is widely used in industrial, transportatio..
