Causes and Symptoms of Upper Abdomen Pain. 1  Abdominal Aortic Aneurysm - This condition materializes due to a weak area in the aorta wall. Over time, the wall may rupture due to its weakened condition. As the aorta is the largest artery in the body, this can be a serious condition.
Principles of Motion Sensing. Sensors able to detect three-dimensional motion have been commercially available for several decades and have been used in automobiles, aircraft and ships. However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.
Below is the schematic of the motion sensor light circuit we will build: The schematic diagram of this circuit is: This is the complete schematic of the circuit we will build. We connect pin 1 of the PIR sensor to +9VDC and we connect pin 3 of the sensor to ground.
