this is known as baseload cycling and its cost ranges from $ 2 to $ 23 per megawatt hour this also reduces the environmental friendliness of wind power because a coal fired or natural gas power plant must be kept online in case there s no wind two plants are running to do the job of one
Accelerometer in an iPhone. Definition: An accelerometer is a sensor which measures the tilting motion and orientation of a mobile phone. The Apple iPhone was the first popular mobile phone to make the accelerometer a key feature of its user interface. The accelerometer is used to ensure photographs are presented in the correct way - portrait or landscape - depending on the way the phone is held. Accelerometers are also increasingly used as a means of user input, most noticeably in games where tilting and rotating the handset can control onscreen action.
Bookmark with: The three most common motion sensors used in technology today are PIR, Ultrasonic and Radar. Ultrasonic uses sound to detect motion and Radar detects pulses. The third, most commonly used, (and also used in our Mr. Beams Motion Sensing LEDs) is PIR motion sensors, which detect heat. If you live almost anywhere in the US, it's likely you have experienced major heat waves this summer and a few may notice a slight change in the range of your Mr. Beams Motion Sensor Light.
