Various Sensors Used in Smart phones Nowadays

  • Proximity Sensor: Recognizes whether the mobile phone is located near to the user or not by sending Infrared rays.
  • Gesture Sensors: It will look for your gesture movements, mainly eyes or hand and act accordingly.
  • RGB Light Sensor: Measure the red, green, blue and white intensity of the light source, used mainly to make adjustments in the Cameras.
  • Gyro Sensor: Used to detect the mobile phone rotation state based on three axis
  • Accelerometer: Detects the orientation of phone according to three axes. This sensor is widely used in all portable gadgets.
  • Geomagnetic Sensor: Used in Maps to detect directions by detecting magnetic field intensity.
  • Temperature/Humidity Sensor: Checks temperature and humidity levels.
  • Barometer: Identifies the atmospheric pressure at the user’s current location.
  • Hall Sensor: Recognizes whether the cover is open or closed.
  • Motion Sensor: Which detects the motion of Phone, especially for gaming and unlocking phones
  • Ambient Light Sensor: To check the intensity of light in the atmosphere and adjust display brightness accordingly.
  • Gravity Sensor: It’s usually an accelerometer which contains a weight or tube inside. So moving of this weight tells the phone whether it moves right or left, top or bottom, up or down. It works mainly during gaming.

Complete review on new Moto E (2nd generation)

Build Quality Feels great in the hand, the smaller size & curved back definitely makes for great one-handed usage.

The buttons are a bit stiff, which i personally liked as they didn't get pressed easily in the pocket or while watching videos. Aside from that no major gripes so far, Very good build quality. Display The display isn't great any any means, It has a yellow-ish/brown-ish thinge throughout and the brightness is average.

UI & Usability Phone is amazingly smooth and Loliipop is a treat to use. Moto E's biggest advantage has to be the lack of bloat and the clean skin they've adopted. So far everything has been runnin

Some Facts about Electric Vehicles

All-electric vehicles (EVs) run on electricity only. They are propelled by an electric motor (or motors) powered by rechargeable battery packs. EVs have several advantages over vehicles with internal combustion engines (ICEs): ·          Energy efficient.  Electric vehicles convert about 59–62% of the electrical energy from the grid to power at the wheels—conventional gasoline vehicles only convert about 17–21% of the energy stored in gasoline to power at the wheels. * ·          Environmentally friendly.  EVs emit no tail pipe pollutants, although the power plant producing the electricity may emit them. Electricity from nuclear-, hydro-, solar-, or wind-powered plants causes no air pollutants. ·          Performance benefits.  Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than ICEs. ·          Reduce energy dependence . Electricity is a domestic energy source. EVs do, however, face significant battery-related c
