We all love servos, we love them with breakfast, lunch and dinner. But one serious concern that arises is when we include other noisy components and interference gets in the way. This problem is compounded to extreme when you introduce distance. The further you get from the PWM source the greater the signal is degraded […]
Each body with a temperature above the absolute zero emits an electromagnetic radiation, which is proportional to its intrinsic temperature. A part of this intrinsic radiation is infrared radiation, which can be used to measure a body’s temperature. The devices that measures infrared electromagnetic radiation and converts it to the temperature are so-called non-contact thermometers.
