Humidity Sensors Humidity Humidity is defined as the water vapor content in air or other gases. Humidity is usually measured in terms of absolute humidity (the ratio of the mass of water vapor to the volume of air or gas)‚ dew point (the temperature and pressure at which a gas begins to condense into a liquid)‚ and relative humidity‚ or RH (the ratio of the moisture content of air compared to the saturated moisture level at the same temperature or pressure).

RESEARCH: SENSORS ULTRASONIC RANGE FINDER An ultrasonic range finder sensor enables a robot to detect obstacles in its path by utilizing the propagation of high-frequency sound waves. The sensor emits a 40 kHz sound wave‚ which bounces off a reflective surface and returns to the sensor. Then‚ using the amount of time it takes for the wave to return to the sensor‚ the distance to the object can be computed. Unlike the bumper switch and limit switch that alert you when they have been hit‚ the ultrasonic

SENSORS AND INTERFACING BY S. Muhammad Raza RF POWER AMPLIFIER: An RF power amplifier is a type of electronic amplifier used to convert a low-power radio-frequency signal into a larger signal of significant power‚ typically for driving the antenna of atransmitter. It is usually optimized to have high efficiency‚ high output Power(P1dB)compression‚ good return loss on the input and output‚ good gain‚ and optimum heat
