what is potentiometer   potentiometer is a potential divider or we can also say that it is manually adjustable resister with three terminal.Two terminals are connected to resistive element and third one is connected to wiper.wiper position is determines the output voltage. potentiometer has three terminals first and third terminal are connected to a resistive […]

Proximity sensors

    PROXIMITY SENSOR   proximity sensor is a small device which can detect the presence of any nearby object without any physical contact. proximity sensor are more reliable because there is no physical contact between the sensor and  detected object. WORKING PRINCIPLE OF PROXIMITY SENSOR    working principle of the proximity sensor is similar […]

Pressure sensors

What is Pressure sensors      before discuss about the pressure sensor first i want to give you little bit about pressure    what is the mean of pressure ?   pressure is defined as the force applied on a body perpendicular to the body surface (on which the force being applied).so pressure is like […]
