Humidity sensor- types of humidity

 HUMIDITY SENSOR                                               humidity sensor is nothing but a device which can measure the amount of water or moisture present in air.this is also known as HYGROMETER. BEFORE GO FAR I WANT TO TELL SOME IMPORTANT ABOUT THE HUMIDITY   1.their is  a important point to remember that the amount of moisture present in air […]

potentiometer

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 […]

Temperature sensors

TEMPERATURE SENSOR As we discuss earlier about the sensor and according to that knowledge we know that sensor is a device which can check the change in environmental conditions.   the temperature sensor is a device or thermocouple  which can measure the temperature of  required system in some different measurable quantity(voltage) .these measurable quantity are […]

IR sensor

sensors sensor is a device which  is able to detects the  change  in the ambient condition.sensors used for an element which produces a signal relating  to the quantity being measure. for example  … an electric resistance temperature element ,the quantity being measured  is temperature and sensor transform an input of the temperature into a change […]
