PIR SENSOR: Every living object emits thermal radiation. Infrared radiation depending upon the temperature of the body, which is detected by the sensor. Suppose a sensor initially faces something when a human body passes in front of it. Its temperature rises and then drops as the body temperature is higher than room temperature. This phenomenon […]

As per caveats of UNO ‘Electricity for lighting accounts for almost 20% of electricity consumption and 6% of CO2 emissions worldwide. According to the International Energy Agency, approximately 3% of global oil demand can be attributed to lighting. If not addressed immediately, global energy consumption for lighting will grow by 60% by the year 2030.

A Semiconductor diode is a two-terminal electronic device which conducts current in one direction. it has almost zero resistance in one direction, and very high resistance in the other. most commonly used semiconductor diode today, is a crystalline piece of semiconductor material with a P–N junction. To metal terminals are connected to two Semiconductor blocks.

Light Depending Resistor or Photo Resistor LDR or Light Depending Resistor or Photo Register is an important device in electronics today. It is used to sense the intensity of light as the resistance of the LDR is changed in terms of change in light.When the light fall on a LDR it’s resistance goes low. When

Resistance If you want to construct an electronics project at you must have to know the use of Resistance. You can understand the function of resistance from ohm’s law. If Resistance (R)= Voltage across the resistance (V) / Current passing through the resistance (I), i.e. R=V/I this equation answers all questions, Why, How, when we
What is Voltage?, What is Current?, What is Power? When we connect a device in to the circuit we must understand the Voltage, Current and Power issues related to the circuit and device. We must not connect a 1/4 watt resistance in 2volt 1Amp circuit. To understand those pleas go through till end of the
