POWER STORAGE DETAILS Block diagram: The voltage generated by the source (generator) is not of pure dc. This has to be rectified before storage. A diode rectifier then provides a full-wave rectified voltage that is initially filtered by a simple capacitor filter to produce a dc voltage. Block diagram (Power supply) Working principle: The Full Wave Bridge Rectifier Full Wave Bridge Rectifier uses four individual rectifying diodes connected in a closed-loop "bridge" configuration to produce the desired output. The main advantage of this a bridge circuit is that it does not require a special center-tapped transformer, thereby reducing its size and cost. The single secondary winding is connected to one side of the diode bridge network and the load to the other side as shown below. The Diode Bridge Rectifier The four diodes labeled D1 to D4 are arranged in “series pairs” with only two diodes conducting current during each

MOISTURE SENSOR: Sensors are detectors that can measure some type of physical quality that is happening, such as pressure or light. The sensor will then be able to convert the measurement into a signal that one will be able to read. Most of the sensors in use today are actually going to be able to communicate with an electronic device that is going to be doing the measuring and recording. Today, you are going to be able to find sensors in a wide range of different devices that you use regularly. The touch screen that you have on your phone has sensors, and they use pressure sensors for opening the doors at the market. Sensors are a very common part of everyday life. Soil moisture sensors measure the water content in the soil. A soil moisture probe IS made up of multiple soil moisture sensors. Since analytical measurement of free soil moisture requires removing a sample and drying it to extract moisture, soil moisture sensors measure ame other property
