Simple Tilt Sensor Switch Circuit A tilt sensor is a sensor which opens and closes an electrical circuit when it is inclined beyond at certain angle. It can be used in tilt prevention devices, an alarm circuit and in many DIY projects. There are different types of Tilt sensor modules, for sensing the tilt the module can have a ball switch or mercury switch. In this circuit, we are using a Mercury-based tilt… |

What is Thyristor and How it works? In general, Thyristors are also switching devices similar to transistors. As we already discussed, Transistors are the tiny electronic components that changed the world. Today we can find them in every electronic device like TVs, mobiles, laptops, calculators, earphones, etc. They are adaptable and versatile, but that doesn’t mean that they can be used in every… |

Transistor as an Amplifier Circuit Transistors are the semiconductor devices used for switching or amplifying electrical signals. They are highly durable, smaller in size and operates on a low voltage supply. A Transistor is a three terminal device: Base: This pin used for activating the transistor (minimum 0.7V required to turn ON a Transistor) Collector: Current flow through… |

Transistor Switching Circuit: Examples of How Transistor Acts as a Switch Transistors are made up of semiconductor material which is most commonly used for amplification or switching purpose, although they can also be used for controlling the flow of voltage and current. Not all but most of the electronic devices contain one or more types of transistors. Some of the transistors placed individually or else generally in integrated circuits… |

PIR Sensor Based Motion Detector/Sensor Circuit Passive Infrared Sensor (PIR) is very useful module, used to build many kinds of Security Alarm Systems and Motion Detectors. It is called passive because it receives infrared, not emits. Basically PIR sensor detects any change in heat, and whenever it detects any change, its output PIN becomes HIGH. They are also referred as Pyroelectric or IR motion sensors. … |
