What is Magnetic Sensor : Types, Working & Its Applications
Magnetic sensors are the sensors that convert the change/ magnitude of a magnetic field into an electrical signal. The Earth's magnetic field or the magnetic field referred to as magnetism, is a well-known but invisible phenomenon. Magnetic sensors convert invisible magnetic fields into electrical signals and help to have visible effects. They were designed decades ago as a sensor using the electromagnetic induction effect and has expanded into applications in the magneto-resistance effect, … [Read more...]
Interfacing Knock Sensor to a Microcontroller or Arduino
Generally, automobiles (especially 2-wheeler and 4-wheeler vehicles) and security monitoring systems are equipped with multiple sensors that constantly monitor their operation and condition. Some sensors measure air, oxygen, and temperature, while others, such as knock sensors, measure vibration and noise levels in the vehicle's engine and security monitor systems. Knock sensors, on the other hand, have a much wider range of applications and are also known as piezoelectric sensors Or vibration … [Read more...]
Knock Sensor : Circuit, Working, Testing, Types, Failure Causes & Its Applications
In automobiles, engine knocking is a sound or detonation or engine ping that occurred due to high-frequency vibrations caused by poor quality fuel, wrong spark plug, irregular ignition /explosion occurring in the cylinder, and deposits on the cylinder wall. These engine knocks can cause power wastage of the engine and destroy the engine. These days, modern vehicles are equipped with various sensors to monitor their functioning like measuring the air, temperature, etc. In addition to these, the … [Read more...]
