This is why the best data acquisition systems haveisolated inputs- to preserve the integrity of the signal chain and ensure that what the sensor outputs is truly what has been read. There are several kinds of isolation techniques employed today. ...
The control box is hooked up to one or more alarm circuits, but it also has its own power supply. It monitors the circuits and sounds the alarm when they are closed or opened (depending on the design). But once the alarm is triggered, the control box won't cut it off until somebody...
Semiconductors are of 2 Types:An N-type semiconductor is one that carries current in the form of negatively-charged electrons. This is very similar to conduction of current in a wire. A P-type semiconductor is one that carries current predominantly as electron deficiencies called holes. A hole...
Depending on the severity of the shock, the brain signals a warning horn beep or sounds the full-scale alarm. There are many different ways to construct a shock sensor. One simple sensor is a long, flexible metal contact positioned just above another metal contact. You can easily configure ...
2. What are common reasons for the check engine light to come on in an Audi? Common reasons include issues with the oxygen sensor, catalytic converter, mass airflow sensor, ignition coils, spark plugs, or fuel cap. Each of these components plays a vital role in your vehicle’s performance...
Its resistance decreases with an increase in the intensity of light. It is often used as a light sensor, light meter, Automatic street light, and in areas where we need to have light sensitivity. LDR is also known as a Light Sensor. LDR are usually available in 5mm, 8mm, 12mm, and ...
The heavy cable is replaced with lightweight 2-wire CAN in today’s cars and trucks How does CAN messaging work? Devices on a CAN bus are called “nodes.” Each node consists of a CPU, CAN controller, and a transceiver, which adapts the signal levels of both data sent and received by...
Not surprisingly, people are absolutely obsessed with protecting their hard drives; it’s like a bank safe for your computer! Power Supply Power supply inside a computer cabinet (Image Source: www.sensorx.co.in) Also known as the SMPS – Switched Mode Power Supply, or PSU – Power Supply ...
However, it is important to keep in mind, that just because a part is reading bad on the computer, it doesn’t necessarily mean that part is bad. A broken or damaged wire can cause the part to not send the proper signal. If a sensor or part is reading bad, be sure to visually ...
There are distinct categories of glass-seal hermetics: Matched and mismatched (or compression) seals. Matched seal hermetics have a relatively limited thermal expansion and contraction of the glass and metal materials (usually within 10% of each other), which limits resulting the stress on the glas...
