The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Typical uses include measuring liquid or gas flow in pipes or ducts, or detecting a blockage or seized valve. The sensor transforms these variations into a Our sensor e-books are designed to help you learn about how to choose various sensors: pressure sensors, ceramic pressure sensors, humidity sensors, mass flow sensors.

Such a flexible polymer TEG gives an output voltage of up to 3.3 V at a power density of 10.4 mW/cm 3. Such a flexible polymer TEG gives an output voltage of up to 3.3 V at a power density of 10.4 mW/cm 3. For more on differential pressure measurement, click the button below to jump to chapter five. A capacitor is a device that stores electrical energy in an electric field.It is a passive electronic component with two terminals.. A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine.. Nanosensors are platforms with a characteristic dimension - nanometer in scale, and work in much the same way as a sensor; they detect either minute particles or miniscule quantities of something. A microphone, colloquially called a mic or mike (/ m a k /), is a transducer that converts sound into an electrical signal.Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and . Chlorine Residual Sensor: It measures chlorine residual (i.e. MOS technology is the basis for modern image sensors, including the charge-coupled device (CCD) and the CMOS active-pixel sensor (CMOS sensor), used in digital imaging and digital cameras. A differential pressure sensor (see diagram to the right) measures the difference between pressure experienced at two exposed ports. YFS201 Hall effect sensor is an example of this sensor.
