The Working Principle and Key Applications of Infrared Sensors
WEBImage Credits: Dario Sabljak/shutterstock.com. An infrared sensor is an electronic instrument that is used to sense certain characteristics of its surroundings. It does this by either emitting or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion.
Automotive Airbag Sensors
WEBJul 27, 2012 — The sensor is positioned inside the engine and a similar safety sensor is located inside the passenger zone of the vehicle. This safety sensor is required to measure the intensity of the collision to determine whether the impact is over a certain threshold to justify the release of an airbag. Both types of sensors (termed inertia sensors) work ...
Comparing Common Methods for Ammonia Gas Detection
WEBFeb 2, 2022 — O₂ + 4 H+ + 4 e– 2 H₂O. EC sensors can enable sensitive and selective analyses of numerous gas-phase species at a rapid time resolution (typically on the order of seconds) and are comparatively lower in cost compared to other sensors. Their compact size also facilitates detection in a diverse range of locations.
What is Oxidation Reduction Potential and How Do ORP Sensors …
WEBNov 2, 2023 — Sponsored by Hamilton Process Analytics Reviewed by Aimee Molineux Nov 2 2023. Oxidation Reduction Potential (ORP) measures the net voltage potential of excess oxidizers or reducers in a liquid. As it is a less common measurement, it can often be misunderstood. It is also referred to as "Redox" since the sensor measures redox reactions.
How Does a Fuel Level Sensor Work?
WEBMar 26, 2019 — Fuel level sensors allow vehicle operators to monitor fuel consumption and determine when to refill the tank. A fuel level sensor consists of two main components: the sensing system itself (also known as the sender) and the indicator (also commonly referred to as the gauge). Fuel level sensors work by measuring the voltage across a variable ...
Accelerator Pedal Position Sensors vs. Throttle Position Sensors
WEBThe accelerator pedal position sensor is also involved in converting the acceleration movement when the pedal is pressed into an electronic signal, which then initiates throttle body control either as opening or closing movements. The accelerator position information is transferred to the throttle actuator control (TAC) module and the ...
What Sensors Are Used in Automatic Doors?
WEBJul 27, 2022 — The Crucial Role of Sensors in Automatic Doors. Sensors in automatic doors detect movement, pressure, or infrared pictures, causing the doors to open or shut. The doors will open as soon as pressure or movement is sensed, and they will shut when the detectors can no longer sense anything. Different kinds of sensors operate in various ways.
What is a Hydrophone? - AZoSensors
WEBJun 20, 2012 — A hydrophone is an underwater microphone designed to monitor underwater noise. A typical hydrophone works by converting a sound wave into an electrical voltage by detecting changes in pressure in the surrounding environment. The speed and distance at which a sound wave travels through water will be …
Motion Detectors - Working Principles and Applications
WEBMotion detectors are primarily used for detecting moving objects (especially people), and gathering data regarding position, acceleration, and velocity. Motion detectors most commonly use an infrared detection sensor, which can be incorporated into various devices found around us. This sensor provides data about motion, using which the device ...
How UV, IR and Imaging Detectors Work - AZoSensors
WEBSensitive parameters. There are other parameters that are more challenging to conquer while they can also interfere, such as the presence of interfering sources, the attenuation by rain, fog, smoke, wind speed on the fire, reabsorption of CO 2 radiation in the optical path, etc.. The response time is related to a particular fire as it often decreases with the distance between the device and ...
