What is the working principle of image sensor
An image sensor or imager is a sensor that detects and conveys information used to form an image. It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information.
What are image sensors on an alarm
The Image Sensor is a pet immune PIR (passive infrared) motion detector with a built-in camera. The sensor is designed to capture images during alarm or non-alarm events when motion is detected. Users can also initiate image capture on-demand to Peek-In on their property.

What are the uses of image sensor
An image sensor is used to detect & transmit information for making an image. These sensors are used in both analog & digital type electronic imaging devices like digital cameras, imaging tools used in medical, camera modules, night vision tools like radar, thermal imaging devices, sonar, etc.
What are the different types of image sensors
There are two major types of image sensors: CCD, or charge coupled device and CMOS, or complementary metal oxide semiconductor.
What are the basic principles of sensing
There are two main principles of sensing with cantilevers: static and dynamic. Static sensing involves measurement of a change in the static position of the cantilever. For biomolecular detection, surface stress-induced deflection is the most common quantity to be measured.
What is the basic principle of digital imaging
The basic principle, therefore, is to detect X-rays, then convert the X-rays to charge directly or indirectly (via conversion to light as the first step by phosphors or scintillators). These images are processed and viewed digitally.
What are the two types of image sensor
Sensor types : CCD and CMOS
CMOS and CCD are the two most important and common technologies for the image sensor market.
What is a good image sensor
The 35mm full-frame sensor type is the gold standard among professional photographers who want the highest-quality images. The dimensions of a 35mm sensor are typically 36×24mm.
What is image sensor in simple words
An image sensor is a device that allows the camera to convert photons – that is, light – into electrical signals that can be interpreted by the device. The first digital cameras used charge-coupled devices, facilitating movement of the electrical charge through the device so it could be modulated.
What are the four classifications of sensors
All types of sensors can be basically classified into analog sensors and digital sensors. But, there are a few types of sensors such as temperature sensors, IR sensors, ultrasonic sensors, pressure sensors, proximity sensors, and touch sensors are frequently used in most electronics applications.

What are the 2 components of a sensor
Sensors, in their most general form, are systems possessing a variable number of components. Three basic components have already been identified: a sensor element, sensor packaging and connections, and sensor signal processing hardware. However, there are additional components to certain sensors.
What is the range of image sensor
The dynamic range of image sensors
Dynamic range can be described as a ratio but is more often quoted in decibels, or dB. The human eye has a dynamic range of about 100,000:1 or 100dB. The typical dynamic range of a machine vision sensor is around 60dB to 80dB.
What is the most common image sensor
There are multiple varieties of image sensors, but the two most common types of image sensors are 'charge coupled device' (CCD) and 'complementary metal-oxide semiconductor (CMOS) sensors. Charge Coupled Device (CCD): A CCD image sensor is an analog device comprised of cells in a grid.

What are the 2 classifications of sensors
Classification of Sensors
In the first classification of the sensors, they are divided in to Active and Passive. Active Sensors are those which require an external excitation signal or a power signal. Passive Sensors, on the other hand, do not require any external power signal and directly generates output response.
