BREIF KNOWLEDGE OF SENSORS

1. SENSORS

2. SENSORS
• A sensor is a device that detects the
changes in electrical or physical or other
quantities and thereby produces an output
based on the pre-set values entered or the
current conditions
• It is a device that converts signals from
one energy domain to electrical domain.

3. • Photoelectric, Thermoelectric,
Electrochemical, Electromagnetic,
Thermooptic
• Electric, Biological, Chemical, Radioactive

4. TYPES OF SENSORS
• Temperature Sensor
• Proximity Sensor
• IR Sensor (Infrared Sensor)
• Pressure Sensor
• Ultrasonic Sensor
• Smoke, Gas and Alcohol Sensor
• Touch Sensor
• Humidity Sensor

5. OPTICAL SENSOR
• Electro-optical sensors are electronic
detectors that convert light, or a change in
light, into an electronic signal.

6. MULTISPECTRAL SCANNER
(MSS)
• A scanning system used to collect data over
a variety of different wavelength ranges is
called a multispectral scanner (MSS)

7. LISS
• Linear Imaging Self-Scanning Sensor -
LISS III is a remote sensing satellite
camera from ISRO, India.
• The LISS – III camera provides
multispectral data in 4 bands.

8. WIDE FIELD SENSOR
• Wide Field Sensor are use for detecting
and capturing a wide view of pariticular
area.
• This type of sensors are mailny used in
different seasons to detect

9. PAN SENSOR
• Single channel (panchromatic) imager
producing better than 10 m ground
resolution.
• Sensitive to light of all colors in the visible
spectrum panchromatic film.
