Sensor Type

Sensors are devices that detect and respond to a physical stimulus. They play a crucial role in various fields, from industrial automation to personal electronics. Here are some of the most common types of sensors:

Physical Sensors

• Temperature Sensors: Measure temperature (e.g., Thermocouples, RTDs, thermistors).
• Pressure Sensors: Measure pressure (e.g., Strain gauge, piezoelectric sensors).
• Position Sensors: Measure position or displacement (e.g., Potentiometers, encoders).
• Force Sensors: Measure force or weight (e.g., Load cells, strain gauges).
• Vibration Sensors: Detect vibrations (e.g., Accelerometers).

Environmental Sensors

• Light Sensors: Measure light intensity (e.g., Photodiodes).
• Humidity Sensors: Measure humidity (e.g., Capacitive, resistive sensors).
• Gas Sensors: Detect specific gases (e.g., Semiconductor, electrochemical sensors).
• Flow Sensors: Measure fluid flow rate (e.g., Ultrasonic, vortex flow meters).
• Level Sensors: Measure levels of fluids or solids (e.g., Ultrasonic, radar sensors).

Motion Sensors

• Accelerometers: Measure acceleration, used in phones, fitness trackers.
• Gyroscopes: Measure angular velocity, used in drones and VR.
• Magnetometers: Measure magnetic fields, used in navigation.

Imaging Sensors

• Image Sensors: Capture images or videos (e.g., CMOS, CCD).
• Infrared Sensors: Detect infrared radiation (e.g., Thermal imaging cameras).

Other Types

• Chemical Sensors: Detect specific chemicals.
• Biomedical Sensors: Monitor physiological signals.
• Radiation Sensors: Detect radiation levels.
