Infrared Sensors

Infrared (IR) sensors are devices which detect and measure light with a wavelength in the IR spectrum (>700nm). They are not good at detecting visible light. IR sensors detect light from either external or built-in light sources.
IR sensors use the IR light source to detect and monitor objects or other changes in a particular area.

IR sensor applications:
• Security
• Remote control
• Lighting appliances
• Household appliances
