  • Applications of IR Sensor
  • IR Imaging Devices
  • IR image devices are one of the primary applications of IR modules, primarily because of their property that is not visible. We used it for thermal imagers, etc.
  • Security Devices
  • Since the IR module works for infrared radiation, therefore, it may be utilized in some Security devices. The transmitter transmits, and the receiver receives the waves. When something comes between these waves, the receiver gives the signal forward to the circuit.
  • Other Applications
  • Flame monitors
  • Obstacle detection devices
  • Robotics
  • Gas detectors
  • Gas analyzers, etc
