Outline/Features

This solution uses pyroelectric motion sensors to detect the movement of persons. Two sensors are used to allow detection of the direction of movement. The microcontroller's on-chip low-power op-amp reduces the system cost.

Configuration
  • Microcontroller: RL78/I1D low-power analog microcontroller
  • Solution board: RL78/I1D Detect it! motion detector board
