Reference Design of RENESAS Smoke Detector

This is a reference design of the RENESAS smoke detector, which is one of the example solutions available using RL78 / I1D. It is in a format that you can use with our free DesignSpark PCB software to edit and use freely as required. Please refer to the end of this article for downloads of the RENESAS Smoke Detector project files.

 

The RENESAS smoke detector is a board that can detect smoke in the air. The RL78 / G1D microcontroller, which can be mounted on this board, is suitable for sensor applications such as detectors because it can operate with low power consumption and high-speed wakeup. In addition, the RENESAS smoke detector does not only detect smoke, but can also be used for temperature sensing, light sensing, or other types of detector.

Key features

  • Detect smoke in the air indicating a fire
  • Operate with low power consumption
  • High speed wake up possible
  • Other detectors can be created

It can detect smoke,but i´d like to know if it can detect a percentage of smoke or if it only can read high or low.
Congratulations on the great article.
