RL78/G22
Multiwavelength Smoke Detector Evaluation Board
1. Introduction
1.1 Scope of this document
The purpose of this Quick Start Guide is to explain the initial settings and procedures required to use the
Multiwavelength Smoke Detector POC board (POC board) and sample software.
The Multiwavelength Smoke Detector is based on a function that combines a smoke chamber with a POC
substrate and uses up to three LEDs (transmit light source) to generate light and a photodiode (receive
photodetector) to detect light. The two elements, the LED and the photodiode, are located at an angle of
about 140 degrees so that the light beam does not fall directly on the photodiode. As ambient smoke enters
the smoke chamber, the transmitted light is scattered with these smoke particles and received by the
detector, which activates an alarm as a fire alarm if it exceeds the set threshold.
1.2 Documents available in the POC

    RL78/G22 Multiwavelength Smoke Detector Evaluation Board 3. POC board setup 3.1 POC board configuration In POC boards, connectors are mounted on the Add-On PCB for debugging. In addition, the Add-On PCB can be separated from the main PCB at the boundary. Depending on the use case, separate the board before use.

E2 Lite Connectivity Figure3-2. Connecting the E2 Lite Emulator (Add-On PCB) Also, if you want to disconnect the Add-On PCB from the main PCB, you can install the program by connecting it via the debug connector on the Main PCB side shown in the Figure3-3.
  • Page 5 RL78/G22 Multiwavelength Smoke Detector Evaluation Board 3.4 Connecting the USB-to-Serial Converter It is possible to connect a USB serial converter and acquire measurement results as A/D conversion values. The USB-to-serial converter connects to the 7Pin connector on the Add-On PCB shown in the Figure3-4.

  • Page 7 RL78/G22 Multiwavelength Smoke Detector Evaluation Board 5. Descriptions and precautions for the use of POC substrate The POC board activates the "indicator LED (red)" as an alarm when smoke is detected. A significant amount of smoke particles is required to activate the alarm. If you want to obtain the measurement result as an A/D conversion value, connect the USB serial converter connected to the POC board to your PC as shown in Figure 5-1.
