  • Page 2: Overview

    1. Overview The EM7162 is an evaluation module that permits easy evaluation of the characteristics of the CDM7162 carbon dioxide (CO ) sensor module. The module is equipped with a USB connector to output CO2 concentration measurement data, a terminal for output of the concentration signal in PWM format, and a terminal for output of a voltage signal converted from PWM output.

  • Page 3: Setting The Method Of Serial Communication

    Set the serial communication method by using the communication mode selection switches on the EM7162 module before connecting the USB cable or the power supply. Caution‼ Before changing the serial communication setting, be sure to turn off the power switch (SW1) by setting it to the lower position as shown in Fig.

    5. Using EM7162 with the Measurement Data Management Software After installing the measurement data management software and USB driver (FT232R-USB) on the computer, connect EM7162 to the computer using a mini B-USB cable. In this way, CO concentration and measurement data can easily be collected by the CDM7162 CO sensor module.
  • Page 8 (5) Setting the COM port number [COM No.] Set the number of the COM port to which the EM7162 is connected in "COM No." at the top right of the screen. (for how to check the COM port no., see steps 6~8 in Sec. 4-1).

    - Column B: Measured CO concentration (in ppm) is recorded in order. (4) CO concentration chart created in Excel Figure 11 shows an example where the change in CO concentration is displayed in chart form using the CSV file to which data is saved at a 30 second interval. - Column D: The elapsed time (in seconds) is calculated by multiplying the sampling numbers in Column A by 30.
  • Page 12 Figure 12 - Display example during Air Adjustment Procedures for Air Adjustment: (1) Change the Air Adjustment setting value to assumed CO2 concentration in ambient air (420ppm in the example shown in Figure 12) on the PC display. Then click [Set] button. (2) Confirm that the CDM7162 CO2 sensor output has been sufficiently stable under this ambient conditions, and click [Calibration] button.
