Weekly Progress
Overall : In this week, I went to learn at Bangkungtian. In the morning, I learn about the PCB
program. In the afternoon, My company is interest about measure CO2 (Carbon Dioxide) gas. So, I
was going to study about measure CO2 (Carbon Dioxide) gas sensors.
Engineering Knowledge : I has searched about measure CO2 (Carbon Dioxide) gas sensors. The
CO2 (Carbon Dioxide) Gas Sensor is used in gas detection equipment for detecting Carbon Dioxide
gas in home. It has stable and long life and high sensitivity to Carbon Dioxide gas. In the Application,
It can air quality control and Fermention process control.And the Key Specifications:
- Power requirements: 6.5 - 12 VDC @ ~160mA (~2mA in standby mode)
- Interface Type: High-Impedance EMF Generation
- Dimensions: 0.70" diameter x 0.60" tall excluding leads (17.8mm diameter x 15.2mm tall
excluding leads)
- Operating temp range: -4 to +122 °F (-20 to +50 °C)

Engineering Analysis
Strong Point
- High sensitivity to Carbon Dioxide gas.
- Stable and long life.
Week Point
- CO2 (Carbon Dioxide) gas sensors gas sensor has expensive.
Next Week Job
- I will learn about how to detect humidity.
