Permafrost Study Uses K-30 Sensors

Researchers are studying permafrost in Alaska to get long-term data on the release of carbon dioxide as the result of weather changes. The team is led by Dr. Houston Miller, Professor of Chemistry at the George Washington University. It includes GWU students, researchers from NASA Goddard Space Flight Center and the University of Alaska, Fairbanks.  Funded by a grant from NASA's Terrestrial Hydrology Program, the team is combining satellite measurements, climate modeling, and ground-level measurements of greenhouse gas concentrations during seasonal permafrost melting seasons. According to Dr. Miller, “[Our project is] a multi-disciplinary, multi-scaled study to measure methane (CH4) and carbon dioxide...

K-30 CO2 Sensor Troubleshooting with Arduino or Raspberry Pi

Customers using SenseAir's K-30 CO2 sensor with an Arduino micro controller or the Raspberry Pi occasionally see the sensor "lock up" during use. It appears that the sensor sends negative data and quits working. After unplugging the sensor from power momentarily, it works again. This seems to be a random problem. Fortunately, we have been able to recreate the problem, and have several solutions. Low Power The most common issue is power. 5VDC is the absolutely required minimum voltage. If you are powering from a USB port, the nominal 5.25V will drop with other USB devices on the circuit, causing an error. If...

CO2 Sensors and Raspberry Pi

Our engineers have created application notes to connect two of CO2Meter’s most popular CO2 sensors with the popular Raspberry Pi. The Raspberry Pi is a credit-card-sized computer that plugs into a monitor and keyboard. It makes it easy for hobbyists to create projects for a very low cost. COZIR CO2 Sensor This app note AN-127 explains how to connect the Raspberry Pi 3 with the COZIR CO2 sensor via UART. Includes step by step instructions. AN127 Instructions here (pdf). AN127 project source code here (zip).   K-30 CO2 Sensor This app note AN-137 explains how to connect the Raspberry Pi 3...
