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...

Use Python to Talk to CO2 Probe

Recently we had a customer contact us regarding opening a serial connection via Python to our CM-0039 CO2 Probe. The Probe is a ruggedized enclosure for our SenseAir CO2 sensors that allow USB tethered, real-time reading of CO2 levels from a PC. While we don’t have any pre-written Python code to talk to the Probe, with a bit of work, the customer should be able to do it on his own. The same is true for any programming language that will let you communicate with a serial device. The first thing to do is to verify that the hardware is...
