Connecting LP8 CO2 Sensor to Arduino

Our engineers have written a new application note titled: AN162: Connecting the LP8 CO2 Sensor to an Arduino via UART. This document allows you to talk to SenseAir's LP8 miniature CO2 sensor with an Arduino Uno, Mega or Mega2560 microcontroller using a UART TXT-RXD connection. The example Arduino code uses Software.Serial, a library built into the Arduino software. The LP8 sensor...

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...

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...

Oxygen Sensor Used in Nitrogen Generator

IntoN2 manufactures a line of high pressure, high purity nitrogen generators in their factory located in Minden, Nevada. These nitrogen generators are primarily used for laser cutting and specialized manufacturing, but are used in other industries requiring up to 5 nines (0.99999%) of high-purity nitrogen. Because they generate nitrogen, I was curious when IntoN2 began purchasing our TR250Z 25% oxygen...

CO2 Levels at Home

by Mark Lemon, CO2Meter.com Our new SAN-0001 personal CO2 monitor is so small and easy to use, I decided to measure the co2 levels in my home. I wanted see how much carbon dioxide I'm exposed to every day. Of course, I know carbon dioxide at even moderate levels isn't harmful, but the monitor was free and I was curious....

Could Global CO2 Levels be Reduced by Planting Trees?

Could planting trees make enough difference to impact increased CO2 levels on a global level? The idea seems simple enough. Since trees and plants take in carbon dioxide for photosynthesis, theoretically planting enough trees should reduce CO2. The terrestrial biosphere - which includes plants and trees - does have an impact on global CO2 levels. Combined with oceans, the terrestrial...

CO2 Oxygen Sensors on Drone

Reading CO2 and oxygen levels in remote areas can be challenging. That's why we were excited to see CO2Meter’s S8 CO2 sensor and UV Flux oxygen sensor installed on a drone for high-altitude atmospheric testing. The project is the brainchild of RYF Technologies.  Last year, they began testing CO2 sensors to create a handheld CO2 monitor for the Chilean market....
