Following the manufacturer's proper oxygen sensor storage and operating conditions are critical to long sensor life.

CO2Meter has worked closely with universities nationwide that continue to use our sensor technologies to gather data for scientific research, discovery, and advancements.

Updates Our engineering team has rewritten the application notes to connect the Arduino Uno, Mega or Mega2560 microcontrollers with two of our most popular CO2 sensors.   AN-126 – Arduino UART Interface to K-30 Sensor The AN-126 – Arduino UART Interface to K-30 Sensor and included source code (zip) gives you step by step instructions for connecting SenseAir’s K-30 CO2 sensor using an industry‐standard UART TXD‐RXD connection. Wiring diagrams are included.   AN-128 – Arduino UART interface to COZIR Sensor The AN-128 – Arduino UART interface to COZIR Sensor and included source code (zip) gives you step by step instructions for connecting...

CO2 sensors use a barometer for altitude compensation to account for the change in barometric pressure. A customer called recently and said we had sold him a defective CO2 sensor module. He had calibrated it precisely at 0.0ppm (zero parts-per-million), took it outside, and the sensor read 335ppm. “Where do you live?” we asked. “Colorado,” he replied. It took a few minutes to explain, but in the end the customer understood that altitude makes a difference when you are measuring carbon dioxide levels. CO2 sensor modules are calibrated at sea level. Most are not designed to automatically compensate for changes...
