Solid state carbon dioxide (CO2) sensor
Alphasense
Requires no power
Operates at room temperature
Measures from 2000ppm to 95% CO2
Small size
Low cost
Simple interfacing
Using the potentiometric measuring principle with our patented silver halide solid state electrolyte, this sensor does not have the high power requirement or high price tag of NDIR technology. This sensor is ideal where low cost and low power are critical for CO2 measurement.
This sensor is the result of seven years of research and development work continues. While not as accurate as NDIR and not suitable for IAQ measurements, this sensor is ideal for safety alarms, combustion gas monitoring and high CO2 process monitoring.
Sensor conditioning and evaluation boards are available.
