    CO2 sensorCO2 sensors for greenhouses in smart agriculture applications

    Products with long-term stability and high measurement accuracy that promise to improve maintainability.

    Excellent temperature characteristics make them well suited to high-humidity environments, such as greenhouses with large daytime temperature fluctuations.

    The low drift inhibits excessive petroleum fuel usage and is able to achieve increased yields through stable CO2 application.

    Environmental durability has been improved through the use of a moisture-proof coating and a high-performance air filter, and it includes a built-in surge protection power circuit.

    Challenges in agriculture and greenhouses, and Murata’s strengths

    Challenges in agriculture and greenhouses

    • The CO2 concentration required for plant photosynthesis varies by crop and season; therefore, the challenge is to maintain constant CO2 concentrations.
    • Accurate measurements are necessary because the accuracy of CO2 sensors and environmental conditions such as humidity and temperature can cause measured values to fluctuate.
    • Yields suffer when measured values are higher than the true values.
    • Loss of energy (fuel costs) occurs when measured values are lower than the true values.
    • Manually calibrating CO2 sensors requires removing them or opening greenhouses, increasing loads.

    Strengths of Murata CO2 sensors

    Murata’s CO2 sensors use the dual-beam NDIR method for accurate measurements even at atmospheric concentrations below 400 ppm. Accurately measuring CO2 concentrations and supplying CO2 at the right times helps improve crop yields and quality.
    In addition, with our unique mechanism and algorithms, our CO2 sensors are self-calibrating when measured values start to stray, making them maintenance-free and stable over the long term.
    Our lineup includes a model with an easily installable case and cable designed for agricultural applications, in addition to modular products for system integration.
