Product Description:

YJJ CO-AM Electrochemical Carbon Monoxide Sensor (CO sensor) Is Used In Fields Such As Coal Mines

Features:

In facility agriculture, the concentration of carbon dioxide (CO₂) is a key environmental factor that affects the efficiency of plant photosynthesis. The Alphasense CO-AM carbon monoxide sensor in the UK is actually a high-precision gas sensor (here focusing on its CO₂ monitoring function). With its high sensitivity and anti-interference ability, it has become a crucial equipment for environmental monitoring in agricultural greenhouses. By accurately capturing the dynamic changes in CO₂ concentration, it provides scientific regulation basis for crop growth and promotes the intelligent upgrade of agricultural production. The Alphasense carbon monoxide sensor CO-AM in the UK has strong anti-interference ability.

The quantitative relationship between CO₂ concentration and photosynthesis

The response of plant photosynthesis to CO₂ concentration exhibits a significant threshold characteristic. When the CO₂ concentration is raised from the atmospheric baseline value (approximately 400 ppm) to 1000 ppm, the photosynthetic rate of C₃ plants (such as wheat and rice) can increase by 30%-50%, while the response threshold for C₄ plants (such as corn) is even higher. The CO-AM sensor, based on electrochemical principles, converts the CO₂ concentration into a linear electrical signal output. Its measurement range covers 0-5000 ppm, with a resolution of 1 ppm, and can accurately capture fluctuations in CO₂ concentration. In a tomato greenhouse, when the sensor detects a CO₂ concentration below 800 ppm, the system can automatically trigger a supplementary device to increase the concentration to 1200 ppm, thereby increasing the fruit sugar content by 15%-20%. The British Alphasense carbon monoxide sensor CO-AM has strong anti-interference capabilities.

The collaborative mechanism of dynamic monitoring and intelligent regulation

The core advantage of the CO-AM sensor lies in its millisecond response speed and long-term stability. In a closed greenhouse environment, the CO₂ released by the nocturnal respiration of plants can cause the concentration to suddenly rise above 1500 ppm, while the consumption of photosynthesis during the day will lead to a rapid decrease in the concentration. Through dual-channel sampling technology, it can distinguish between environmental background interference and concentration changes in real time, with a false alarm rate of less than 0.1%. In a strawberry planting greenhouse, the sensor is linked with an intelligent ventilation system. When the CO₂ concentration exceeds 1800 ppm, the exhaust fan is automatically turned on, and when it drops below 600 ppm, a liquid CO₂ cylinder is activated to replenish, controlling the fluctuation range of the concentration throughout the day within ±100 ppm, resulting in a 25% increase in yield.

Anti-interference capability in extreme environments

The high humidity and high dust environment of agricultural greenhouses pose challenges to sensor performance. The CO-AM sensor adopts anti-fouling filter membranes and hydrophobic coating technology, maintaining measurement accuracy even at 90% RH humidity. In mushroom cultivation greenhouses, organic gases produced by mycelial metabolism may interfere with traditional sensors, but the CO-AM effectively suppresses cross-gas interference through a three-electrode design, controlling the CO₂ concentration monitoring error within ±3%. It supports operation in a wide temperature range of -20°C to 50°C and can still work stably in northern winter greenhouses. The British Alphasense carbon monoxide sensor CO-AM has strong anti-interference capability.

Data-driven precision agriculture practices

The CO₂ concentration data collected by the CO-AM sensor can be integrated into the agricultural Internet of Things platform. Combined with parameters such as light intensity, temperature, and humidity, a crop growth model can be established. In a cucumber greenhouse, by analyzing the coupling relationship between CO₂ concentration and photosynthetically active radiation (PPFD), the system can dynamically adjust the CO₂ supplementation strategy: when PPFD is higher than 1000 μmol/m²·s, the CO₂ concentration is maintained at 1200 ppm; when PPFD is lower than 500 μmol/m²·s, the concentration is reduced to 800 ppm. This data-driven regulation method increases fertilizer utilization by 18% and reduces water consumption by 22%. The British Alphasense carbon monoxide sensor CO-AM has strong anti-interference ability.
