Ethylene (C₂H₄) Gas Sensor

Accurate ethylene (C₂H₄) concentration monitoring for crop maturity and physiological condition sensing

Designed for real-time monitoring of ethylene (C₂H₄) released during crop growth, ripening, and aging stages, this sensor continuously and stably detects changes in ambient ethylene concentration with high sensitivity. It helps identify crop maturity progress, physiological stress, and environmental abnormalities. The product is suitable for greenhouses, seedling centers, plant factories, and agricultural research systems. It can work with smart agriculture platforms to provide reliable data support for crop growth regulation, post-harvest management, and intelligent decision-making.

Key Advantages

High Sensitivity

Accurately detects low-concentration ethylene changes to meet the needs of crop maturity signal monitoring in agricultural applications.

High Stability

Suitable for agricultural environments with high humidity and significant temperature variation, offering strong stability and reliability.

Multiple Communication Options

Supports Wi-Fi, RS485, ZigBee, and other communication methods for easy integration into existing agricultural IoT systems.

Smart Coordination and Data Analysis

Can work with ventilation, fresh air exchange, preservation, and control systems to support intelligent crop growth and post-harvest environment management.

Ethylene Sensor

In protected agriculture and large-scale cultivation scenarios, ethylene (C₂H₄) is an important signal gas that reflects crop ripening, physiological changes, and environmental stress. By continuously monitoring trace ethylene concentration in the environment, the ethylene sensor provides real-time insight into crop growth stages and offers critical but otherwise invisible decision support for agricultural management. In greenhouses, seedling centers, and plant factories, the sensor can help determine whether crops have entered rapid ripening or aging stages, and can coordinate with ventilation, fresh air exchange, or control systems to prevent excessive ethylene accumulation from affecting crop quality and yield. In post-harvest management and agricultural research, the ethylene sensor can be used to monitor fruit and vegetable storage and treatment environments, helping optimize preservation strategies and experimental conditions, and enabling refined management from cultivation to post-harvest control.
