Infrared calibration technology empowers intelligent monitoring! The new generation of RS485 CO2 temperature and humidity sensors leads the upgrading of agricultural environmental monitoring

January 05 , 2026

With the rapid development of facility agriculture and smart farming industries, precise environmental parameter monitoring has become a critical factor in boosting productivity and ensuring quality. Real-time control of CO₂ concentration, temperature, and humidity directly impacts crop photosynthetic efficiency and growth cycles. Recently, the RS485-type CO₂ temperature and humidity sensor equipped with next-generation infrared calibration technology has been officially launched. With its advantages of high stability, long lifespan, and strong adaptability, it offers a new solution for environmental monitoring in agricultural cultivation and facility horticulture.

Technological Innovation: Breaking through the Bottleneck of Traditional Sensors

Traditional CO₂ monitoring devices mostly use electrochemical sensors, which generally have problems such as short lifespan, obvious long-term drift, and significant influence by temperature. They require frequent calibration and replacement, increasing operation and maintenance costs as well as monitoring errors. The new sensor innovatively adopts infrared calibration technology, fundamentally solving this industry pain point — it not only has fast response speed and high sensitivity, but also achieves the core advantages of low drift and long lifespan. In a 25℃ environment, the CO₂ measurement accuracy can reach ±(45ppm +3% F・S) (high-precision version), and the temperature and humidity measurement accuracies reach ±0.5℃ and ±3% RH respectively, fully meeting the precise monitoring needs of professional planting scenarios.

In terms of measurement range, the sensor offers flexible options: the default CO₂ measurement range is 0-5000ppm, with optional versions of 0-2000ppm or 0-10000ppm. The temperature and humidity measurement ranges cover -40℃~+80℃ and 0~100% RH respectively. Equipped with a built-in temperature compensation function, it can maintain data stability even in scenarios with drastic changes in ambient temperature, with a non-linear error of less than 1% F・S.

Adaptability upgrade: balancing convenience and adaptability to harsh environments

In response to the complex installation and usage environments at agricultural sites, this sensor has achieved multiple optimizations in its design. In terms of communication, it adopts the standard ModBus RTU protocol and supports multiple baud rate options such as 2400bit/s, 4800bit/s, and 9600bit/s (the default factory setting is 4800bit/s). The maximum communication distance can reach 2000 meters, allowing for easy integration into multi-device bus systems. Moreover, the device address supports custom settings within the range of 1-254 to avoid address conflicts.

The power supply and protection design also meet on-site requirements: it uses a 10-30V wide-voltage DC power supply, with an average current of less than 85mA and a power consumption of only 0.3W (24VDC), making it compatible with power supply systems in different scenarios; the shell adopts a wall-mounted waterproof structure with a high protection level, enabling stable operation in harsh environments ranging from -20℃ to +60℃ and 0% RH to 95% RH (without condensation), perfectly suitable for various scenarios such as agricultural greenhouses, open-air sheds, and edible fungi cultivation rooms. The installation process is also extremely simple, equipped with a full set of accessories such as self-tapping screws and expansion plugs. Wall mounting can be completed by drilling a 5mm diameter hole for fixation, without the need for complex debugging.

Feature Expansion: Supports custom configuration and smart linkage

In addition to its core monitoring functions, this sensor also features rich expandability to meet personalized needs. The device has multiple built-in readable and writable registers, supporting the modification of temperature, humidity, and CO₂ upper and lower limit alarm values as well as calibration values through function codes such as 0x06 (the calibration value needs to be expanded by 10 times when writing). Users can set exclusive monitoring thresholds according to the growth needs of different crops to realize timely early warning of abnormal situations.

For smart agricultural systems that require multi-parameter integration, the sensor offers two version options: single CO₂ monitoring and integrated temperature, humidity + CO₂ monitoring. The integrated version can read three core data of temperature, humidity, and CO₂ through a single command, with a data update cycle of only 2 seconds. Combined with CRC (Cyclic Redundancy Check) verification, it ensures the accuracy and integrity of data transmission, provides reliable data support for IoT platforms and PLC control systems, and helps realize intelligent control functions such as automatic ventilation, fertilization, and irrigation.

Application scenarios: meeting the needs of full-scenario agricultural planting

The launch of this sensor will be widely applicable to various scenarios such as agricultural greenhouses, flower cultivation, edible fungi planting, and seedling nurseries. In edible fungi cultivation, excessively high CO₂ concentrations can inhibit mycelial growth. By real-time monitoring with the sensor and linking it with ventilation equipment, the CO₂ concentration can be controlled within the optimal range. In flower greenhouses, precise regulation of temperature, humidity, and CO₂ can extend the flowering period and improve flower quality. In large-scale agricultural bases, networked monitoring with multiple devices can realize visual management of environmental data across the entire area, providing a scientific basis for planting decisions.

Industry significance: Helping upgrade agricultural monitoring to intelligentization

Currently, smart agriculture is developing towards the direction of "precision, automation, and low cost". As a data collection terminal, the performance of environmental monitoring equipment directly determines the operating efficiency of intelligent systems. Through technological innovation and scenario adaptation, this RS485-type CO₂, temperature and humidity sensor not only solves many pain points of traditional equipment, but also reduces the threshold for intelligent transformation of small and medium-sized growers and large-scale bases with the advantages of high cost performance and easy integration.

In the future, with the in-depth integration of IoT technology and agricultural production, such high-precision and high-stability monitoring equipment will become the core infrastructure of smart agriculture. The launch of this sensor not only fills the market gap in medium and high-end agricultural environmental monitoring equipment, but also promotes the transformation of facility agriculture from "experience-based planting" to "data-based planting", injecting new impetus into agricultural production capacity improvement and sustainable development.

In practical applications, users should avoid installing the equipment in a strong convective air environment or in contact with organic solvents and corrosive gases. At the same time, ensure that the 485 bus A/B lines are connected correctly. When networking multiple devices, reasonably set the addresses and communication parameters to give full play to the performance advantages of the equipment.https://www.zonewuiot.com/gas-sensors_c11
