Renke CO2 Sensor Types
RS-CO2*-*-2-*-EX
The RS-CO2*-*-2-*-EX is a wall-mounted carbon dioxide sensor available with optional RS485, 4-20mA, 0-5V, or 0-10V output. It overcomes the lifespan and long-term drift issues associated with traditional electrochemical sensors and is widely used in greenhouses, industrial production facilities, and buildings. This CO2 sensor features built-in temperature compensation and is minimally affected by temperature fluctuations. For real-time on-site data viewing, an OLED display (priced at $10.50) can be added.
RS-CO2*-*-2D-EX
The RS-CO2*-*-2D-EX was specifically developed for monitoring locations where carbon dioxide concentrations fluctuate significantly, such as chicken coops, greenhouses, and mushroom cultivation rooms. This CO2 sensor accurately measures fluctuations in ambient carbon dioxide levels, and even after prolonged operation in high-concentration environments, it exhibits minimal drift and delivers stable measurement results. For harsh environments, a custom CO2 sensor suitable for high-humidity, high-CO2 environments (such as mushroom cultivation facilities) is available for an additional $10.50.
RS-CO2-*-2FL-EX
This carbon dioxide sensor is mainly used to measure the CO2 concentration in industrial closed pipelines. When in use, you only need to punch holes in the pipe, insert the stainless steel probe of the pipe-type carbon dioxide sensor into the pipe and fix it with a flange. The measuring unit is installed in a stainless steel probe for long-term monitoring of the CO2 concentration in the pipeline. This carbon dioxide sensor can also increase the OLED function, which is convenient for viewing data in real time.
RS-MG41-CO2-5000P-EX
This is a portable CO2 gas detector designed for professionals to conduct multi-point monitoring. It requires no installation or wiring and is easy to carry. This CO2 detector uses natural diffusion to detect gas and features an NDIR infrared sensor, offering excellent sensitivity and outstanding repeatability. It supports manual setting of upper and lower limits, and triggers alarms via sound, vibration, and lights when limits are exceeded. It has a large storage capacity, capable of storing up to 100,000 data points, and can be used with software to view historical data at any time.
RS-FPC-CO2-5000P-*-A-EX

RS-BYH-M-EX
This is a CO2 sensor designed for long-term outdoor monitoring of carbon dioxide concentrations. Placing the CO2 sensor module inside a solar radiation shield not only prevents rainwater from entering and damaging the sensor but also shields it from direct sunlight, which could cause overheating and affect measurement accuracy. This solar radiation shield is also compatible with a temperature and humidity sensor, light sensor, noise sensor, and other devices, and is typically used in conjunction with outdoor weather stations.
Renke RS-CO2*-*-2-*-EX CO2 Sensor
This wall-mounted carbon dioxide sensor is small in size and easy to install, suitable for multi-site installation and centralized monitoring. Users can install multiple co2 sensors in different places and uniformly monitor the working conditions of these devices through our free cloud platform. This co2 sensor can measure only the concentration of carbon dioxide, or the three elements of temperature, humidity and carbon dioxide.

FAQs - CO2 Sensor
What is carbon dioxide?
Carbon dioxide is a kind of carbon-oxygen compound with the chemical formula of CO2. It is a colorless and odorless gas under normal temperature and pressure. It is also a common greenhouse gas and a component of air (0.03%-0.04% of the total volume of the atmosphere).
How to calibrate the CO2 sensor?
Our carbon dioxide sensor has been calibrated before leaving the factory, and there is no need for customers to perform secondary calibration.
How does a carbon dioxide sensor work?
CO2 sensor working principle: The carbon dioxide gas sensor measures gaseous carbon dioxide levels by detecting the quantity of IR radiation absorbed by carbon dioxide molecules.
How to choose a carbon dioxide sensor?
First, choose the best co2 sensor according to the place of use: If the measurement environment is not fixed and the measurement time is short, you can choose a portable co2 detector, which can be carried around and is convenient to use. If the detection environment is fixed and need long-term monitoring, wall-mounted carbon dioxide sensor or home carbon dioxide sensor can be selected, which can be monitored after installation. If you want to monitor the CO2 concentration in a flammable and explosive environment, you can choose an explosion-proof co2 sensor. To measure the concentration of co2 in the pipeline, select a duct mount carbon dioxide sensor. If you have other questions, you can contact us and we have professional and technical personnel to answer you.
What are the applications of carbon dioxide sensors?
- Greenhouse monitoring
The concentration of carbon dioxide required for vegetables is generally 1000～1500ppm. Therefore, the carbon dioxide deficit in the plastic greenhouse has become an important factor affecting the output of vegetables in the plastic greenhouse. The installation of carbon dioxide gas sensors in the plastic greenhouse can ensure timely alarm in the case of insufficient carbon dioxide concentration, to use gas fertilizer ensure high quality and high yield of vegetables, edible fungi, and flowers. - Farming monitoring
Some large farms, such as cattle, pig, chicken factories, etc., are in enclosed or semi-enclosed environments. A large number of livestock will exhale a large amount of carbon dioxide. If ventilation measures are not taken in time, high concentrations of carbon dioxide will cause animal hypoxia, depression, fatigue, anorexia, slow growth, and other problems. At the same time, the lack of air movement can easily lead to a decline in the immunity of livestock and outbreaks of diseases. - Industrial waste gas monitoring
As the economy develops and the level of industrialization increases, human activities (such as burning fossil fuels and deforestation) have exacerbated the increase in greenhouse gas concentrations. There are also some industrial enterprises that use chimneys or exhaust gas in the combustion and production process, and a large amount of CO2 gas is discharged from the opening of the pipe. These make global warming one of the biggest challenges facing mankind today. - Indoor gas detection
The use of carbon dioxide gas sensors can be seen everywhere in our daily life environment, such as kindergartens, schools, office buildings, shopping malls, supermarkets, gas stations, hospitals, and other public places. Monitoring the concentration of carbon dioxide through a carbon dioxide sensor can improve air quality, thereby improving learning and work efficiency.
