Renke CO2 Sensor Types


RS-CO2*-*-2 carbon dioxide sensor with rs485, 4-20ma, 0-5v, 0-10v output. A temperature and humidity probe can be added to the bottom of the transmitter to be used as a co2 temperature and humidity sensor while measuring the concentration of co2 gas and the temperature and humidity value of the current environment. This is a wall mounted co2 sensor that can be used in greenhouses, industrial production, and buildings. If you need to view the value on the devices, you can add $10.5 to add OLED display function.

co2 sensor
industrial co2 sensor


This CO2 sensor was developed to monitor places where the CO2 concentration varies greatly, such as chicken coops. It can accurately measure the value of CO2 concentration in the environment with large changes. Working in places with high CO2 concentration for a long time, the drift is small and the measurement is stable. This CO2 sensor has built-in temperature compensation and is less affected by temperature. On the basis of this carbon dioxide sensor, add $10.5 to customize a carbon dioxide sensor that can be used in environments with high humidity and high carbon dioxide concentration such as mushroom sheds.


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.

duct co2 sensor
portable co2 sensor


This is a portable CO2 gas detector, which can measure the CO2 concentration in the current environment within a few seconds after turning on the device. No installation and wiring is required. Take it with you anywhere. The carbon dioxide gas in the environment is detected by the detection unit through natural diffusion. The upper and lower limits of the measured value can be freely set through the buttons on the device. Once the limit is exceeded, it will alarm through vibration, sound and light. Built-in storage function, continuous monitoring can store 100,000 pieces of data.


This fixed carbon dioxide gas detector can be used in flammable and explosive industrial places. Its overall appearance is made of stainless steel, which has good waterproof and dustproof effects. With large LCD display and sound and light alarm function. This carbon dioxide detector can modify parameters through remote infrared remote control technology without disassembly. It can be used in harsh environments such as industrial production for a long time. It can also be used to measure carbon dioxide gas in tubes.

fixed co2 sensor
outdoor CO2 sensor


This carbon dioxide sensor is a device that has been used for outdoor environmental monitoring for a long time. The carbon dioxide sensor module is placed in an anti-radiation shield, which not only prevents rainwater from entering and damaging the sensor, but also prevents direct sunlight from causing excessive temperature to affect the value. The solar radiation shield can also be compatible with temperature and humidity sensors, light sensors, noise sensors, etc. Usually used with an outdoor weather station.

CO2 Sensor Applications

01 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.

02 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.

03 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.

04 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.


More information about 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 carbon dioxide 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.
