How to choose the right sensor in Winsen?
The Winsen manufacturer has decades of experience in the field of CO2 sensors. Winsen can provide various CO2 sensors or related solutions. Choosing the right CO2 sensor can save your time and improve your work efficiency.
First, determine your field. For example, the choice of CO2 sensors in civil, agricultural, and industrial fields is different. Click here to learn about the selection of CO2 sensors in different fields.
Second, determine the required accuracy, which is often inseparable from the number of channels. The dual channel CO2 sensor performed even better.
Third, determine the range. Since CO2 gas exists in the atmosphere, the starting point of most ranges is 400ppm, except for agriculture.
Fourth, other parameters. Such as response time, installation method, price, etc.
CO2 sensor application scenarios
CO2 sensors can play their role in all walks of life. Through more than 20 years of continuous accumulation and cooperation with customers in different industries, Winsen can help you meet the needs of different scenarios.

How Winsen guarantees the quality of CO2 sensors
Winsen has more than 100 R&D personnel and more than 500 sets of production and R&D equipment. Many R&D achievements have passed the appraisal of scientific and technological achievements in Henan Province and reached the international advanced level. At present, Winsen has more than 100 invention and utility model patents, more than 10 software copyrights, and has led or participated in the formulation of 14 national and industry standards.
Winsen CO2 sensor has a wide measurement range, wide detection range, simple application, not easy to be poisoned, and has a lot of options.
In addition, the Winsen CO2 sensor will be aged, calibrated, tested and packaged before delivery from the factory, and then transferred to the warehouse for delivery. If the sensors are placed in the warehouse for more than 7 days, we will calibrate and test them again to ensure the quality of the product. When calibrating, we will first calibrate the temperature (8 temperature points), and then calibrate the gas (zero point and SPAN point), and the SPAN point is determined by the customer's demand range.
We can provide you with professional advice in different industries.

CO2 Sensor Guide
We have summarized the following questions to help you make better choices.
What is a CO2 sensor?
The CO2 sensor is a device that converts the collected information (CO2 concentration) into signals (such as electrical signals, acoustic signals, light signals, digital signals, etc.) that are more easily recognized by humans.
What are the range of infrared CO2 sensor?
The range of infrared CO2 sensor is 0-2000ppm, 0-5000ppm, 0-1%VOL, 0-3%VOL, 0-5%VOL, 0-10%VOL, 0-15%VOL. Different models of sensors have different ranges, you can choose the appropriate model according to the actual use environment, or contact us for help.
What should be paid attention to when CO2 sensors are used in agricultural greenhouses?
Agricultural greenhouses are a special application scenario. The respiration of plants is to absorb CO2 by exhaling oxygen, so the CO2 concentration may be lower than 400ppm. At this time, the co2 sensor needs to turn off the automatic calibration function.
What calibration methods are available for CO2 sensors?
For the convenience of customers, the CO2 sensor has three calibration methods to choose from: manual zero calibration, automatic zero calibration and command zero calibration. The zero point calibration function refers to the calibration of 400ppm.
1. Manual zero calibration. Manual zero calibration is to input the HD pin of the sensor to a low level (0V) for zero calibration, and the low level needs to last for more than 7 seconds. Before zero calibration, it is necessary to ensure that the sensor operates stably for more than 30 minutes at a concentration of 400ppm.
2. Automatic zero calibration. The automatic zero-point calibration function means that after the sensor runs continuously for a period of time, it intelligently judges the zero point according to the environmental concentration and calibrates itself. The calibration cycle is an automatic calibration every 24 hours since the power-on operation. The zero point for automatic
calibration is 400ppm. The automatic zero calibration function is suitable for office environment and home environment. However, it is not suitable for agricultural greenhouses, farms, cold storages and other places. In such places, the automatic zero calibration function should be turned off. After closing, the user should periodically calibrate the sensor zero point.
3. Command zero calibration. Sending calibration commands to the sensor through the serial port (URAT) can realize sensor zero calibration. For the zero point calibration command, please refer to the product manual.
Precautions for using CO2 sensor
● During the welding, installation and use of CO2 sensor, the plastic gold-plated cavity should be prevented from being subjected to pressure in any direction.
● If CO2 sensor needs to be placed in a small space, the space should be well ventilated, especially the diffuser window should be in a well ventilated location.
● In order to ensure that the CO2 sensor can work normally, the power supply voltage must be kept in the range of (5.0±0.1) V DC, and the power supply current must not be less ● than 150mA. If it is not within this range, the sensor may malfunction, the output concentration of the sensor is too low, or the sensor cannot work normally.
● CO2 sensor should be kept away from heat sources and protected from direct sunlight or other thermal radiation.
● CO2 sensor should be calibrated regularly, and the calibration period is recommended not to exceed 6 months.
● Do not use CO2 sensor for a long time in an environment with high dust density.
● When manually calibrating the zero point or sending a command to calibrate the zero point, it must work continuously for more than 30 minutes in a stable gas environment (400ppm).
● CO2 sensor is prohibited from using wave soldering.
● When soldering with a soldering iron, the temperature must be set at (350±5) °C, and the soldering time must be less than 3 seconds.
