High performance, fast response and excellent stability make it an ideal solution for a variety of applications such as greenhouses, cities, poultry farms and transport stations. Seeed Studio 101991029
An advanced digital sensor based on NDIR technology, supporting RS485 (Modbus-RTU/Modbus-ASCII) and SDI-12 communication protocols. It can be used in various environments, and with its wide supply voltage range from 5 to 24V, it is suitable for both indoor and outdoor applications. Equipped with a built-in calibration function, it offers users the ability to easily adjust measurement parameters. The sensor measures three key environmental parameters: carbon dioxide (CO2), air temperature, and relative humidity, providing comprehensive environmental monitoring. With a wide CO2 measurement range (0ppm to 10,000 ppm) and high accuracy (± 50ppm + 3% MV), the device guarantees precise and reliable results. Its high performance, quick response, and excellent stability make it an ideal solution for various applications such as greenhouses, cities, poultry farms, and transport stations.

Additionally, this sensor uses both single air chamber and dual-channel technology, enhancing its accuracy and reliability. The CO2-Connector version is equipped with a waterproof aviation connector, significantly simplifying and speeding up the process of connecting the sensor to a data logger using screws, saving time and effort. Its compact size and ease of installation make it easy to integrate into various applications. Factory calibration and user calibration via buttons or commands further increase user convenience. With the use of PTFE and a protective housing, this sensor boasts better air permeability, resulting in greater measurement accuracy and stability, as well as low power consumption.
