DAQ - GP- CO24G wireless infrared carbon dioxide CO2 sensor terminal is a wireless carbon dioxide concentration measurement product launched by Shanghai Shucai IoT Technology Co., Ltd. The principle is to use the non-dispersive infrared (NDIR) principle to detect CO2 in the air. Since different types of gases absorb infrared light of specific wavelengths, the relationship between gas concentration and absorption intensity (Lambert-Beer law) is used to identify gas components and determine their concentrations . Compared with chemical sensors , it is not easily affected by environmental interference.
This device is mainly composed of an optical sensor consisting of an infrared light source, an optical path, an infrared detector, and a software algorithm , and its supporting wireless transmission protocol processing part. This product can be widely used in carbon dioxide concentration monitoring in gas pipelines, smart agricultural breeding, chemical plants, production workshops and other fields.
The sensor terminal supports 4G /WiFi/LoRa and other communication methods by default , as well as MQTT, HTTP and other communication methods. It can overcome the wireless communication obstruction caused by the special environment on site, greatly simplifying the on-site deployment time and reducing construction costs .
