SW205 is a gas detection module based on the NDIR infrared absorption principle. Suitable for detecting carbon dioxide concentration in aqueous solutions. SW205 adopts a patented design (ZL 2014 2 0356666.6) optical cavity,imported light source and dual-channel detector to achieve dual optical path reference compensation in space. CO commonly used in aquaculture2Measurement,sewage measurement and other liquid environments.
The air inlet method of this module is diffusion type; the typical measurement range in water is 0-2000Ppm,other ranges can be customized; the resolution is 4ppm~8ppm; it has UART output,IIC output,and analog voltage output. Powered by 5V. Measuring range and temperature compensation range can be customized.
