Gas Sensor Applications |

A sensor that is ideal for measuring indoor CO2 levels for indoor air quality will not work to measure concentrations used in fire suppression testing. One OEM might want I2C protocols, while another individual prefers UART. Some applications require the use of a sampling sensor instead of diffusion. Furthermore, understanding your application and its requirements is vital in selecting the ...
