The 4PID-SMART-CO1 Module is the gas detector based on the principle of photoionization detection (Photo-Ionization Detector, PID). This is a widely used and highly sensitive sensor module for the concentration of VOCs present in the environment. The module uses SemeaTech 4PID sensors as the sensitive component (specific technical parameters of the sensor refer to the datasheet) and performs gas concentration detection through signal sampling, amplification, filtering and conversion. It features built-in temperature compensation, linear correction and other functions, ensuring excellent stability and selectivity.
The 4PID-SMART-C01 Module supports UART signal output modes, allowing direct output of digital and analog voltage signals that represent gas concentration data, which is easy to operate.
