Understanding a Gas Sensor | Jaycon Systems

· This resistor serves to adjust the sensor’s sensitivity and accuracy. The value can range anywhere from 2k Ohms to 47k Ohms. The higher the value, the more sensitive the sensor becomes. The value depends on whether you want to measure high concentrations of gas or not. If you choose to measure high concentrations of gas, but choose a high value for the load resistor, then the readings …
