Problems solved by technology

[0002] Many industrial waste gases are highly dangerous. During the treatment process, the concentration of the waste gas needs to be monitored at all times. The general gas concentration detection system includes sensors, signal conditioning circuits, switch control circuits, analog / digital conversion circuits and digital display circuits. Between the switch control circuit and the analog / digital conversion circuit, we need to set up a gas detector to remind the staff on site, compare the detected signal voltage with the voltage set by the factory itself, and give an alarm according to the situation after the result is obtained. At present, the simple gas detector used for waste gas treatment has a relatively complicated structure, high cost of use, and poor detection effect, which brings certain dangers to the staff.
