Module control system for handheld carbon monoxide detector

The invention discloses a module control system for a handheld carbon monoxide detector. The module control system comprises a control system body. The control system body is turned on or off through a key module control system connected with the control system body. Information collected by the control system body is transmitted to a liquid crystal screen display module connected with the control system body for displaying and reading. The control system body is powered by a power module. When the content of carbon monoxide needs to be detected, a suction type gas sampling module begins to work, a carbon monoxide sensor module and a temperature and humidity sensor module in the suction type gas sampling module transmit information collected from a sample to be detected to the control system body and display the information through the liquid crystal screen display module connected with the control system body, sound and light prompts are sent out for a detection result through a sound and light prompting module connected with the control system body, and the suction type gas sampling module is controlled by a motor control module connected with the control system body. The module control system has the advantages of being convenient to operate and real and reliable in detection data.
