Code for detecor without microcontroller

Approach 1 (Environmental Safety Application Theme) You have been hired by a company that manufactures environmental safety equipment for different indoor facilities. The company is in a process to design a complete system for measuring the levels of Carbon Monoxide. You are assigned the task of designing a circuit that measures the Carbon Monoxide levels and produces an alert if the level is more than a certain safe value. The developed prototype should have the following parts: The required sensor that needs to be used in this application. b. The maximum Carbon Monoxide value at which the system will produces an alert should be controllable. You should indicate that the Carbon Monoxide is normal or up-normal using LED. d. An output sound should be produced by the circuit in case of up-normal level. C
