makes a circuit which has transistors, diodes, relays, IC Timer, LED, which first turns on a green LED lit from 0 to 35 degrees Celsius then turns off and turns on a yellow LED from 35 degrees Celsius to 50 degrees Celsius then turns off the yellow and turns on the red at 50 degrees or more which in turn will turn on an oscillator circuit with IC555 and a Buzzer. In addition it should turn on an exhaust fan at 110 VAC. Translated with DeepL.com (free version)
