Range hood detection control circuit
Shown is a range hood detection and control circuit . The main component in this circuit is the gas sensor MQ-211. When the gas
sensor detects oil fume gas. A DC voltage will be generated at point B. This voltage is added to the @ pin of Icl, causing the IC1 ③ and ⑦ pins to output control signals . The drive signal
of the @ pin causes the relay K to act and drives the motor to pump air. The signal of the ⑦ pin causes the oscillation When the alarm is activated, the buzzer will
sound and the LED will light up to indicate.
