I have this modified code how can i add the following,

I want every time i bring an object closer, it triggers the change in temperature and the buzzer buzzes once with a different tone for the diffferent centimeters

the buzzer should not be continous just one buzz and it sleeps and when the temperature and humidity change as i bring the object closer it buzzes.

could anyone help.

ultrasonic ranger distance buzzer value

>20 cm 0

<20cm 15

<15cm 25

<10 cm 50
