Were you able to find any flaws in the previous code? They are not hard to find; the code works brilliantly when it's only a single person in the room. If this is installed somewhere where multiple people are coming and going, then it might be challenging. This is because whenever a person moves outside, the light will be turned off.

So now that the problem is evident, it's time to make the code even more better. To do this, the hardware will remain exactly the same; we simply need to make the code smarter. Let's see how we can do that:

import GPIO library
   import RPi.GPIO as GPIO
   import time
   import time
   import Adafruit_ADS1x15
   adc0 = Adafruit_ADS1x15.ADS1115()
GAIN = 1
 adc0.start_adc(0, gain=GAIN)
adc1.start_adc(1, gain=GAIN)
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
PCount = 0
while True:
   F_value = adc0.get_last_result()
   F1 = (1.0 / (F_value / 13.15)) - 0.35
   time.sleep(0.1)
   F_value = adc0.get_last_result()
   F2 = (1.0 / (F_value / 13.15...
