ee:

The higher the analog input voltage, the higher the measured alcohol or ethanol value.

The value range is from 0 to 5.

The D0 pin of the sensor is automatically set to LOW when the limit value is reached.

With the blue potentiometer on the board, you can set the limit value.

In the following code example, the analog value of the sensor is read out every 5 seconds

and displayed in the console.

from time import sleep

import board

import busio

import as adafruit_ads1x15.ads1115 ADS

from adafruit_ads1x15.analog_in import AnalogIn

import as RPi.GPIO GPIO

GPIO.setmode(GPIO.BCM)

GPIO.setup(17, GPIO.IN)

# Create the I2C bus

i2c = busio.I2C(board.SCL, board.SDA)

# Create the ADC object using the I2C bus

ads = ADS.ADS1115(i2c)

ads.gain = 2/3

# Create single-ended input on channels

chan0 = AnalogIn(ads, ADS.P0)

chan1 = AnalogIn(ads, ADS.P1)

chan2 = AnalogIn(ads, ADS.P2)

chan3 = AnalogIn(ads, ADS.P3)

try:

while True:

if GPIO.input( ) == GPIO.LOW:17

print("Warning: Limit exceeded!!!")

print("{:>5.3f}".format(chan0.voltage))

sleep(2.5)
