The higher the analog input voltage, the higher the hydrogen gas 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
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)
except :KeyboardInterrupt
GPIO.cleanup()
