Examples

Raspberry Pi Pico - Micropython

from machine import ADC, Pin
import time

a0 = ADC(Pin(27))  # Create an ADC object on pin 26 (ADC0)
d0 = Pin(22, Pin.IN, Pin.PULL_UP)  # Digital output from sensor

while True:
    reading = a0.read_u16()  # Read the value from the analog interface
    print("Sensor reading:", reading)
    
    threshold_exceeded = d0.value()  # Read the value from the digital interface
    if threshold_exceeded:
        print("Threshold exceeded!")
    
    time.sleep_ms(500)  # Wait for half a second before reading again
