A simple Python program for Raspberry Pi that initiates a pump to deliver water from a reservoir when a water sensor reading returns a value indicating that the water level is running low
import RPi.GPIO as GPIO
import time
WATER_SENSOR_PIN = 23
RELAY_CONTROL_PIN = 27
GPIO.setmode(GPIO.BCM)
GPIO.setup(WATER_SENSOR_PIN, GPIO.IN)
GPIO.setup(RELAY_CONTROL_PIN, GPIO.OUT)
