Case Study: Smart Greenhouse Environment Control

To further demonstrate MicroPython's practical application in IoT development, consider a smart greenhouse environment control system. In this system, MicroPython is used to collect temperature and humidity data, control irrigation systems, and adjust greenhouse temperature conditions:

from machine import Pin, ADC
from time import sleep

# Initialize sensors and controllers
temp_sensor = ADC(Pin(34))
water_pump = Pin(12, Pin.OUT)

# Control logic
while True:
    temp =  # Read temperature value
    if temp > 30:
        water_pump.value(1)  # Temperature too high, turn on water pump
        water_pump.value(0)  # Temperature appropriate, turn off water pump
    sleep(600)  # Check every 10 minutes

This example illustrates how MicroPython's machine library can be used to implement simple control logic for physical devices. In this way, MicroPython makes device development not only efficient but also economical.
