MicroPython offers rich library support to IoT developers, simplifying interactions with hardware. Especially noteworthy are the machine and network libraries, which provide essential tools for controlling hardware interfaces (such as GPIO, ADC, UART) and network communication (such as TCP/IP protocols). The following table lists some of the key modules and functions from these libraries:
| Library Name | Module/Function | Description |
|---|---|---|
| machine | Pin | Controls individual IO pins (digital read/write, PWM signals, etc.). |
| machine | ADC | Reads analog signals. |
| machine | UART | Facilitates data communication through serial ports. |
| network | WLAN | Manages wireless LAN interfaces, supports operations like connecting/disconnecting to WiFi networks. |

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 = temp_sensor.read() # Read temperature value
if temp > 30:
water_pump.value(1) # Temperature too high, turn on water pump
else:
water_pump.value(0) # Temperature appropriate, turn off water pump
sleep(600) # Check every 10 minutesThis 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.
