```Example 2: IoT Environmental Monitoring using Python and MicropythonThis example demonstrates how to use the ELECROW LR1262 Node Board to send environmental temperature and humidity data to a server using Python and Micropython.```python
import machine
import ubinascii
import urequests
import ujson# Initialize LoRaWan module
lora = machine.LoRa(mode=machine.LoRa.LORAWAN)# Initialize temperature and humidity sensor
temp_hum_sensor = machine.I2C(scl=machine.Pin(5), sda=machine.Pin(4))while True:
# Read temperature and humidity data
temp_data = temp_hum_sensor.read(0x40, 2)
temp = (temp_data[0] << 8) | temp_data[1]
hum_data = temp_hum_sensor.read(0x40, 2)
hum = (hum_data[0] << 8) | hum_data[1]# Create JSON payload
payload = {"temperature": temp, "humidity": hum}
payload_str = ujson.dumps(payload)# Send data to server using LoRaWan
lora.send(payload_str)# Wait for 10 minutes before sending next data packet
machine.sleep(600000)
