以下是可以生成的Python代码:
```
import minimalmodbus
import time
# Set up connection to the sensor
instrument = minimalmodbus.Instrument('/dev/ttyUSB0', 1)
instrument.serial.baudrate = 9600
instrument.serial.bytesize = 8
instrument.serial.parity = minimalmodbus.serial.PARITY_NONE
instrument.serial.stopbits = 1
instrument.serial.timeout = 0.1
while True:
try:
# Read temperature and humidity values from sensor
temperature = instrument.read_register(0, functioncode=4)
humidity = instrument.read_register(1, functioncode=4)
print(f'Temperature: {temperature} °C, Humidity: {humidity}%')
time.sleep(5) # Wait for 5 seconds before taking the next reading
except Exception as e:
print(f'Error reading sensor data: {e}')
break
```
这就是一个基本的Python代码,用于读取树莓派CM4 Sensing连接的RS485类型的温湿度传感器的数据。你可以通过修改串口设备的名称和传感器的地址来适应你的具体情况。希望这对你有所帮助!
