上一篇（https://blog.csdn.net/fm0517/article/details/80967569）通過Python代碼實(shí)現(xiàn)了通過YL-69模塊監(jiān)測土壤濕度。本片實(shí)現(xiàn)通過Django發(fā)布監(jiān)測結(jié)果。

1. 前期準(zhǔn)備

已完成上一篇的內(nèi)容：https://blog.csdn.net/fm0517/article/details/80949387

2. 創(chuàng)建soil應(yīng)用

cd /home/pi/helloworld python manage.py startapp soil

3. 配置Django路徑

cd /home/pi/helloworld/helloworld vi urls.py from django.conf.urls import include, url from django.contrib import admin from helloworld.view import hellourlpatterns = [url(r'^hello/$', hello),url(r'^raspberrypistate/', include('raspberrypistate.urls',namespace="raspberrypistate")),url(r'^temhum/', include('temhum.urls',namespace="temhum")),url(r'^temhum2/', include('temhum2.urls',namespace="temhum2")),url(r'^illuminance/', include('illuminance.urls',namespace="illuminance")),url(r'^soil/', include('soil.urls',namespace="soil")), #添加這一行url(r'^admin/', admin.site.urls), ]

4. 配置soil的urls.py

cd /home/pi/helloworld/soil vi urls.py from django.conf.urls import urlfrom . import viewsurlpatterns = [url(r'^$', views.index, name='index'), ]

5. 配置soil的views.py

cd /home/pi/helloworld/soil vi views.py # -*- coding:utf-8 -*- from django.http import HttpResponse from . import soil# Create your views here. def index(request):sh=soil.getSoilHum()return HttpResponse(sh)

5. 編寫代碼soil.py

cd /home/pi/helloworld/soil vi soil.py #!/usr/bin/python # -*- coding: UTF-8 -*- import RPi.GPIO as GPIO import timedef getSoilHum():channel = 21 #管腳40GPIO.setmode(GPIO.BCM)GPIO.setup(channel, GPIO.IN)if GPIO.input(channel) == GPIO.LOW:return "土壤檢測結(jié)果：潮濕"else:return "土壤檢測結(jié)果：干燥"

6. 重啟服務(wù)，進(jìn)行測試

sudo systemctl restart emperor.uwsgi.service

在樹莓派瀏覽器輸入 http://127.0.0.1/soil
或者在電腦瀏覽器輸入 http://raspberrypi/soil
