1. 掛載DS18B20
sudo modprobe w1-gpio
sudo modprobe w1-therm
2. 安裝Python的庫單總線溫度計訪問庫: w1thermsensor
pip install w1thermsensor
3. 新建一個iot.py文件敲入以下代碼
#!/usr/bin/env python
#coding=utf8
import httplib, urllib
from w1thermsensor import W1ThermSensor
import time
import socket, serial, time
import httplib
import json
HOST = "open.lewei50.com"
PORT = 80
user_key = '樂為物聯(lián)的userkey'
def send_data_to_yeelink(temp):
httpClient = None
try:
params = json.dumps({'value': temp})
headers = {"Content-type": "application/json"
, "Accept": "text/plain",'U-ApiKey': 'Yeelink的api key'}
print params
httpClient = httplib.HTTPConnection('api.yeelink.net', 80, timeout=30)
httpClient.request("POST", "/v1.1/device/設備id/sensor/傳感器id/datapoints", params, headers)
response = httpClient.getresponse()
print response.status
print response.reason
print response.read()
print response.getheaders() #獲取頭信息
except Exception, e:
print e
finally:
if httpClient:
httpClient.close()
def send_data(temp):
httpClient = None
try:
params = json.dumps([{'Name': '傳感器名稱', 'Value': temp}])
headers = {"Content-type": "application/x-www-form-urlencoded"
, "Accept": "text/plain","userkey":user_key}
print params
httpClient = httplib.HTTPConnection(HOST, 80, timeout=30)
httpClient.request("POST", "/api/V1/Gateway/UpdateSensors/01", params, headers)
response = httpClient.getresponse()
print response.status
print response.reason
print response.read()
print response.getheaders() #獲取頭信息
except Exception, e:
print e
finally:
if httpClient:
httpClient.close()
while True:
for sensor in W1ThermSensor.get_available_sensors([W1ThermSensor.THERM_SENSOR_DS18B20]):
temp=sensor.get_temperature()
print("Sensor %s has temperature %.2f" % (sensor.id,temp ))
send_data(temp)
send_data_to_yeelink(temp)
time.sleep(120)
4. 運行python腳本
python iot.py
5. 如果溫度讀取成功且上傳成功會打印相關消息.
