Hi Daniel,
I don't have two ds18b20 sensors to test this Python script against, but you will need to do something like the script attached (untested, could be cleaned up). This script hardcodes the two ds18b20 serial numbers and adds a parameter to the two functions to choose which sensor to read. The streamer.log statements send data from the different sensors to different data streams. Let me know if this helps at least push you in the right direction.
import os
import glob
import time
from ISStreamer.Streamer import Streamer
streamer = Streamer(bucket_name="Temperature Stream", bucket_key="piot_temp_stream031815", access_key="PUT_YOUR_ACCESS_KEY_HERE")
os.system('modprobe w1-gpio')
os.system('modprobe w1-therm')
# Serial numbers are hard-coded
base_dir = '/sys/bus/w1/devices/'
device_folder1 = glob.glob(base_dir + '28-0120191bb3f3')[0]
device_file1 = device_folder1 + '/w1_slave'
device_folder2 = glob.glob(base_dir + '28-0120191cfc09')[0]
device_file2 = device_folder2 + '/w1_slave'
def read_temp_raw(device_num):
if device_num == 1:
f = open(device_file1, 'r')
else
f = open(device_file2, 'r')
lines = f.read
f.close()

Hi Elizabeth,
I am using your code above to monitor temperatures and the program works perfectly! I am so new at working with python and raspberry pi and your article was informative and easy to follow.
When I run the temperature.py program, my initial state data bucket (I named it "Temperature Stream") displays two graphs Celsius and Fahrenheit.
I would like to monitor multiple sensors. I am starting with two. I am using the DSB18B20 solution and I have added one additional sensor that shows up in the /sys/bus/w1/devices/ folder. (now two sub folders appear with names starting with "28"-".
how can I modify the temperature.py code to see both sensors or if that is not the way to do it, do I do something in my initialstate data bucket? I know it is probably a no-no, but I have displayed the temperature.py code with my initialstate access_key below.
import os
import glob
import time
from ISStreamer.Streamer import Streamer
streamer = Streamer(bucket_name="Temperature Stream", bucket_key="piot_temp_stream031815", access_key=ist_ORc4ZZ_nl0M5bolOx-fdO80GNoKNSRuC)
os.system('modprobe w1-gpio')
os.system('modprobe w1-therm')
base_dir = '/sys/bus/w1/devices/'
device_folder = glob.glob(base_dir + '28*')[0]
device_file = device_folder + '/w1_slave'
def read_temp_raw():
f = open(device_file, 'r')
lines = f.readlines()
f.close()
return lines
def read_temp():
lines = read_temp_raw()
while lines[0].strip()[-3:] != 'YES':
time.sleep(0.2)
lines = read_temp_raw()
equals_pos = lines[1].find('t=')
if equals_pos != -1:
temp_string = lines[1][equals_pos+2:]
temp_c = float(temp_string) / 1000.0
return temp_c
while True:
temp_c = read_temp()
temp_f = temp_c * 9.0 / 5.0 + 32.0
streamer.log("temperature (C)", temp_c)
streamer.log("temperature (F)", temp_f)
time.sleep(.5)
I appreciate any help.

Hi Elizabeth,
I cannot tell you how much I really appreciate this. You’ve gone above and
beyond.
I will work on this later this week. I am such a new programmer,
(56-year-old “recovering attorney“ self tight). I’m not sure if you would
like to see any successful code down the line. If you would, I will send it
to you and see what you think.
Again, you’ve gone above and beyond and I cannot express my gratitude
enough.
Daniel

Hi Daniel,
It’s never too late to start! Let me know once you have this working, I’d love to see any temperature dashboards you create. Feel free to reach out with any questions. As someone who only got really into Python about two years ago, I understand.
Thanks,

Hi, im totally lost in the code. I have the exact same request. I have one sensor , works great. I want to add another sensor. I tried to follow that code and add your things,..but I get lost in it. Can you give me a different pasted code I can just cut and paste and then enter my serial numbers manually.. ? Thanks tom.
Hi,
I don’t have any example code for multiple sensors. It would require some tinkering to make it work with multiple sensors and we just haven’t done that yet.

Hi,
I may have misunderstood. Are you saying the code as is does not work?
Thanks,

Hi Elizabeth,
I am using your code above to monitor temperatures and the program works perfectly! I am so new at working with python and raspberry pi and your article was informative and easy to follow.
When I run the temperature.py program, my initial state data bucket (I named it "Temperature Stream") displays two graphs Celsius and Fahrenheit.
I would like to monitor multiple sensors. I am starting with two. I am using the DSB18B20 solution and I have added one additional sensor that shows up in the /sys/bus/w1/devices/ folder. (now two sub folders appear with names starting with "28"-".
how can I modify the temperature.py code to see both sensors or if that is not the way to do it, do I do something in my initialstate data bucket? I know it is probably a no-no, but I have displayed the temperature.py code with my initialstate access_key below.
import os
import glob
import time
from ISStreamer.Streamer import Streamer
streamer = Streamer(bucket_name="Temperature Stream", bucket_key="piot_temp_stream031815", access_key=ist_ORc4ZZ_nl0M5bolOx-fdO80GNoKNSRuC)
os.system('modprobe w1-gpio')
os.system('modprobe w1-therm')
base_dir = '/sys/bus/w1/devices/'
device_folder = glob.glob(base_dir + '28*')[0]
device_file = device_folder + '/w1_slave'
def read_temp_raw():
f = open(device_file, 'r')
lines = f.readlines()
f.close()
return lines
def read_temp():
lines = read_temp_raw()
while lines[0].strip()[-3:] != 'YES':
time.sleep(0.2)
lines = read_temp_raw()
equals_pos = lines[1].find('t=')
if equals_pos != -1:
temp_string = lines[1][equals_pos+2:]
temp_c = float(temp_string) / 1000.0
return temp_c
while True:
temp_c = read_temp()
temp_f = temp_c * 9.0 / 5.0 + 32.0
streamer.log("temperature (C)", temp_c)
streamer.log("temperature (F)", temp_f)
time.sleep(.5)
I appreciate any help.
