Uploading data from RPi SenseHat to Thingspeak via python script | Raspberry Pi | Forum

Dear fellow coders, i'm trying to upload temperature data from my RPi sensehat -> Thingspeak channel. I copied the scripts from the internet and tried to integrate them together. I executed the Python script on Putty terminal, the printed temperature looks ok, hovering between 29-30 degrees C but when displayed on thingspeak, it shows up as werid numbers like 4 or 6 degrees C.

Greatly appreciate your advice! Thank you!

import httplib, urllib

sleep = 3

key = '...'

def thermometer():

from sense_hat import SenseHat

sense = SenseHat()

sense.clear()

tmax = 40

tmin = tmax - 8

while True:

temp = sense.get_temperature()

#-----rd off temp to 2 d.p.-----

temp = round(temp,2)

print(temp)

temp = int(temp) - tmin

for x in range(0, 8):

for y in range(0, temp):

sense.set_pixel(x, y, 255, 0, 0)

for y in range(temp, 8):

sense.set_pixel(x, y, 0, 0, 0)

params = urllib.urlencode({'field1': temp, 'key':key })

headers = {"Content-typZZe": "application/x-www-form-urlencoded","Accept": "text/plain"}

conn = httplib.HTTPConnection("api.thingspeak.com:80")

try:

conn.request("POST", "/update", params, headers)

response = conn.getresponse()

print temp

print response.status, response.reason

data = response.read()

conn.close()
