I need help with weatherstation code. I am new to ThingsSpeak. i have set up this code for bme280 to monitor room temprature. I have no idea what configure haeader and connection address is. i have highlited it in the code below please help me .

import time
from w1thermsensor import W1ThermSensor
  
import board
import busio
import adafruit_bme280
i2c = busio.I2C(board.SCL, board.SDA)
bme = adafruit_bme280.Adafruit_BME280_I2C(i2c)
#import adafruit_ads1x15.ads1015 as ADS
#from adafruit_ads1x15.analog_in import AnalogIn
  
import RPi.GPIO as GPIO
import urllib
import http.client
  
key = "*MY KEY"
interval = 5  #How long we want to wait between loops (seconds)
 
while True:
 
    time.sleep(interval)
 
    #Pull Temperature from DS18B20
#    temperature = ds18b20.get_temperature()
 
    #Pull temperature from BME280
    temperature = bme.temperature
 
    #Pull pressure from BME280 Sensor & convert to kPa
    pressure_pa = bme.pressure
    pressure = pressure_pa / 10
 
    #Pull humidity from BME280
    humidity = bme.humidity
 
    #Print the results
   # print( 'Temperature: ' , temperature)
   # print( 'Humidity:    ' , humidity, '%')
   # print( 'Pressure:    ' , pressure, 'kPa')
   # print( ' ')
params = urllib.parse.urlencode({'field1' : temperature, 'field2' : humidity, 'field3' : pressure})
 
        ####Configure header / connection address###
headers = {"Content-typZZe": "application/x-www-form-urlencoded","Accept": "text/plain"}
conn = http.client.HTTPConnection("api.thingspeak.com/update:80")
  
    #Try to connect to ThingSpeak and send Data
try:
        conn.request("POST", "/update", params, headers)
        response = conn.getresponse()
        print( response.status, response.reason)
        data = response.read()
        conn.close()
  
    #Catch the exception if the connection fails
except:
        print( "connection failed")

The headers and connection address seem correct. I might take the ZZ out of "content-type".

You can see more information at the Write Data doc page.

Are you getting a success code for the response?

I don't think its a ThingSpeak issue. You have several print statments before the ThingSpeak post that aren't hapeining. I'd take everything out of the code and add stuff back in one at a time to see if you can see what is breaking it.
