5. Configure your board to send data to the cloud service at regular intervals.

Here’s a basic Python script for reading data from a DHT11 sensor connected to a Raspberry Pi:

import Adafruit_DHT
import time
import requests

sensor = Adafruit_DHT.DHT11
pin = 4
api_key = "YOUR_THINGSPEAK_API_KEY"

while True:
    humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)
    if humidity is not None and temperature is not None:
        print(f"Temp={temperature:.1f}°C  Humidity={humidity:.1f}%")
        
        # Send data to ThingSpeak
        requests.get(f"https://api.thingspeak.com/update?api_key={api_key}&field1={temperature}&field2={humidity}")
    else:
        print("Failed to retrieve data from the sensor")
    
    time.sleep(60)  # Wait for 60 seconds before the next reading
