Here is how the circuit is hooked up. Once the data is in a channel, you can easily visualize and analyze the data with MATLAB code. Also note that the minimum delay required between two readings from DHT11 sensor is 2 seconds, so always use delay greater than 2 seconds. This time postponement with URL to send the data from python IDLE. Just wondering if you know how I could extract the data to tweet it please. There are a couple of limitations that seem minor, basically each channel supports up to 8 fields and you can only send data every 15 seconds. We use a the Dexter Industries Thermometer to measure the temperature in the room and then post the data up on the ThingSpeak website. The board is connected to a DHT11 sensor that measures temperature and humidity and an analog light sensor that measures the light intensity. The core element of ThingSpeak is a ‘ThingSpeak Channel’. No data is sent to any server. How do I format data to send data using udp. Create a table called Movies and load sample data in JSON format. If it's low you get a '0'. If you have more than one sensor value that you want to send to ThingSpeak, you can choose to publish multiple values to a channel feed. At the moment I am still new, so I am using a thingspeak. To upload our data, we need an API key, which we will later include in a piece of python code to upload our sensor data to Thingspeak Website. For example, an XML file like this:. the following is the said temperature sensor data from the office, streamed to thingspeak using ESP8266 and Arduino Mega since 31dec14.
