Arduino has published a tutorial for their WiFi 101 Shield that sends data to ThingSpeak. The Arduino WiFi Shield 101 is a powerful Internet of Things shield with crypto-authentication that connects your Arduino or Genuino board to the internet using WiFi.
You only need a few things to build a light and temperature sensor that writes data to ThingSpeak:
- Arduino Zero or Uno Board
- Arduino Wifi Sheild 101
- Temperature Sensor (This example uses a TMP36)
- 10K Ohm Resistor
Once you have the circuit built, you create a ThingSpeak channel, connect the Arduino WiFi 1010 to your Wi-Fi network, and install the source code from the tutorial on the Arduino.
Data is now being sent to your ThingSpeak Channel. Go to your channel to see two charts of the light and temperature data. To take the project a step further, go to ThingSpeak Apps and use MATLAB to analyze and visualize and trigger actions from the data.
