Choose the _Line Chart_ and on the next screen check the **Temperature** feed. Click the **Next Step** button, accept the default options and click **Done**. You will see the graph displayed on your dashboard. - -## Subscribing to a Topic - -So far you have been viewing data that has been published by the NodeMCU. In this section you will be publishing from the io.adafruit web page and your NodeMCU will subscribe to these messages! - -If you examine the sample code you will see that there is already code that subscribes to the `/feeds/onoff` topic. Make sure you are on your **Environment** dashboard and use the blue `+` to button to create a new block. This time choose a **Toggle** and, in the popup window enter `onoff` in the box labelled _Enter new feed name_ and click on the blue **Create** button. - -Make sure the Arduino _Serial Monitor_ is open and displaying the sensor values. Slide the on/off switch to the on position, what is displayed in the serial monitor? Slide it back to _off_, what is displayed? Can you find the code in the sketch that is being triggered? - -## Battery Power - -You have probably noticed that as soon as you disconnect the USB cable the NodeMCU stop running. This is solely because you have removed the power being supplied through the USB cable. It is useful to do this during development however rather inconvenient to have to permanently attach it to your computer. There are two ways you can power the NodeMCU after you disconnect from the computer: - -1. Plug the NodeMCU into a USB power bank. -2. Use a breadboard power supply to provide 3.3v to the VIN pin. - -The best solution is to simply power the NodeMCU either using a microUSB power supply (wall wart) or using a phone power bank. - -### Using the Breadboard Power Supply - -Your IoT kit comes with a breadboard power supply that can supply either 3.3v or 5v to both power rails on the breadboard. - -**Make sure you set the two jumpers to supply 3.3v!** - -![DHT11 Breadboard Wiring](../../.images/DHT11_w_PSU.png) - -As you can see, the power is taken off the lower rail and supplied to the VIN pin, this powers the NodeMCU. This same rail also supplies the DHT11 sensor. - -Disconnect the USB cable and supply power to the power supply unit. This can be: - -1. A 9v battery (using the supplied battery clip). -2. 4x AA batteries (using the battery box in the kit). -3. A 'wall wart' mains power supply (between 5 and 9v). -4. Usb power by connecting using the USB connector. - -You can power the system on and off using the white power button. - -### Reducing Power Drain - -At the moment your NodeMCU is drawing full power all the time. To conserve power (and allow you to run for longer on a battery) there are a number of steps you can take. - -The first is to reduce the sensor sample rate, taking a reading consumes power. - -The second approach is to put the NodeMCU into **deep sleep** until we need to take another sensor reading. To do this you need to connect the - -Pulling the **RESET** button _LOW_ resets the microcontroller (the equivalent of switching it off and on again). There is also a `RST` button next to the USB connector which does this for you. The ESP8266 microcontroller can be put into a deep sleep mode for a predetermined time (measured in microseconds). During this time only the Real-Time Clock (RTC) is running as this is needed to work out when to end the deep sleep. Once the time is up the `WAKE` pin is pulled low. - -On the ESP8266 `D0` is the `wake` pin and `rst` is the reset pin. - -What this means in practice is that we need to wire these pins together so that when the timer is done, the WAKE pin goes low and restarts the MCU. However this means we have to make a critical change to our code! Since the MCU is reset, the setup() function is run each time and so we need to move the code from loop() to setup(), see the example below: - -```cpp -void setup() { - Serial.begin(9600); - Serial.setTimeout(2000); - while(!Serial) {} // wait for the serial connection... - Serial.println("I'm awake."); - Serial.println("Going into deep sleep for 20 seconds"); - ESP.deepSleep(20e6); -} - -void loop() {} -``` - -The parameter sent to `ESP.deepSleep()` is the number of microseconds to wait until pulling the `WAKE` pin low (restarting the MCU). `20e6` is scientific notation for 20 x 10 to the power of 6, 20,000,000 microseconds or 20 seconds. - -## Tracking Your Data - -Set up your remote sensor module somewhere safe and install the [DataFeeds app](https://itunes.apple.com/us/app/datafeeds-a-feed-monitor-for-adafruit-io/id1163614771?mt=8).
