Netduino Home Automation Projects
Most helpful customer reviews on Amazon. February 2, - Published on Amazon. Verified Purchase. What code is provided in the book is full of typos and incomplete with no explanation regarding the missing declarations and types. To get the code you have to let the publisher spam you. Just not worth the headache.
Frankly I would advise looking for alternatives to this publisher for any subject due to their 'we won't give you code without you setting yourself up for spam from us and whoever we sell you to'. November 3, - Published on Amazon. Even after connecting GPS antenna reception indoor does not work Also the web site structure to set and get going is confusing Will add more points after testing other board features October 30, - Published on Amazon.
This book is aimed at the new user, and goes as far as being careful to explain the source code in detail.
The first sample was a good introduction, but further samples required additional hardware that, I felt, weren't adequately explained. What is a TIP , and what does it do? The Grove-Relay module is a digital normally-open switch. An LDR is a component that has a variable resistance that changes with the light intensity that falls upon it.
This allows them to be used in light sensing circuits.
Typically, the resistance of the LDR or Photo-resistor will decrease when the ambient light intensity increases. This is a multi-functional sensor that gives you temperature and relative humidity information at the same time. It utilizes a TH02 sensor that can meet measurement needs of general purposes.
This sensor is designed for comprehensive monitor over indoor air condition. It's responsive to a wide scope of harmful gases, as carbon monoxide, alcohol, acetone, thinner, formaldehyde and so on. Due to the measuring mechanism, this sensor can't output specific data to describe target gases' concentrations quantitatively. But it's still competent enough to check whether indoor air quality is good or not.
For using this software you have to put the Netduino board into DFU mode. To put Netduino in DFU mode you need to press switch available on board then plug USB power cable keeping button pressed and after this release. Before updating the Wi-Fi setting you can use the same software to update the firmware inside your Netduino board.

Then proceed with adding WiFi setting according to your router. Visit Following link for more information on updating the Wi-Fi Setting NetduinoDeploy Known Issues. At the beginning of this default code generated you will see some libraries are included this are also called references which are Like for our blinking code we require only the following libraries So our final blinking code for the onboard led on the Netduino3 Wi-Fi board is Copy paste the above code inside the program.
Click on the "Properties" tab and check the Target Framework is. Net Micro Framework 4. For the internet connection part i have the used the code available here. References Required for this project are shown in the below image; installL it before clicking on the "Start" button There are two classes in our project - Program and App. Since Netduino has sophisticated multi-threading support especially for an MCU platform , it's useful for a more elegant solution that also saves on power consumption.
Class App has network connection functions some of which are protected while others are Public. Only the Public functions can be called from other class. Prints each Network Interface for e. To check which Interface for e. This function is made public so that we can call it inside our main function situated in the Class Program. This is similar to the MakeWebRequest function except that it takes the sensor's values to upload it to Ubidots. Only two sensors data can be uploaded using this function.

To get the values of a variable using its label, make a GET request to:. I am concerned only what is the last value which is return to the control variable. To get the last value of a variable using its label, make a GET request to:. This code automatically will create a new device inside the Devices Tab of Ubidots account with all the variables as named inside the code. But to do so you have to change the token inside the code with your ubidots account token key. Now if you click on the Devices tab you will see that a new device is created but still your program will stop abruptly.
Since the uploading sensor variables like air quality, light level and temperature is created automatically when you upload a value to this variables. But the control variable "relay1button" for which we are requesting Ubidots to receive it's last value is not present so you have to manually create it. Now to visualize the sensor data and the button for our control variable we have to create widgets inside our Dashboard in your Ubidots account.
After completing all the widgets in your Dashboard always click on the control variables widgets so that they can have some default value which you can read using Netduino. Let's write a code to control our on-board led using the relay1button widget we created on our Ubidot's Dashboard! Now the main part where the LED Control takes place based on Ubidots "relay1button" widget is inside the main function in class Program.
Outside the continous while loop we first intialize the led pin to low or we turn it off. Then inside the while loop you check continuously after every milliseconds for the last value of the "relay1button" variable which can be changed by clicking on it's widget present in Ubidots Website Dashboard or it's Smartphone application.
When you click the "relay1button" widget you either send 1 i. You can add as many Relays as you want but since this is a prototype i am using a single relay! Now let's change this code to control a actual LED Bulb using relay. It's very easy just add a relay to a digital pin i. First intialize the pin to which relay1 is connected and then let it be initially turned off because we will control it via the Ubidots IoT platform Now inside the while true loop instead of controlling the on-board led we will be controlling the relay pin. Now you should connect the relay to digital pin D2 and hear a click sound whenever you turn it ON using the Ubidots website or App.
Connect anything you want to control to this relay and voila your home automation project is ready. It's upto you what you want control! References you require for the analog read functionality on Netduino I used below Arduino code as reference to make C code for Netduino! All the Grove sensors and modules we connected works fine when provided power supply of 3. The sensor seems to work fine when provided 5V via Grove base shield but not at 3.
I am facing this problem i don't know the exact reason since the sensor working voltage is specified as 3. As digital pins of Netduino are 5V tolerant i can keep the Grove base shield voltage switch towards 5V side but the problem lies with Analog pins which are not 5V tolerant and hence can get damaged so i was successful in interfacing the sensor to Netduino but right now will not incorporate it in the final demo.

Dashboard Link Shareable link. First to make sure to have a 3. Make the code more efficient like using timer function to call for reading the sensors and uploading it at periodical intervals, etc. Hey guys i tried my best to make you understand how i made my smart home prototype and i hope you understood everything what i have presented here. There was so much i want to explain but it seems this page will not end. It was my first time working with Netduino and with Visual Studio; faced a lot of problems but at last the project was completed and i am happy with the result.
