About this project
DustMotes : A small-sized platform for all Wireless Sensor Network Enthusiasts:
Greetings from ANTFARM INC.! We are working on Wireless Sensor Nodes and making them available to the DIY community at a low cost, which allows you to make your own kickass wireless project for your Home, Office (or any other place that you see fit). We are also bridging the gap between WSN and Internet of Things by providing a App between your SmartPhone/Tablet/PC and your WSN. And all you need is a single router connected to a server which can control upto 255 devices (nodes/motes)!
Each Mote is 1 sq in. and can be supplied by 3xAA’s or a battery of your choice above 5V.
Batteries are not included.

Basics : What is it ?
Okay,first of all a 101 on WSN. WSN is a cluster of wireless nodes which act as sensor or actuator interface and is spread over an area. There are few nodes called Co-ordinators ( Routers in our case ) which are used to control and manage the Network. You can command each node to be a sensor or actuator in our case and we have a free API ( AT command based ) which allow you to do the same. More on that later. A typical use case is : You connect a humidity sensor to one of the nodes and a Water valve controller to another. And you want the valve to open water whenever the humidity is low . Well hook up your sensors , pop in our Router into a PC and write some code using our API and voila! You have an automated watering system!
- General Home / Office Automation : Connect analog sensors , plug-in batteries and place them anywhere to have your own sensor network. Moreover, design a Switching board ( Triac based ) and connect your AC appliances to it and control using the Web interface.
- Habitat Monitoring: Hook up sensors and sense environmental parameters of your home or your pets home .
- Security : Hook up a PIR sensor , or a Contact Sensor to your Doors , Windows and get alerts whenever there is movement in your monitored place or opening/closing of Doors.
- Autonomous House : Walk in and the lights /fans switch on automatically depending on the time of day and other rules defined by you!! Use our rich API to define the rules, all you need is serial port access! Use a language, OS, Software of your choice!
Made for DIY Guys ( and Gals ):
Dustmotes ( okay , they are not Dust sized, but we will make them tinier in the future ) are made for the Developers . Whether you want to make an app to control Electrical fittings for the elderly or you want to keep a temperature controlled Greenhouse, Dustmotes gives you the power of commanding everything remotely. Hook up analog sensors to have your data streaming in and stored to your choice of database. No Monthly fees! You own your data, Always !
If you need help with a Power Electronics Board for a particular Application (in volumes ), we can help you out too.
And Dustmotes is made with some of the coolest and tested technologies around as below :
An Ideal Server for the Dustmotes is the Raspberry Pi. Plus the router to the USB port , Put it safe somewhere , and plug in our Raspbian Image. You’ll get an instant access through apps to all your Nodes/Motes! Zero-Coding Too!
Our Design Journey :
We started working on Swarm robotics back in 2009 and soon realized that we would need a proprietary network to support the Bot-Bot Communications. Thus we started work on WSN as an affordable option to WiFi. We don't need high data rates but need to support a large number of nodes and be power efficient , thus WSN fits us fine. We developed most of the codebase on development boards and some hand soldered prototype boards as shown below :
On the above ATMega640 board we developed our RF Stack for CC2500. Initially we were ad-hoc command based , but we soon thought of standardizing it with our "ANTFARM AT Commands".
Next , we had to standardize the Response , and we chose JSON for its popularity and ease of parsing. Here's a snapshot of our early discussion :
Right now , we are ready with two kinds of boards as shown below : the Router and the Nodes.
What exactly is the Router ?
The Router is a FTDI230X + ATMEGA328 + CC2500 Combo which allows : Streaming of AT commands over the serial port ( and response , that too in JSON! ) Scanning for nodes Connecting to any Node using our API Configuring any node to a desired setting The router plugs into any standard USB Type-A port like a dongle. The FTDI takes care of the handling of USB packets, so its just a COM port to you! The CC2500 is a radio transceiver by TI , which is the backbone of this system. You don't need to worry about the radio packets , our router and nodes do it for you.
What exactly is a Node?
Each Node is a ATTINY85 + CC2500 combo which allows: Control of a Single 0-3.3V Actuator , OR Sensing of a 0-3.3V analog Sensor, OR Sensing of a inbuilt Temperature Sensor.
Just Power the Nodes with any battery source > 5V and < 12V. Nodes log in data to the router at a LOGGING_TIME interval , which is configurable. Nodes which go down are easy to detect at the Router.
Please see the following videos which showcase the operation of the system as well as the API .
Are High Voltage Switches included ?
We decided that we will not include high voltage switches ( or sensors for that matter ) as they are a very custom requirement. Someone might need a 5V 1A switch whereas someone might need a 110V 15A switch. Dustmotes is made such that you can easily hook up Triacs ( Or MOSFET’s) after a optocoupler such a MOC3021. If you have a large enough requirement , contact us and we will help you will design integration.
What will you get :
You will also get this awesome app below ( On Web, ioS and Android )which will let your Dustmotes work out of the Box with Zero coding!
For the Code Lovers:
What is the AT Command API ?
- $$$ //Go To Command Mode
- ATCN 31 //Connect to Node 31
- ATAC 1 //Turn it ‘ON’
- ATND //Get out of Command Mode
What is the REST API ?
So, say you want a REST API, no sweat! Hook up our Router to a Raspberry Pi and download our Raspbian Image with all the right stuff setup . Burn it to a SD card and you have a WiFi Hotspot called “Dustmotes”. Connect to it and you will get the REST API access. Make your own Apps, deploy it somewhere either personally or professionally. No monthly fees to be paid!

Risks and challenges
We need to raise 50K$ to cover our Manufacturing costs. We will be manufacturing this project in India and will be shipping to the US.
We are currently in talks with Fulfillment agencies based in the USA as a logistics partner to reach our consumers in the USA. This agency will take care of clearance through Customs, all documentations and domestic shipment until the product reaches your home! Minor delays due to the customs clearance process might affect the actual date of final delivery to you.Learn about accountability on Kickstarter
