About this project
Meet the Daisy WiFi: a small, low-power network device with sensors and controls. The Daisy enables you to connect sensors and controls to the Internet for monitoring and controlling your world. You can create automated actions that are triggered whenever a sensor reports a specific value or crosses a threshold.
- Call my phone if the temperature in my house drops below a specified value
- Send me an email if the door on my mailbox was opened (i.e. mail arrived)
- Send me an instant message if a leak is detected in my basement
- Automatically open your garage or pet door as you approach home
- Toggle a device on and off from your phone, tablet, or web browser at work
- If the Daisy in my basement detects a water leak, trigger another daisy to shut off the water main and send me a notification.
There is so much you can do with this little device; these are just a few examples. The video demonstrates many examples of ways we tested the Daisy, but it only scratches the surface of possibilities.
We have been tinkering and testing devices for almost a year now, and we're looking for help from the Kickstarter community to bring the Daisy to production. We're also in the process of creating software that allows you to interact with the hardware. You'll be able to view your devices real-time, as well as create rules that execute when your device reports its sensor data. We have a prototype demonstration available at http://live.daisyworks.com and the rule editor can be found at http://live.daisyworks.com/editor.html. Note that the website is setup for demo purposes only. We have disabled communication with real devices while we continue development on it and add features.
We have created a few different versions of the Daisy WiFi and Daisy Petals. Daisy Petals are boards that snap onto the extendable Daisy WiFi base and fit inside the case (think pop-top). This gives you additional hardware versatility by adding more sensors and controls just by swapping out a different half of the outer case. We have built and tested a Daisy Petal that can be optionally be populated with:
- Infrared temperature sensor
- Digital temperature and humidity sensor
- Light sensor
- Extension ports (I2C, 1-Wire, SPI)
Extension ports allow for connecting additional sensors and controls outside the case. You can even connect a Daisy to an Arduino or Arduino-compatible device http://arduino.cc. In the video, we connected the Daisy WiFi to an Arduino for the dog kennel demonstration -- it is easy to do. We'll be adding ample documentation to show you how to do similar things.
We also plan to open source the hardware and the software so others can build on top of this platform for whatever purpose they desire.
Our aim is to provide at least two free years of access to anyone who backs us on Kickstarter. That means we'll store your sensor data for free, and offer you unlimited access to our services during that period. In the future, if we can't continue to provide free access, we may charge a nominal fee as necessary to cover maintenance, hosting, and other costs. Your data will always be free: we will provide you a way to export all of your data so you can back it up yourself, or move it somewhere else, should you choose to do so.
Kickstarter: please help us bring this idea to fruition. We have been planning this for a long time now, we have a great head start, and we're really excited and passionate about building this. We want this in our own homes -- this is one of our primary motivators, but we'd like you to have it too.
Under the Cover
Daisy Petal (pop-tops)
Daisy Petal extensions plug onto the top of the extendable Daisy WiFi and fit inside the case. We've successfully interfaced and communicated with each of these sensors, however, we still have some programming and testing to do. We'll ship these when they are ready for prime time.
- Motion/Vibration: triple axis accelerometer. Add $40.
- Infrared temperature: non-contact infrared temperature sensor. Add $55.
- Temp./Light/Humidity: digital temperature, light, and humidity sensors. Add $45.
- Breakout board: Provides interfacing and prototyping area for your own circuits. This is how we connected the smoke alarm. Add $15.
We've tried to make connecting the Daisy WiFi to a network easy. If your WiFi supports WPS, just push the WPS button on your router and activate WPS on the Daisy WiFi and it will self configure and connect. No fumbling with pass phrases or hex codes.
If you don't have access to your router or you have an older router which does not support WPS, then you'll have to activate and connect via ad hoc mode to configure it with our form based configuration utility. This will require entering your security pass phrase or WEP key. Don't worry, we'll post a HOWTO video and document it clearly to make it as easy as we can.
Our prototypes currently use a single AA sized 3V Lithium battery which costs less than $2. While we expect typical battery life to be many months and possibly a year or more, it is highly dependent on how the Daisy is configured and used. Of course the Daisy has a built-in battery level sensor, so it can notify you when the battery is running low and needs to be changed.
Current Prototype Size
- ~70 x 51 x 21mm
- ~2 x 2-3/4 x 0.8 inches
- IEEE 802.11 b/g
- Security WEP, WPA, WPA2
- Ultra low power
- Certifications: FCC, ICS, CE, Wi-Fi Alliance
To responsively and continuously control outputs, the device must stay in active mode where it consumes more power. Controlling relays also consumes substantial power. Due to these two factors, if you plan to control outputs or relays, external or USB power is highly recommended, otherwise, the battery life will be severely limited.
The WiFi module in the Daisy can be configured to communicate via TCP/HTTP or UDP. If for any reason you want to try the device with your own application or someone else's service, you are welcome to use our configuration utility to configure it to connect and post sensor data wherever you like.
The Daisy WiFi comes standard with an internal antenna. If you prefer an external antenna, add $10. The Daisy comes with one or the other, not both.
This is a closer look at the experimental outlet we mentioned.

We've tested other use cases as well and we'll continue to do so. We plan to post those as updates.
There are a few key advantages to the Daisy system:
- The Daisy is a bit smaller and has more sensors and sensor options than others.
- Daisies have output control pins to interact with your world, not just listen.
- New sensors and processors can be added that fit inside the case, it is not required to have cables and external boards to add additional sensors and controls.
- We plan to open source the hardware and software so others can customize and help improve and evolve the ecosystem.
- Optionally the Daisy can have an external antenna to allow remote location and/or orientation. This facilitates communication outside of metal enclosures or other challenging environments.
- The prototype Rules editor supports complex Daisy to Daisy interactions.
- We have prototyped location based interactions which we haven't seen in other products.
Overall, we believe our proposed offering provides more value and flexibility.
