Sensor That is a Wireless Sensor Network made up of the web application sensorthat.com the Sensor That Gateway and Wireless Sensor Modules this brings the Internet of Things to you.
How Sensor That works...
Sensors either wake up and take a reading or sense an event. Data is then sent via the internet by the ST Gateway to the sensorthat.com web application where the reading or event is recorded. Depending on the the If This, Then That ( IFTTT ) rules setup, notifications are then sent out.These notifications can then be used to respond or control various changes in your world or environment.
This system is designed around the idea that each device should only be responsible for one sensor. Not only does this simplify the whole system. It also does not make any sense to put all kinds of sensors into a single sensor block. This does not allow for a related sensor to be strategically placed in a location where it is going to be most effective. It makes more sense to place a leak detection sensor low down on the ground or on the floor. However measuring temperature at the location would not necessarily be the best idea. Here is a list of sensors we are working to create and will be available as part of the Sensor That packs.
Sensor That Web Application
The web application sensorthat.com is a Responsive web design (often abbreviated to RWD) is a web design approach aimed at crafting sites to provide an optimal viewing experience—easy reading and navigation with a minimum of re-sizing, panning, and scrolling—across a wide range of devices (from desktop computer monitors to mobile phones)
What are the advantages
of a Responsive Web Application vs. native apps? A Responsive Web Application has a number of inherent advantages over apps, including broader
accessibility, compatibility and cost-effectiveness.
Apps on the other hand require the user to first download and
install the app from an app marketplace before the content or application can
be viewed, a significant barrier between initial engagement.
Alarm and Event notifications are sent out via SMS, Email, Twitter.
The ST Gateway is a drop in wireless network solution and requires no programming. This allows for a wireless sensor network to be created in minutes.
Just connect the ST Gateway to any active internet connection
using a Ethernet cable and power it up. Now just join your sensors to the wireless network and just like that they are now connected to sensorthat.com. However if needed the ST Gateway also has a easy to use web based admin interface.

Sensor Battery Life
Battery life may vary depending of the type of sensor. Each sensor will require one 3 Volt Lithium Ion battery. Sensors are ideally programmed to wake up every 5 minutes and take a reading then the go back to sleep. If a device has a temperature sensor the battery could last up to 2 years. A device that is programmed to sleep and only wake up on an external event would have a very, very long battery life.
ZigBee Packets being transmitted over the internet are encrypted. With Sensor That there is no risk of someone hacking in and taking control.
The PCB for the Sensor That Gateway is a 4 layer board consisting of 1 Ground plane 1 Power plane and 2 Signal layers. The PCB for the Sensor That Gateway and Sensor Boards will be produced in Korea by the same company that was used for creating the Prototype PCB. They are very cost effective, competitive and reliable and can deliver a large volume of Printed Circuit Boards within 2 weeks. During this time parts will be sourced. The final Sensor That Gateway Kits containing sourced parts and PCB will be assembled in about 7 days in Shenzhen, China.
Once received, the populated ST Gateway Boards will require flash programming depending on volume that will take about another 2 weeks and will be done in Kelowna, Canada.
The ST Gateway main enclosure will be made from extruded aluminum. This keeps cost down by not needing any plastic molds. Only the Front and Back panels require any manufacturing. Front Panel Express was used to manufacture the Front and Back Panels for the Prototype Enclosure needed for the Sensor That Gateway. Since they did such a great job and offer a 5 day turn around, they will be used for production.

How will the funds be used?
Help manufacture a mass quantity of ST Gateways
Help create and design all kinds of various sensors
I have been working as a software hardware developer for well over 10 years. I have always been interested in connecting things to the Internet this was even before the term IOT (Internet Of Things). More recently I have been working with ZigBee wireless networks and the Ember ZigBee Stack.
Inspiration came from wanting to find a way to more easily start working with Wireless Sensors without any programming, development and have a full featured sensor network application ready to use. I have been working hard on Sensor That and believe I have created a dead simple way to start monitoring almost anything.
Do you have something you would like to monitor, your home, maybe the environment? Sensor That is almost complete I just need your help.
Risks and challenges
A substantial amount experience and time is behind this project in the area of testing and supporting embedded systems designs and web applications.
The ST Gateway firmware and the Sensor That Web Application have been thoroughly tested. However there could be some issues that come up. Any software issues that may come up are only expected to be very minor.
Printed Circuit Board and components lead times could cause delays we are working with our manufactures and parts distributor on such issues.
The Sensor That web application was designed using the latest web technologies, PHP, MySQL, CSS, HTML5, JQuery, Ajax, Java Script and Responsive Web Design (RWD). Sensor That is also hosted on a cloud server, this makes it very scalable. Scalable is the ability of a computer application or product (hardware or software) to continue to function well as it (or its context) is changed in size or volume
Sensor That is very secure, the Sensor That web application uses SSL (Secure Sockets Layer) this is a standard security technology for establishing an encrypted link between a server and a client, typically a web server (website) and a browser. Packets transmitted between the ST Gateway and the Sensor That Sensor Daemon are also encrypted. Also ZigBee supports 128-bit AES (Advanced Encryption Standard) encryption to encrypt data on a ZigBee network.
