IoTek provides different types of sensors connected using propriety global connectivity GSM technology allowing the user to detect events or changes in its environment, and then provide a corresponding output.
The board is powered by a Cortex-M0+ MCU from NXP.
32-bit ARM Cortex-M0+ microcontroller; 256 kB flash and 36 kB SRAM; 4 kB EEPROM; 12-bit ADC
The preliminary list of sensors is shown below:
Pressure Sensors Digital Barometer 2.7uA, 300-1200hPa
Color Light-To-Digital Converter with IR Filter
Infrared Sensor Thermometers
9-Axis (Gyro + Accelerometer + Compass) MEMS MotionTracking Device

The main feature of this board is the M2M connectivity that comes with it. The board is equipped with a GSM modem and a Global sim-card that works all around the world. The data transfer is not limited by data caps no matter where you are in the world. Once might think that this kind of connectivity comes with a big bill to pay, well that is not the case here. The final pricing is not set yet since a deal is not yet set with the provider.
More details about this part will be provided at a later time, you will have to trust me for now.
The board will come with some free WEB services, I didn't finalize the list yet for these services. But the user will surely have a dashboard and webpage to display the collected data. The user can then make the webpage available to the public or keep it private. More web services will be introduced as we go, and based on any feedback we will gather here.
No Technical Background :
The board is aimed at people who do not have any technical background as well as technical people. The board programming will be done easily using a graphical web platform, the firmware is then transferred to the board using the M2M connectivity without any need to connect the board to the PC at any time.
Many variations of the board should be available. Not all users need the same sensors, so the user should be able to choose a list of the sensors that will end up being on the board he will buy. The full board will have all the sensors packed together, if the user chooses so, he can get a board with some of the sensors not assembled.

The board will be equipped with a wireless connectivity. The aim of having a wireless connectivity is to save the user from buying multiple subscriptions. With the wireless connectivity the boards will communicate with each other and only the one equipped with the GSM modem will transfer the data to the server.
This is the main idea, I would appreciate any feedback on the basic idea. More details will come as we go. For now I came up with the CAD drawing of the board. The proposed dimensions of the board are to be 5x5 cm. You can see a snapshot of the drawings in the project gallery. Once the drawings are finalized I will share the original drawings in CAD format.
