IOT Home Automation Sensor Network

For quite some time i have been working on my Project to provide a 100% Arduino compatible Sensor network . In the next few weeks i will be selling the devices at the moment there will be the main unit Arduino board with onboard 868 MHz transceiver and EEPROM or hardware encryption (ATSHA204A) PIR Motion sensor and a vibration sensor(glass break sensor), also to make things easier a programming board. next will follow a board with (Light, Air pressure ,humidity ,and temperature sensors) also a board for measuring PH levels .

All devices are stackable . For further information ( www.widuino.com) Best regards Simon

This is the board that i have been working on.

So what do you think Regards simon

Id be happy to here some comments ,or ideas .
