Dear friends Warm greetings. I am quite new for FriendlyArm and even new in hardware system design. i am planning to work on the wireless Sensor Network for flood monitoring and agriculture monitoring. I need to setup Ultrasonic water level measurement sensor and VGA or any camera in the field. The sensor should be connected to some system so that the system can read the data from ultrasonic sensor and camera and store it temporarily and send it to the web server through the 3G/Wifi or any other internet service. The user should be able to see the status of the sensor through the internet or locally. I am thinking to use FriendlyArm as a platform that can control field sensors, get data from them and store on the SD card or data logger.I have attached the schemetic of the system on the picture. I need some sugessions whether i can use FriendlyArm to realize this system or there are any other best options in the market. I hope to get your good suggessions. Thank you. Regards Babu
