This is an Android data logger using a remote Arduino with Ethernet Shield attached. Data logging with a standalone Arduino has limitations such as lack of RTC and lack of multi-threading(needed to access data and log simultaneously). So a neat solution is to do the logging on a device that can multi-thread while leaving the analog port reading to the Arduino. The Arduino listens for a client to connect, and upon the client request, sends a reply back to the android device with the sensor data. The image on the right shows my sensors (s0,s1,s2) and the temperatures. The sensors are linear active thermistors MCP9701.
