Wireless Analog Data Acquisition System

A wireless analog data acquisition system. The main component of this system is an external hardware controller that interfaces with an Android mobile device. Various analog sensors such as pressure sensor, distance sensor, light sensor, temperature sensor, and many others can be used. These sensors are connected to the controller. The analog data from these sensors are first digitized and then sent via Bluetooth to the mobile device. The data is plotted in real time on a graph and also saved to a file for future analysis. Two trigger alarms can be set. Various alarms connected to the output of the controller are activated when the data is within the alarm thresholds. You can download this free Android app from the Google Play store.
