5.4 IoT Temperature and Qtouch Sensor Demo

The purpose of this demo is to connect various kinds of sensors to your home network using a Wi-Fi access point and remotely access the sensors' information via an Android device.

A sensor typically implements a basic discovery system where UDP broadcast frames are sent each second to advertise the sensor presence on the network. The Android app can then detect such packets and communicate with the sensor to receive the sensor data stream.

These are implemented in a similar way and use a similar communication protocol with the Android application. Both can work at the same time and report sensor information to the same “Atmel IoT Sensor” Android application.

Note: This example application is not available in ASF for ATWINC3400.
The Temperature Sensor Demo is based on the following hardware:
  • The SAM D21 Xplained Pro
  • The ATWINC15x0 on EXT1 header
  • The IO1 XPRO board on the EXT2
  • The QT1 XPRO board on the EXT1 and EXT2
The Qtouch Sensor Demo is based on the following hardware:
  • The SAM D21 Xplained Pro
  • The ATWINC15x0/ATWINC3400 on the EXT3 header
  • The QT1 XPRO board on the EXT1 and EXT2
Note: The Qtouch mutual capacitance QT1 XPRO board needs to be connected to EXT1 and EXT2 header together.
