A proposal of low-cost and low-power embedded wireless image sensor node for IoT applications Tresanchez Ribes, Marcel Pujol, Alain Pallejà Cabrè, Tomàs Martínez Lacasa, Daniel Clotet Bellmunt, Eduard Palacín Roca, Jordi Image sensor Video streaming ARM IoT sensor node This paper proposes the design of a low-cost, low-power and small size image acquisition device to be used in Internet of Things (IoT) applications which collects, processes and sends image data through a 2.4GHz Wi-Fi connection. The proposed processing unit is a low-cost high-performance STM32F7 microcontroller which is able to acquire and transfer images at full rate keeping the core idle to do image processing. The device is supported by a 1.3 Megapixel CMOS camera sensor, and a low consumption Wi-Fi module. This setup allows to create a very compact image sensor device with a built-in processing algorithm for a specific functionality in IoT. In this work, the device hardware architecture is described and discussed, and a comparison with alternative hardware solutions are presented. 2018 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a https://doi.org/10.1016/j.procs.2018.07.149 Procedia Computer Science, 2018, vol. 134, p. 99–106 cc-by-nc-nd (c) Marcel Tresánchez et al., 2018 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Elsevier
