This is a simple WiFI Smoke Detector that texts me when it senses smoke. I made this for my battery storage area in case of a lithium polymer fire. I still have all of my regular smoke detectors installed and I don’t suggest relying only on this, but rather as an extra layer of protection. …
ITEAD has just released a new Zigbee 3.0 dongle powered by the Silicon Labs EFR32MG21 wireless MCU. The Shenzhen-based company, well known for its Sonoff line of home automation devices, had recently introduced a number of Zigbee compliant products like the Sonoff BASICZBR3 smart switch, the Sonoff ZBBridge WiFi to Zigbee Gateway, and the Zigbee-compatible USB dongle. ZigBee 3.0 USB …
AAEON, a leading manufacturer of network appliances and white box solutions, has released the FWS-2365 desktop network appliance. Designed with a range of powerful features including 5G support and four SFP+ ports, the FWS-2365 powers faster, smarter networks for SD-WAN and uCPE applications. The FWS-2365 is powered by Intel® Atom™ C3000 processors (formerly Denverton) with support for processors from four to …

A few years ago, one of Google’s hardware partners, TechNexion, launched a 2 board development kit that consists of a System-on-Module and a carrier baseboard – the PICO-PI-IMX7. PICO-PI-IMX7 is a highly-integrated single board computer with enhanced features designed to enable secure and portable IoT applications. It is aimed at facilitating fast prototyping and product development at predictable scaling …

Today we are going to show you our first experiment on the Internet of Things. For this purpose, we decided to use an Arduino MEGA instead of an Arduino UNO. That’s because Arduino MEGA has more than one serial port and this fact allows us to use the ESP8266 and the serial monitor at the …

Adafruit has teased us with the announcement of the panel-mount TFT ESP32-S2 Wi-Fi Feather Board. It appears to be a succeeding version of the previous ESP32 Feather boards, by changing few positions of the components like the ESP32 module and USB-Serial converter, with the ESP32-S2-MINI module. Apart from the NeoPixel in the schematic diagram, the STEMMA-QT header fits in the middle of …

Introduction In our final project, we used CMOS camera to identify interval binary 0 and 1 sequence represented by black and white bars. Then, we used WIFI module to transmit the sequence to personal computer and displayed it on a web page. In our projects, we chose OV7670 CMOS camera and ESP8266 WIFI module for …
This project aims to implement a protocol-compatible iClicker substitute to provide students with a cheaper alternative to in-class polling while allowing the university to keep its existing investment. High Level Design Rationale Our motivation from this project comes from our personal experience. iClickers are inconvenient and expensive yet required for at least one class at …
Broadcom’s BCM4389 chip is a client-side device supporting Wi-Fi 6E and Bluetooth 5 combo dedicated to mobile handset applications. The Wi-Fi 6E technology can operate on the 6 GHz band with 160MHz wide channels which is a progressive version of the Wi-Fi 6 technology. Hence, it enables speeds over 2 Gbps for faster communications than the Wi-Fi 6 that supports from 2.4GHz to 5GHz radio bands. …
