Passive Wi-Fi – Bringing Low Power to Wi-Fi Transmissions
https://www.electronics-lab.com/passive-wi-fi-bringing-low-power-to-wi-fi-transmissions/
Bryce Kellogg, Vamsi Talla, Shyam Gollakota, Joshua R. Smith have published an research article discussing Passive Wi-Fi transmission that consumes 3 – 4 orders of magnitude lower power than existing Wi-Fi chipsets. Passive Wi-Fi transmissions can be decoded on any Wi-Fi device including routers, mobile phones and tablets. Building on this, we also present a […]
Hardware serial port monitor over WiFi
https://www.electronics-lab.com/hardware-serial-port-monitor-with-wifi/
This tutorial shows how to connect Arduino to the TX line (of a router, RPI) and display serial data on smartphone over WiFi. Arduino listens for serial port communication on its hardware serial port. Then it sends every received line of data trough software serial port to ESP8266. ESP8266 puts every received line of data […]

Dan Watson @ syncchannel.blogspot.com wanted to have more fun with his MightyOhm Geiger Counter so decided to add an OLED display and Wifi capability to it. To achieve that he modified the counter, added a Feather HUZZAH ESP8266 with OLED FeatherWing and wrote some code. The process is documented on his blog: I assembled my Geiger […]
Wearable WiFi Detector
https://www.electronics-lab.com/wearable-wifi-detector/
A WiFi (Wireless Fidelity) is a technology that uses the 2.4GHz UHF and 5GHz SHF ISM radio bands to allow devices such as computers, smartphones, digital cameras, tablet computers, etc. to network. Nowadays the WiFi technology is being used by cities to provide free or low-cost Internet access to residents. The WiFi is inexpensive and […]
