Description “This project detects metal objects using a proximity sensor with ESP8266 and DS3231 RTC, then reports the status with timestamps over MQTT.” D2 (GPIO4) Proximity Sensor Input sensor pin ...

With progress slowly being made on turning the ESP8266 UART to WiFi module into something great, there is still the question of what the range is for the radio in this tiny IoT wonder. [CNLohr] has ...

A NeoPixel ring with 60 RGBW LED’s connected to an ESP8266 gives us a clock using NTP server to get the accurate time. No external RTC needed. The time lib that is integrated in the ESP8266 core gets ...

Prelude: Imagine a distributed cloud spread all over your campus. The main server is sitting somewhere on Internet (or Intranet) and maintaining a big database having a huge number of tables. The tiny ...

// 1. Menggunakan WiFiManager untuk koneksi WiFi tanpa hardcode SSID & Password. // 2. Menggunakan RTC DS1307 sebagai backup waktu jika WiFi tidak tersedia. // 3. Menggunakan NTP Client untuk ...

Support libraries, good application notes, and worked examples from a manufacturer can really help speed us on our way in making cool stuff with new parts. Espressif Systems has been doing a good job ...

Abstract: A wireless sensor network (WSN) is a significant technological element of the Internet of Things (IoT). The core of a WSN consists of wireless sensor nodes (IoT nodes) that collect and ...

PCB Studios has just launched the “Flipper Zero ESP8266 Deauther” adapter board for Flipper Zero that enables users to conduct de-authentication attacks on Wi-Fi networks. Running a modified version ...
