This is an open-source hardware project aimed at creating an intelligent power extraction box for DELL server PSUs. It controls power switching, reads voltage, current, power values, and temperature inputs and displays them on an OLED screen. The device outputs 12V power through DC5.5 and XT60 interfaces for standard 12V devices.

RTC, Fan, OLED for Raspberry Pi, all stuff needed as a stable server/computer

ESP8266 WiFi Web Server control 4 Digital Outputs with OLED Display.

ESP8266 WiFi Web Server control RGB LED and OLED Display.

The project uses an ESP32, RFID reader (MFRC522), and OLED display to create an attendance system. It sends RFID card IDs to a server via HTTP for tracking and logging.

EMonitor is a ESP32 Microcontroller based device which gets environmental data such as Temperature, Humidity, Pressure, Light Intensity, and sends those data to a Back-end database server using CAP(Common Alert Protocol). Also those data and other connection status information can be viewed from the OLED-display locally. The data that were sent to the server can be visualized using a simple web-page. The device also features self fault recovery mechanisms to add more reliability to the system. EMonitor also sends a warning e-mail to pre-defined e-mail addresses in case of any sensor data exceeding a given threshold value.

It's a project combined with hardware and software, the goal is to make a smart watch based on esp8266 chip. The smart watch has so many features such as time display, alarm, brightness adjustment, text scrolling, weather display, voice control and gesture recognition:. The first five features time display, alarm alert, brightness adjustment and text scrolling are based on the local programming. The basic idea for these is to check the document for esp8266, getting to know how to set up the circuit, how to get the real time, how to control the OLED screen, bus, light sensors etc. The last three features mainly depends on the cloud coding, and are all based on the Client/server architecture. For Weather Display, esp8266 severed as a client. A connection was built by Google Geolocation API between the smart watch(client) and Google Weather Service Server(server). Send the JSON string including location information to the server and get the weather information back. For Voice Control, esp8266 was configured as a server by ngrok and an Android application was used as the client. This app aims to transfer voice signal into text commands by Google Speech API. Connected the app(client) to the smart watch(server) by HTTP request, and used translated commands to control the smart watch. For gesture recognition, esp8266 was client and server was the EC2 Linux instance set up in AWS. In order to teach the smart watch to identify gestures, both the training and predicting process needs to be done. Mongodb is used to keep the large amount of data from accelerometer training. SVM model is selected to do the training, the data for the same gesture was labeled. After training, if someone is holding the smart watch and moving it in some preset gestures, the smart watch could map these data from the accelerometer into a specific gesture. The final recognition accuracy is 98%.

The weather widget was built with ESP32. The weather information was gotten by open weather.com API. I got time from NTP server. All informations displayed it on 128x64 OLED.

In this project, we're gonna build an ESP32 analog clock with an NTP server's help and display it on an OLED display.

Here the server part of LoRa water level control: with this part you can control the pump and with OLED display you can chose the action, the client part check the level of the tank.

ESP32 - RFID Door Lock and Attendance with localhost database. Additional Features : Interface OLED 1,3" I2C, Real Time Clock and Date with NTP Server, Output Sound/Music with MP3 Module, Monitoring Room Temperature with DHT11

I decided to go one step further and build a multifunctional IoT thermometer with the ability to display temperature and humidity values on the Oled ssd1306 display as well as send data to the thingspeak dashboard. In fact, at the same time as the data is analyzed and the humidity and temperature values are displayed on the OLED display, then these values are sent to the thingspeak cloud servers and the values will be displayed numerically and graphs in relation to time and values.

Tiny daemon to display current mail server status on a $5 OLED screen

ESP32 LoRa Mesh Server is a minimal, professional implementation of a multi-hop LoRa mesh network with optional AES-256-GCM encryption and OLED status display. It provides easy-to-use serial commands, automatic message rebroadcasting, and low-memory footprint for ESP32 LoRa32 devices.

ESP8266 Client & NodeJS Server to stream arbitrary data into an OLED display

Suvi is a IoT device that bridges data from a server to the embedded OLED and a local network webpage.

In this project, I will tell you how to build an IoT based Fingerprint Biometric Attendance System using NodeMCU ESP8266 12E, 0.96” OLED Display & SFG R305a Fingerprint Sensor. The ESP8266 Wi-Fi Module will collect the fingerprint data from the multiple users and sends it over the internet to a website. The Enrolment of fingerprints is done on the server using any fingerprint sensor like R303, R305 or R307 that is available on the market and verification of the fingerprint will be done on the webserver while fingerprint templates are transmitted over the WiFi.

Fire Thermomist – A Smart IoT-based Fire Detection & Alert System An ESP32-powered fire monitoring system designed for sensitive environments like server rooms. Continuously tracks temperature & humidity using a DHT22 sensor and provides real-time fire alerts with buzzer and animated OLED visuals. Boot-time and weather animations .
