💧 Monitor water levels wirelessly with an ESP-NOW system, using ESP-12F and NodeMCU for real-time display and alarm notifications without Wi-Fi.

Tapping the 'Tmoney' card to the NFC module displays the remaining balance on the OLED screen, offers the most intuitive way to check the balance on the card.

ESP-NOW Water Level Monitoring System A wireless water tank monitoring solution using ESP8266 boards and ESP-NOW protocol. It measures water levels with an ultrasonic sensor, displays data on an LCD, triggers alarms, and supports OTA updates—no Wi-Fi router needed.

This project use a NodeMCU esp8266 It scans specific WiFi channels for deauth packets, When an attack is detected, it activates an LED and a buzzer while displaying relevant information on an OLED screen.

A ESP12 controlled Nixie Tube Clock

🌡️💧 An autonomous, solar-powered weather station built with ESP8266 (ESP-12E). It measures temperature, humidity, illuminance, dew point, and heat index using HTU21D & TSL2561 sensors, and sends data to ThingSpeak every 15 minutes. Includes Deep Sleep for energy efficiency and a 3D-printed enclosure for outdoor use.

RoundyFi animated eye

An FM radio receiver built using an ESP12E, interfaced with the RDA5807M module. Powered by a Li-Ion battery with a TP4056 charging module, amplified by a PAM8403, and output through a 10-watt speaker. Features station switching via a button.
