ESP32 + OLED in a 3D printed DIN case polling a Shelly EM on the LAN, no Home Assistant: watts, voltage, kWh history, siren, web UI.
LED panel showing live household watts read from Home Assistant, 3 colour thresholds, buzzer alarm, web UI and OTA.
Monitor, inspect, and safely control the power-management functions of an i. MX 8M Plus system using the NXP PCA9450C over I²C.
Power management for portable Arduino projects.
A setup to power a Raspberry Pi along with a USB Hub to power upto 4 external USB Hard Disk Drives for a home theater system.
Designed for Industry 4.0, but suitable for smart home too. Features WiFi control, current measuring, PWM, soft start / stop and safety.
Attach your solar inverter to the cloud and send your family alerts when they are using too much power (Warning, they wont like it).
Designing a powerful digital AC dimmer using an STM32.
This project is a "from scratch" DC regulated benchtop power supply intended to be used by an electronics hobbyist.
WIZnet W5100S + Raspberry Pi Pico + PoE It's a board that I developed. I'm introducing it again because I'm using it for so many projects.
How much power does an everyday appliance use? How can we look at and interpret this data?
This is a monophasic and biphasic residential consumption monitoring meter using the ESP32.
With this novel inverter design, an Arduino Nano replaces a lot of hardware, resulting in a simple pure sinewave inverter circuit
Usually, you might use WiFi to control your IoT projects at home, but what do you do when your WiFi is down?
12v Solar Generator using a Victron BlueSolar MPPT 75/15 Solar Charge Regulator & Arduino-based GUI for Info Display.
Use two transistor to dim a 12V ledstrip with a mkr1000.
With a code size of 1KB on an ATtiny13A MCU, this tiny module measures voltages up to 22 volts and current up to 5 amps.
Control your 3D printer with voice commands using Snips and Matrix Voice!
Open source DC boost converter module designed around a single cell lithium battery: 3.7 V in, 5 - 24 V out.
Power monitoring system capable of many types of measurements including both loads and supplies such as solar photovoltaic systems.
I plan to put an ESP8266 inside a 4-outlet power strip. It will monitor the current draw from each of the 4 outlets and notify me.
In this opportunity we will integrate our active power meter or electric consumption, Peacefair Pzem-004 with the IoT Blynk app platform
I made this dual channel stereo 28watt amplifier in on a small cute PCB, Powered by external 18v dual power supply and has very good audio.
This project is very help to measure the voltage ratings of a zener diode, Get PCB Gerber and circuit schematics from here.
