“A prototype that seeks to give intelligence and magic to the lights of cities of the future using Cayenne and Sparkfun ESP8266 dev. Story Introduction Smart cities are the result of the ever more pressing need to orient our life …
“In this post I’m going to show you how you can monitor the power consumption of your battery driven (ESP8266/ ESP32) device. Measuring the power consumption over a full activity/ sleep cycle is the precondition to optimize your code …
“Monitor a remote system (battery, power usage and sensors) with this Arduino MKR FOX 1200-based, Sigfox-connected solution. My garage has no mains electricity or WiFi and so I use an old car battery for power and LED lighting, I’d …
“This is a unit that can monitor 10 single cells or 10 battery packs and print data in graphs on excel. I was asked if i could come up with a way to measure and test multiple cells or battery …
“This instructables show how to visualize the circuit design in real life.”
“This instructables show how to make a simple power meter using 3 components: ATtiny85, INA219 and OLED module. It can continuous measure the voltage(V), current(mA) and accumulated power usage(mWh). And also plot a simple graph to visualise …
“Solar power meter measures the voltage, current and power of my 40W solar panel. On the PCB are two electrolytic capacitors, connectors, 3.3V stabilizer, ESP-01, voltage and current sensor INA219. OLED display is screwed to the box. The …
“In this project I will show you how I combined an Arduino, an INA219 power monitor IC, an OLED LCD and a Micro SD Card PCB in order to create a power meter/logger that has more functions than the …
“The idea was simple enough; create a phone charging dock that would turn on a lamp only when the phone was charging. However, as is often the case, things that seem initially simple can end up getting a bit more …
“Controlling the electrical consumption in your home is one of the most important thing you can do, both because of environmental concerns & to reduce the electricity bill at the end of the month. There are countless of electrical power meters …
“Another small board, this time for a INA219. The INA219 is a high-side current shunt and power monitor with an I2C interface.”
