ESP8266 mains energy monitor
https://www.electronics-lab.com/esp8266-mains-energy-monitor/
Brian Dorey has designed a mains energy monitor based on ESP8266 that have sensors for the mains current, electric meter and gas meter. As the new solar logger did not have this functionality we decided to design a new data-logger that would measure not only the mains current usage but also keep track of the […]
Nixie Tube Energy Meter
https://www.electronics-lab.com/46760-2/
John Whittington decided to build a Nixie tube energy meter to measure his house power consumption. An Arduino would be the microcontroller but I wanted the meter to provide some form of data stream for a web based energy history. To make it an IoT, I a paired ESP8266 with it. I used both together […]
LTC4282 – High Current Hot Swap Controller with I2C Compatible Monitoring
https://www.electronics-lab.com/ltc4282-high-current-hot-swap-controller-with-i2c-compatible-monitoring/
The LTC4282 is an energy monitoring Hot Swap controller with dual MOSFET drive to enable 100A and higher current board designs. The LTC4282 ensures safe board insertion and removal from live 2.9V to 33V backplanes by controlling external Nchannel MOSFETs to gently power up capacitors, avoiding sparks, connector damage and system glitches. High current […]
Not a battery, not a cap: Murata’s small energy [storage] device
https://www.electronics-lab.com/not-a-battery-not-a-cap-muratas-small-energy-storage-device/
by Graham Prophet @ edn-europe.com: To meet what the company sees as a gap in the available range of energy storage solutions, Murata has developed the UMAC, a small, high-capacity cylinder-type energy device for use in wearable and wireless sensor applications. Although lithium-ion based, Murata differentiates it from a battery. The UMAC is a miniature device […]
Energy Wristband monitors energy usage on home
https://www.electronics-lab.com/energy-wristband-monitors-energy-usage-on-home/
by Matt Venn: A wristband that tells you energy changes in your home. It connects via a Raspberry Pi computer to a base station like a ‘current cost’ or similar. When a change in energy usage occurs, the wristband vibrates and a small LED bargraph shows your current usage from 1 to 4. Energy Wristband monitors […]
