Prepaid Energy Meter with GSM Modem using pic microcontroller

Prepaid Energy Meter with GSM Modem using pic microcontroller

In this tutorial will learn how to interface ADC0804(Analog to Digital Converter) with 8051(89c51,89c52) microcontroller. 8051 microcontrollers are pretty old and don’t have a build in analog to digital converter in them unlike their new rivals(Arduino, Pic microcontroller and many more). Hence we can not directly measure any analog value (voltage, Temperature present in the

RAK8213 – THE NEW MINI PCIE CARD FOR NB IOT AND LTE CAT M1

RAK8213 – The New Mini-PCIe Card For NB-IoT and LTE Cat M1

A China-based manufacturer called RAK Wireless has released the RAK833 LoRaWAN gateway module a couple months back. This has already been used hugely to create a gateway for ‘The Things Network’. Now they’re back with the new RAK8213, an NB-IoT and LTE Cat M1 module in the same mini-PCIe form factor as the RAK833. The RAK mini-PCIe card is constructed

TrH Meter A DIY indoor thermometer plus hygrometer with adaptive brightness control implemented to 7 segment LED displays

TrH Meter: A DIY indoor thermometer plus hygrometer with adaptive brightness control implemented to 7-segment LED displays

This project is about building a microcontroller-based digital room thermometer plus hygrometer that displays temperature and relative humidity on 4 large (1 inch) seven segment LED displays which adjust their brightness level according to the surrounding illumination. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor

Electricity Grid Frequency Meter

Electricity [Grid] Frequency Meter

An article by Dieter Laues in the February 2012 issue of Elektor inspired me to get my soldering iron out. The article described how by measuring the frequency of the mains electricity supply in any socket, the relative load across the entire electricity network could be determined. I ordered a pre-programmed processor (of the correct

Elektor 500ppm LCR meter case tips

Elektor 500ppm LCR meter case tips

I recently bought a 500ppm LCR meter from Elektor because I didn’t have anything for measuring inductors or the ESR (equivalent series resistance) of capacitors, both of which are important for modern electronics, particularly switch mode regulators that have become ubiquitous. It is also more accurate than any of my multimeters and has wider measurement

Internet of Things Power Meter

Internet-of-Things Power Meter

The Internet-of-Things Power Meter (IPM) is a device fixed on top of the regular household power meter that provides detailed information about the electricity usage. Modern power meters have a LED blinking every time a Watt is used, the IPM detects these flashes using a light sensor, counts them, saves the values to an SD
