Very Accurate LC Meter based on PIC16F628A

About Accurate LC Meter This is one of the most accurate and simplest LC inductance / capacitance Meters that one can find, yet one that you can easily build yourself. This LC Meter allows to measure incredibly small inductances starting from 10nH to 1000nH, 1uH to 1000uH, 1mH to 100mH and capacitance from 0.1pF up to 900nF. LC Meter's circuit uses an auto ranging system so that way you do not need to spend ...

Determine capacitance by measuring the charging time using PIC16F688

When TEST botton is pressed, RA3 pin is set to "1". R2 and R3 are divide the voltage to 1/2 Vra3 which is connected to RA2 pin to be a Vref for comparator. The C undertest is charging and the timer is start. When the voltage of C undertest is more than 1/2 or above Vref, the timer is stop. and a number of periods that elapsed multiply by 10 is the C value in nF. Convert C number to string and display to 1x1 ...

Tampered Energy Meter Monitoring Conveyed to Control Room by GSM with User Programmable Number Features

The main concept of this project is to reduce the power theft by using an integrated energy meter such that whenever an energy meter is tampered, it sends an alert message to the concerned authorities through the GSM modem for indicating power theft. Day by day  increase in the usage of electricity is leading to several attempts of tempering the energy meter by the masses. The routine way of identification ...
