Three
Phase Electrical Energy Metering System: |
| |
Hardware and Software
design of device, built around AT89C55WD,
uses an energy meter chip to measure
power, voltage and frequency with
the help of high speed microcontroller
to perform necessary calculations
to obtain actual meter readings.

Data
Logger: |
| |
The microcontroller
based (AT89C55/AT89C2051) data logger
for recording analog signal. The DataLogger
provides two 8-channel analog input
(-99mV to +999mV), 1-channel pulse
input, battery backup 256kB SRAM,
Real-time clock, and RS232. Start/Stop
recording can be made by MANUAL switch
or preprogrammed Start/Stop Time.
The format of uploading data is ASCII
format, suitable for importing and
graphing by Excel or any Scientific
Plot Program. Exemplary circuit used
for measuring Insolation and Air Temperature
vs. Time is included.

PID-Motor
Controller: |
| |
Hardware and Software
design of device, built around PIC16F876,
allocating the processing power to
keep track of pulses and actively
control the motor with PID action.

|
|
Programmable
Sensing & Control Unit (RS485-ModBus
Protocol): |
| |
Hardware
and Software design of a device, built
around AT89S52, for practical position
control over motors. There is no need
to buy additional handheld programmer
and machine easily connects with Programmable
Logic Controllers (PLC). It produces
upto 20K pulses per second, has 30 commands
and can store one or 10 sets of motion
programs. Upto 16-slave controllers
can be connected using PLC as the master
control. |

Data
Downloader: |
| |
Hardware and software
design of unit, built around AT89C2051,
to download data from multiple logger
or serial devices like weighing scale
remotely. The data is stored in internal
memory, which can be uploaded to PC;
the no. of records to store in the
unit is restricted only by the size
of each record.
The microcontroller based data downloader
has an RS232 communication port for
uploading data from various field
devices or logger & downloading
into PC.
