Vensoft Technologies is a Electronic Design Services (EDS) for VLSI / EMBEDDED and MATLAB, delivering a wide variety of end- to -end services, including design, development, & testing for customers around the world. With proven expertise across multiple domains such as Consumer Electronics Market, Infotainment, Office Automation, Mobility and Equipment Controls.
Vensoft Technologies is managed by Engineers / Professionals possessing significant industrial experience across various application domains and engineering horizontals.Our engineers have expertise across a wide range of technologies, to the engineering efforts of our clients. Leveraging standards based components and investments in dedicated test lab infrastructure, we offer innovative, flexible and cost-effective services and solutions.
“We are sure you don’t want to say “This is what I said but not the one I want” when we deliver. So before we start any custom application development project, we always ask our client to define scope of the project. Without having defined scope, you will not be able to measure whether we have satisfied your requirements. It does not mean that it is your duty to give us defined scope. We are here to help you with that. Our experts will be in touch with you during this phase and prepare requirement spects and get it signed from you once you are happy with the same.”

Security Integrated system based on wireless
access protocol for industrial applications with
SMS alert system using GSM modem.
Abstract:
Security is primary concern for everyone. This Project describes a design of
effective security alarm system that can monitor an industry with eight different
sensors. Unauthorized access, Fire accident, wall braking, IR detection, and fire
detection can be monitored by the status of each individual sensor and is indicated
with an LED. This LED shows whether the sensor has been activated and whether
the wiring to the sensor is in order. Obviously, this burglar alarm also has an input
to 'arm' the alarm, a tamper input and a couple of outputs to control a siren and
Auto dialing system.
The alarm is also fitted with a so-called 'panic button'.
The burglar alarm is built around the Atmel micro controller from Atmel. This
micro controller provides all the functionality of the burglar alarm. It also takes
care of filtering of the signals at the inputs. Only after an input has remained
unchanged for 30 milliseconds, is this new signal level passed on for processing by
the micro controller program. This time can be varied by adopting small changes in
the source code. A maximum of 8 sensors can be connected to the burglar alarm.
These sensors need to have their contacts closed when in the inactive state (i.e.
Normally Closed). In addition, each sensor needs to have its tamper connection
wired as well. A power supply voltage of +5 VDC is available for each sensor at
the corresponding wiring terminals. Eight LEDs indicate the status of the
corresponding sensors. When the alarm has been activated, the LED of the sensor
that caused the alarm will light up, or flash in the event of a cable failure.
When the alarm is armed, the LED 'alarm armed' will flash during the exit-delay.
After the exit-delay, the LED will light continuously. The LED 'alarm triggered
LED' flashes during the entry-delay and will turn on continuously once an actual
alarm has been generated. 'Alarm triggered LED’ turns off only when the alarm is
switched off with key switch Sw1. When an alarm has taken place, it can be
determined afterwards which sensor (or tamper input) caused the alarm to trigger.
