SIM900A GSM/GPRS Module SIM900 is an ultra-compact and reliable wireless SMT (Surface Mount Technology) type quad-band GSM/GPRS module. It is very compact in size and easy to use as plug in GSM Modem. The Modem is designed with 3V3/5V TTL interfacing circuitry, which allows you to directly interface to 5V microcontrollers (PIC, Arduino, AVR etc) as well as 3V3 Microcontrollers (ARM, ARM Cortex XX, etc) .The baud rate can be configurable from9600-115200. AT commands are used to interface and control the GSM/GPRS module.  Features of SIM900A are as follows: RS 232/ Interface DB port Voice communication port On board voltage regulator Power/single LED indication SMA connector for antenna connection The sim900 offers GSM/GPRS900/1800/1900 MHz for voice, SMS, DATA, Fax Low cost Module can be easily interfaced with AT commands AT is the abbreviation of attention and AT commands are instructions used to control and interface the modem. Despite the fact that every command li

About arduino microcontroller

Image
ARDUINO Arduino is a platform for prototyping interactive objects using electronics. It consists of both hardware and software: a circuit board that can be purchased at low cost or assembled from freely-available plans; and an open-source development environment and library for writing code to control the board. Arduino comes from a philosophy of learning by doing and strives to make it easy to work directly with the medium of interactivity. It extends the principles of open source to the realm of hardware, supporting a community of people working with and extending the platform. It has been used in universities around the world and in numerous works of interactive art.  TYPES OF ARDUINO USED ARDUINO UNO The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everyth

Formwork disturbance detection

Image
Abstract— This research deals with  one of the common problems occur during the construction / life time of the structure i.e. failures of form work during the construction work of the structure due to the failure of the material ,external loads or by human error the placement of the formwork may displaced this may leads to structural failure of the building. Due this designed characteristics are May not achieved by the structure. Sometimes due to this reason building is demolished and reconstructed otherwise we have to go for external support by using steel supports at the end cost of construction is increases. In other hand, once structure constructed the settlement of the structure during life time of the building due to consolidation / structural failures.  It may leads to failure the building and also danger for the usage. These types of settlements are detected by settlement detecting device in initial stage itself so, that accidents due to collapse of the building is avoi
