Beam of invisible pulsed modulated infra - red light is produced by emitter. This beam is sensed by receiver at another end (in through beam version) or reflected by object and received by receiver placed near emitter (in diffuse version). When this beam is interrupted by object, the receiver signal gets changed and signal is produced.

This is a plug and play GSM Modem with a simple to interface serial interface. Use it to send SMS, make and receive calls, and do other GSM operations by controlling it through simple AT commands from micro controllers and computers. It uses the highly popular SIM300 module for all its operations. It comes with a standard RS232 interface which can be used to easily interface the modem to micro controllers and computers. The modem consists of all the required external circuitry required to start experimenting with the SIM300 module like the power regulation, external antenna, SIM Holder, etc. Features Uses the extremely popular SIM300 GSM module Provides the industry standard serial RS232 interface for easy connection to computers and other devices Provides serial TTL interface for easy and direct interface to microcontrollers Power, RING and Network LEDs for easy debugging Onboard 3V Lithium Battery holder with appropriate circuitry for providing backup for the modules’ internal RTC Can be used for GSM based Voice communications, Data/Fax, SMS,GPRS and TCP/IP stack Can be controlled through standard AT commands Module’s operation mode can be controlled through the PWR Switch connected to the PWR pin (refer the SIM300 datasheet for more information) Comes with an onboard wire antenna for better reception. Board provides an option for adding an external antenna through an SMA connector The SIM300 allows an adjustable serial baud rate from 1200 to 115200 bps (9600 default) Modem a low power consumption of 0.25 A during normal operations and around 1 A during transmission Operating Voltage: 7 – 15V AC or DC (board has onboard rectifier) Note: The modem consumes current of nearly 1A during transmission; please make sure that your power supply can handle such currents.

The unit is a port powered two-channel (half-duplex) RS-485 to RS-232 converter. It converts the balanced halfduplex RS-485 signals to TD and RD RS-232 lines. The unit is powered from the RS-232 data and handshake lines whether the lines are high or low. An external power supply can be connected to two terminals on the RS-485 connector if no handshake lines are available. Although the converter uses handshake lines to power itself, no handshaking is required to control the RS-485 driver. The RS-485 driver is automatically enabled during each spacing state on the RS-232 side. During the marking or idle state, the RS-485 driver is disabled and the data lines are held in the marking state by the 4.7k ohm pull-up and pull-down resistors. The value of these resistors may need to be changed to a different value when termination is used in order to maintain the proper DC bias during the idle state.

IntroductionThe Optical Proximity Switches are a reliable solution for automation where other Proximity Switches have limitations.These are Infra-red type sensors incorporating advance and reliable technology.These switches have a distinct advantage of higher sensing distance over Inductive and capacitive type switches.   These can work more reliably in a noisy electro-magnatic radiation environment. As an infra-red wavelength is used, it is immune to visible light interference.Applications These switches are very useful for counting and position sensing application in Pharma, food, Paper, Plastic Automobile industry. They also work effectively in level sensing applications for solids, grains, sand, ice and other non-metallic bulk material. Some typical applications are; Component positioning sensing in Electronic Industry Counting of bottles, Jars, Containers etc. Glass sheet position sensing For security 7 safety in machine Tools, presses etc. Colour sensing applications Principal Of OperationThese Switches incorporates an infra-red transmitter and receiver device hose in single enclosure or separate enclosure. The precision pulsed transmitter beam is interrupted or reflected by the object. The advanced electronic circuit generates an effective output signal when the object is sensed.Diffused Scan: Diffused scan type switches have both transmitter and receiver is same enclosure. The closely focused beam is reflected back by the object. Through-Beam: Through-Beam type switches have separate transmitter and receiver. The object is sensed when the beam is interrupted.Retro Reflective: Retro reflective switches use a special reflectorto reflect back the beam. When an object interrupt the beam, an output signal is generated. These model have greater sensing distance compare to diffuse scan type. The receiver does not considerthe reflection from the object.Technical Terms Standard ObjectThe sensing distance specified for diffused scan switch is considered with a white object having minimum 90% reflectivity.ConstrictionThese switches are offered in tubular metallic, Acrylic and Plastic enclosure. Standard model are available with integrated two meter long cable. Switches with built in (Male) connector.
