PROGRAMMING AND SOFTWARE What i have planned my approach is like; Take image or snaps after ever n seconds, where n is an integer. Process the image. Divide it into regions , such as 1row X 3 column. Convert each region via histogram method. Correlate the region with pre-stored image samples. Stored the result and its actual time in excel sheet. INFRARED(IR) TRANSMITTER(TX) AND RECEIVER(RX) : IR pair is an electronic device which consists of two parts i) Transmitter and ii) Receiver. Transmitter is used to transmits or emit the INFRARED rays and the receiver is used simply to receive these radiations . Sounds simple and easy :). Transmitter is often known as IR LED and the Receiver as IR Sensor. How To distinguish Between CONTROL AND AUTOMATION VFD is a type of ASD (adjustable speed drives) that is used to control AC motors.AC motors can be of synchronous or asynchronous type, depending upon the use.However, asynchronous () motors due to there cheap cost are most widely used.Whether, the motor is synchronous or asynchronous, the working principles of VFDs remain valid for bothscenarios.

PRESSURE MEASUREMENT Digital gauges use an electronic pressure sensor to measure the pressure and then transmit it to digital display readout.. Calibration: This involves the following basic steps: Apply a set of mid-scale (pre-measured value) pressures to the gauge. Observe the readings. Depending upon the pointer indication, mark the values onthe scale.
UNPACKING THE BOX
To set up the raspberry pi follow this official procedure (link). Tip: Q: I followed; all the steps of the document but during NOOBS installation the available size of the memory card appears to be zero. Why? The actual size available is greater than 2Gb.

PRESSURE GAUGE:
A device which is used for pressure measurements. Pressure Gauge Operating Principle: Most standard dial type Pressure Gauges uses a Bourdon Tube- sensing element made of copper alloy brass or steel for measuring pressure 15PSI or above. The operation is simple and rugged and does not require any external power source. On the application of4D SEISMIC SENSOR
4D refers to fourth dimension, and it is an abstract concept in a mathematical analysis. 4D is a behavioral characteristic obtained by adding time-lapse to the well-known length, breadth and height 3D dimensions in space. In case of seismic monitoring system, 4D generates real-time images of repeated seismic surveys of an actualhydrocarbon or

INFRARED(IR) TRANSMITTER(TX) AND RECEIVER(RX) : IR pair is an electronic device which consists of two parts i) Transmitter and ii) Receiver. Transmitter is used to transmits or emit the INFRARED rays and the receiver is used simply to receive these radiations . Sounds simple and easy :). Transmitter is often known as IR LEDand the Receiver
as IR Sensor.
HOW TO DISTINGUISH BETWEEN THESE TWO ? * Connect cathode of one LED to +ve terminal of DMM * Connect anode of the same LED to common terminal of DMM (means connect LED such that It gets reverse biasedby DMM )
* Set DMM to measure resistance upto 2M Ohm. * Check the reading. * Repeat above procedure with second LED. * In above process, when you get the reading of the few hundred Kilo Ohms on DMM, then it indicated that LED that you are testing is IRsensor . In case of
IR transmitter DMM will not show any reading. SIMPLE TESTING CIRCUIT: Make connections as shown in the schematic below. IR pair Test Circuit The pair should face each other in an Head to Head manner and thedistance b/w these
should be as minimum as possible , but please make sure that there should be a small clearance b/w pair. OBSERVE THE FOLLOWING: * When there is no obstacle b/w the two the RED LED will startglowing.
* When there is an obstacle b/w the two the RED LED will stopglowing.
CONCLUSION:
* In the case , when the Infrared is reaching the receiver (Rx), the Rx would show the minimum resistance, ideally it could be Zero Ohms (or Short Circuit ). * In the case , when there is an Opaque obstacle (say Black Plastic Piece or the faces of the Pair are rotated) b/w the two , and the Infrared is not reaching the receiver (Rx), the Rx would show the maximum resistance, in the range of few Mega Ohms , Ideally could be Infinite Resistance (or Open Circuit).SHARE THIS:

Thankful for Your this information I would talk about a little something , How if The detector through launching the Electromagnetic ir and its not detect object what can I do , what is the solutions forthe black objects

Mr. Ahmed: take Rx as a transistor (BJT-Npn) when light falls on its head (base) transistor gets short circuit; else it is open circuit. So if you want to detect dark/black objects use common emitter configuration for RX; If you need more help; I can provide you schematic.Reply
