greenhouse climate conditions in a preprogrammed manner. The proposed system consists of three stations: Sensor Station‚ Coordinator Station‚ and Central Station. To allow for better monitoring of the climate condition in the greenhouse‚ the sensor station is equipped with several sensor elements such as CO2‚ Temperature‚ humidity‚ light‚ soil moisture and soil temperature. The communication between the sensor station and the coordinator station is achieved via ZigBee wireless modules and the communication

KEYPAD & SENSOR IN PIC MICROCONTROLLER. A 4X4 matrix keypad is useful for the function like a simple calculator or telephone. The 4X4 keypad has 16 keys which are arranged in push button switches in rows and columns. This keypad is followed by two other components‚ the 16-key encoder and the sensor pad. As you can see below is the diagram on a simple 4X4 matrix keypad. This requires users to key in numbers in decimals or hexadecimals depending on the encoder that is programmed to the 4X4

detection is the process of identifying potentially hazardous gas leaks by means of various sensors. These sensors usually employ an audible alarm to alert people when a dangerous gas has been detected. Common sensors used today include Infrared Point Sensor‚ Ultrasonic gas detectors‚ electrochemical gas detectors‚ and Semiconductor Sensors. More recently‚ infrared imaging sensors have come into use. All of these sensors are used for a wide range of applications‚ and can be found in industrial plants‚ refineries

IEEE SENSORS JOURNAL‚ VOL. 6‚ NO. 3‚ JUNE 2006 631 Magnetic Sensors and Their Applications James Lenz and Alan S. Edelstein Abstract—Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics. Here‚ we describe and compare most of the common technologies used for magnetic field sensing. These include

Instead‚ panelists linked cheating to the social pressure put on students to prize high grades over education and other values‚ including creativity and imagination. Pressure by parents and schools to achieve top scores has created stress levels among students—beginning as early as elementary school—that are so high that some educators regard it as a health epidemic

In this assignment‚ we are assign to construct a 2 button type Ac motor control system. The 2 type button means that there are only 2 buttons which is the stop button and the forward button. The successful build the whole system‚ a few component are very critical in this system. Circuit breaker First is the circuit breaker. Circuit breaker is a switch which is designed to prevent damaging the circuit when there is over load or short circuit. But the circuit breaker works differently compare

Pressure Today in our modern society cheating in school is growing at a rapid rate‚ but who is to blame‚ is it the school system is it students or is it the teachers. I strongly believe that it is not only the student’s fault but the school systems as well. To begin‚ cheating among students has rapidly increased. The numbers are crazy; statically 2 out of every 3 kids have cheated on a test‚ homework‚ ect. “Cheating in school is rampant and getting worse 64% of students cheated on a test in the
