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

when translated into English means "seize the day." Themes of "carpe diem" were predominant in seventeenth century poetry‚ and this can be seen in the two poems‚ "To the Virgins‚ to Make Much of Time‚" by Robert Herrick and "To His Coy Mistress" by Andrew Marvell. Robert Herrick’s‚ "To the Virgins‚ to Make Much of Time" is a popular poem in British literature‚ that professes a common universal moral. The first two lines read‚ "Gather ye rosebuds while ye may‚ Old time is still a-flying." Herrick wrote

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

How Ultrasonic proximity sensor works An ultrasonic proximity sensor uses a piezoelectric transducer to send and detect sound waves. Transducer generate high frequency sound waves and evaluate the echo by the detector which is received back after reflecting off the target. Sensors calculate the time interval between sending the signal and receiving the echo to determine the distance to the target. When the target enters the operating range the output switches. The ultrasonic proximity switches are

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
