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

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

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
