went above the red spectrum‚ a color not visible to the human eye‚ that the temperature increased. This led to the discovery of infrared light. (“History of infrared”‚ n.d.‚ para 1) 1801 – Jumping on the coat tails of Herschell’s groundbreaking discoveries‚ a year later Johann Wilhelm Ritter‚ a polish born physicist‚ hypothesized that light might exist past the infrared spectrum. Ritter discovered that if he used silver chloride‚ and the same glass prism‚ that an intense reaction would occur in

CAUSES OF GLOBAL WARMING: a) The Greenhouse Effect- The term “Greenhouse Effect” refers to the process by which absorption and emission of infrared radiation atmosphere gases (mainly Greenhouse gases such as CO‚ NO‚ and Carbon Monoxide) warms the Earth’s atmosphere and surface. b) Solar Variations- Solar variations are changes in the amount of radiant energy emitted by the Sun. It is

INTRODUCTION In a country like india agriculture is a majour source of income still today a majourity of the population is living in the rural areas and depending on the agriculture for their earnings. This pattern has been followed for many years and people work on their basic instrument depending fully on the mercy of weather. And today to ADD TO THEIR VOWS THE EM WAYS BEING EMMITED FROM THE CELL TOWERS ERRECTED FOR MORDANIZATION IS MAKING THEIR EFFERTS useless. The impact is not visible

today’s technology world. The four kinds of cordless technologies I would prefer to speak about will be IR or Infrared‚ satellite signals‚ microwave signals‚ as well as radio systems. These kinds of systems transmit data in various ways and strengths. All of these types of systems have their advantages and disadvantages. Infrared is dependent on the utilization of infrared light signals. Infrared light isn’t noticeable by the human eye. This kind of signal utilized LEDs and ILDs to transmit signals as

------------------------------------------------- Etymology The word horticulture is modeled after agriculture‚ and comes from the Latin hortus "garden" and cultūra "cultivation"‚ from cultus‚ the perfect passive participle of the verb colō "I cultivate".Hortus is cognate with the native English word yard (in the meaning of land associated with a building) and also the borrowed word garden. ------------------------------------------------- Understanding horticulture Horticulture is a term

ii) Remote control For ensuring the safety of the user this system provides an additional type of controlling other than BRI and it is Remote control‚ which means robot is controlled by an external person. The switching of the control system is optional which is done by a mode selector. Simplified block diagram of remote control is shown in Fig.5. Atmel microcontroller is used in the design process of remote control. These types of microcontroller provide justified technology‚ an affluent efficiency

the IR beam gets interrupted when someone is standing at the gate or passing through it. The transmitter circuit (see Fig. 1) is built around timer NE555 (IC1)‚ which is wired as an astable multivibrator producing a frequency of about 38 kHz. The infrared (IR) beam is transmitted through IR LED1. The receiver circuit is shown in Fig. 2. It comprises IR sensor TSOP1738 (IR RX1)‚ npn transistor BC548 (T1)‚ timer NE555 (IC2) and some resistors and capacitors. IC2 is wired as a monostable multivibrator
