This work is on a machine overheat detection with alert. This project is used to detect the temperature of the devices which are overheated. This project is very useful in the industries or factories which have many big machines where the action must have taken place when the machines are overheated. In this system we use the digital sensor of temperature which is used to detect the temperature and after detecting the temperature it sends the signals towards the comparactor which are attached in this project. The comparactor which are attached in this ,computes on the data and then transfer the temperature reading and then this reading is displayed via LED. In this project we can use the 5 volts power supply which is used to supply the power to the system. In this system we can set the specific temperature of the machine. If the temperature exceeds the given value which is given to it, the temperature sensor sends signals towards the comparactor and then comparactor shows message or we use the buzzer in this system which produces the beep sound on exceeding the specific value of temperature which is given to the system

.1.1                                  BACKGROUND OF THE PROJECT

Modern manufacturing operations and other operating devices use many types of equipment that are subjected to loads that cause heating in portions of the particular machine or unit. Sometimes the heating occurs in electrically powered equipment, such as electric motors, welding transformers, and welding guns. The heating may also occur in equipment such as gear boxes and machining equipment that experience frictional loading. Often the equipment is used in circumstances that make maximum use of its design capabilities and may result in substantial heat generation within a particular heavily loaded, manufacturing unit. Further, the equipment may be expected to operate with minimal operator attention or oversight.Thus, there is a need for inexpensive and low energy-consuming devices that may be adapted to function autonomously as a temperature monitor, providing an overheat signal or over-temperature signal, for the particular environment of many different machines used in manufacturing or other operations. There is a need for such devices to fit, non-obtrusively, on or in thermal contact with the equipment, or within the equipment, and to give a visible warning signal if, or when, some portion of the equipment reaches a temperature that indicates that it is overheating, which is likely to be harmful to its continued operation.This invention provides devices that are adapted for placement on (or in thermal contact with) a surface of an operating unit of equipment, machine, or the like, for the purpose of raising a visible, tabular, warning flag when the operating machine unit is experiencing overheating. The up-standing warning flag is sized and located to inform nearby operating personnel that the operating unit is in danger of being damaged by its overheated condition.Each such in-situ, overheating-detection device is shaped, or otherwise adapted, to be placed on a selected surface of the equipment, often a surface that is visible to someone in the vicinity of the equipment as it is being operated. The selected surface region of the equipment unit will serve as a useful sensing location if the unit experiences an overheating condition of operation. During operation of the equipment, heat will be transferred from the selected surface of the unit into a special material portion of the in-situ device. The special material is sometimes referred to in this specification as an “active” material or as a “smart” material. The material is characterized as active or smart because it is composed or adapted to experience a physical transformation when it is heated to a temperature range indicative of overheating in the equipment on which it is placed or in intimate thermal contact. This transformation of the active material is used to raise (or otherwise re-position) the tabular flag member to a position in which it is visible, or may otherwise give its notice of machine overheating.As will be more fully described in this specification, examples of suitable active materials include linear shapes of shape memory alloy compositions, sheets or other suitable shapes of shape memory polymers or other polymer compositions, and certain confined volumes or bodies of organic paraffin materials. As stated, the active material is selected, composed, or otherwise adapted to experience a useful physical transformation when it is heated by its contacting equipment unit to a temperature, or narrow temperature range, indicative of overheating within the machine that it serves. Often such a temperature may be in the range of about 70° C. to about 100° C. and higher. The active material will lie inactive, in suitable close heat transfer relationship with the equipment surface, during normal temperature operation of the equipment. But when the active material is heated to a temperature, indicative of overheating of the equipment, the active material will transform in its composition and shape so as to serve as an actuator of a warning flag, stored on the subject in-situ device. The actuated flag or tab will be moved (sometimes simply rotated) to a position away from the surface of the overheated equipment so as to give appropriate notice of the sudden and potentially damaging, over-temperature condition of the equipment unit.In many embodiments of the invention, an in-situ device will comprise an over-temperature, alarm-giving, tabular flag and a suitable body of active material for sensing an over-temperature condition of a unit of manufacturing equipment. The flag tab is suitably formed of metal, polymer, wood, or other solid material and may often have a generally flat rectangular shape. It may be brightly colored or coated to more-readily present its alarm-giving message. The flag member is usually stored in a concealed position near the surface of the equipment that the in-situ warning device is serving. In many embodiments of the invention, the flag is held in its stored condition against the force of a coiled spring, capable, upon a release, of quickly rotating the flag about one of its ends into its over-temperature, notice-giving position. When the active material is heated above its selected transformation temperature, the material changes shape in a manner that triggers the spring to move the flag from its stored position to its notice-giving or alarm-giving position. The flag may be brightly colored so as to be readily visible, and to give prompt notice to a worker in the vicinity of the over-heated machine, so that it may be shut down or its work-load reduced. In some embodiments of the invention, the movement of the flag to its notice-giving position may also be used to initiate an audible signal, or a more widely visible bright-light signal, of the over-temperature condition of the manufacturing unit. In other embodiments, the relocated flag may also close a circuit to initiate an electronic signal to a computer or other device for recording the over-temperature event or for a computer-initiated change in the loading or operation of the equipment unit or associated equipment.It will be appreciated that the respective components of the in-situ over-temperature device may be contained within a suitable housing for maintaining the working relationship of the active material, spring(s), flag tab(s), and other components of the subject device. The overall shape of the device is managed to enable it to fit the active material in suitable heat transfer contact with a surface of the equipment to be protected or in a position nearby the equipment in a suitable heat transfer relationship with the equipment. The device may also be constructed for re-setting of the flag-member to its stored position after the device has cooled from an overheat condition.

1.2                                        OBJECTIVE OF THE PROJECT

The objective of this work is to design a device such as is used, for example, in manufacturing operations, each fitted-device serving to give notice of overheating of the machine to which it is attached or thermally connected The release of the visible overheat sign can be further used to initiate an audible warning signal, and can also initiate a signal for preserving a record of the overheating event.

1.3                               SIGNIFICANCE OF THE PROJECT
