Smart Light City & UG Cable Temperature Monitoring System

STORY/PROBLEM

As it was stated earlier, it is seen in a number of cities that the street light is one of the huge expenses in a city. The cost spent is huge that all the sodium vapor lamps consume more power. The expense spent on the street light can be used for other development of the nation. Currently a manual system is used where the light will be made to switched ON/OFF i.e. the light will be made to switch ON in the evening and switched OFF in the morning. Hence there is a lot of wastage of energy between the ON/OFF. This is one of the major causes of shifting to the automatic system, since there is less wastage of power and thus saving a lot of monetary expenses. Apart from this, the other disadvantages of the existing system are described below.

Underground power transmission cables often have to face the challenge of poor ventilation, which decreases power transmission capacity and damages the materials of the cable in a high temperature environment. It is necessary to take a heat dissipation measure to ensure not only the safety but the efficiency of power transmission systems.

PRESENT WORK/ METHODOLOGY

In this project Bolt IoT module is used for the controlling the light system and the temperature monitoring of the underground cables. To make the easy and convenient process of using the Bolt IoT module, the Bolt provided their own application, own cloud interface, own Devices for the user. The application name as “Bolt IoT App”, the cloud named “https://cloud.boltiot.com” and the devices names as “Bolt Wi-Fi Module”. The maximum 5v supply is given to the Bolt module. The circuit is made connected as per the connection method and the device is connected to the Bolt Cloud through internet using the interfacing devices which in Android or IOS Mobile. Through the Cloud the required program and instructions will be inserted to the Bolt Wi-Fi Module device, then the device works as per the requirement, without any physical connections between the Cloud and the Device.

Light Controlling project is connecting the light system to the Bolt Cloud using the Bolt IoT module. In the Bolt Cloud, through user interface we are operating the ON/OFF system of the light. The respected HTML program will be inserted to the Bolt Wifi Module from the cloud interface to control the ON/OFF condition of the light. The Python program will interface to the Bolt device through the Linux Ubuntu 16.04 Terminal box, which sends the alert massage to the user about the live condition of the device. As per the algorithms given in the program the device works or talk with the Bolt IoT Cloud. The user can control the light system from the Cloud interface and the Bolt App.

Temperature monitoring project is sensing the live temperature of the underground cables. The sensor LM 35 is used in this project for the live temperature sensing. The sensor is placed at the point where the underground cables are laid. The sensor is activated by the Bolt IoT wifi module, this module is interfaced to the Bolt cloud. The Java Script program is inserted to the Bolt Wifi Module through cloud interface to get the live temperature in Cloud interface. The Python program will interface to the Bolt device through the Linux Ubuntu 16.04 Terminal box, which sends the alert massage to the user whenever the temperature exceeds the minimum or maximum limit of the temperature which in set in the program. The user can monitor the live temperature on Cloud interface and at the Bolt App.

• Reduction of manpower

CONCLUSION AND FUTURE SCOPE

A design scheme for controlling a streetlight based on Bolt Wi-Fi module has been demonstrated, which can be programmed to react to events (based on day and night detection) and to cause corresponding actions. The proposed scheme provided with the mode in which automated system is used to control the streetlights. i.e based on light intensity the sensor sends the data to bolt and it till take actions according to the algorithm

IoT based temperature and humidity detecting device provides an efficient and definitive system for monitoring agricultural parameters. The system also provides a corrective movement or decision-making system. IoT based monitoring of area is a handiest, but it also allows the consumers to research the correct modifications within the surroundings and for taking possible action. It is inexpensive and consumes much less electricity

IoT based system can be extended for controlling extraordinary electronic and electric devices from remote locations.
