A Green-Light smart switch is an electronic circuit that automates the lighting of a room based on the level of ambient light. The switch is activated when the room is dark, turning on the light, and deactivated when there is sufficient light, turning off the light. The switch is built using commonly available electronic components such as an LDR (Light Dependent Resistor), a transistor, a relay, a diode, and a resistor. Features: The Green-Light smart switch is user-friendly and easy to operate. It is designed to save energy by automatically turning off the light when there is enough light in the room, and turning it on only when it’s dark. In addition to this, it also has the following features 1. High Accuracy: The circuit is designed to be highly accurate in detecting ambient light levels. The LDR used in the circuit is sensitive to light and can detect even the slightest changes in light intensity. 2. Cost-effective: The circuit is built using commonly available electronic components, which makes it a cost-effective solution for automating the lighting of a room. 3. Low Power Consumption: The circuit consumes very little power, making it an energy-efficient solution for automating the lighting of a room. 4. Automatic shut-off: The circuit turns off the lights automatically when there is sufficient ambient light in the room resulting in saving the cost of electricity. Functionality: The Green-Light smart switch works by using the LDR as a light sensor. When the room is dark, the resistance of the LDR is high, which causes the transistor to turn on. This, in turn, energizes the relay, which switches on the AC bulb. When there is enough light in the room, the resistance of the LDR decreases, causing the transistor to turn off. This de-energizes the relay, which turns off the AC bulb. Conclusion: The Green-Light smart switch is a simple and effective solution to automate the lighting of a room. The switch is easy to install, user-friendly, and customizable. It can help save energy and reduce electricity bills by automatically turning off the light when it’s not needed. The switch can be built using commonly available electronic components, making it accessible to everyone.

Monitoring water quality provides empirical evidence to support decision making on health and environmental issues. Monitoring water quality in 21st century is a growing challenge because of the large number of chemicals used in our daily lives and in commerce that can make their way into our waters. Govt. innovation lab (GIL) has worked on a pilot project of automation of WQM to make service delivery efficient for the end user and monitoring of filtration plants easy to PHE. As there is no existing automated system to monitor water quality of more than 700 PHE water filtration plants. The water quality includes its TDS, PH, Turbidity, Temperature & Water Flow. Currently this all is done manually whenever needed which is costly & time consuming. The purpose of this system is to provide PHE with a hardware + software based product having a water quality monitoring kit & web+ App dashboard, which facilitate them to administrate & automatically monitor filtration plant for water quality any time & get all the details anywhere through dashboard. Besides this, any citizen can also get the plant details using android app & subscribe to any plant or nearby plants to get its information notifications. A citizen can also submit a complain through app to Admin when needed. Whereas any PHE admin/ Executive can check those complains on dashboard, resolve them, add devices, change settings of dashboard & download information. All the functional & non-functional plants could be easily searched & seen over google map in dashboards with their detailed description. This system is totally tested in different environments & water resources which gave expected results & it completely terminates manual work of filtration plants & provides total ease to its users with accuracy in real time. Features • Live access, interaction and analyze up-to date information of water quality and daily output • Enable smarter, data-driven decisions regarding maintenance requirements • Citizen feedback, complaint and scheduling alerts • Cloud based with Android app and Dashboards

Environmental problems are raised by modern cities for waste collection and disposal. Therefore, smart waste management systems became essential for cities that aim to reduce cost and manage resources and time. Currently, the trend is shifting towards smart devices and internet of things (IoT) solutions to overcome common problems such as waste management issues. Optimizing the process of trash collection is the main purpose of the smart solutions provided by industry. However, the cost of applying such solutions is still relatively high. The purpose of this work is to present to provide clean environment, intelligent bin and a cost-effective smart trash bin for localized and small-scale cases, such as small parks, university campus, colonies and hospitals. We have introduced garbage waste management system called SMART BIN, working on IoT base. It has an external power battery which has long life. It will send message by itself to the driver as well as to the admin ‘’I am full, please unload me” and send an url of its location with the message. Driver will receive a message from Bin with exact location in Url. If driver not response to it, it will send the same message after 30 minutes until they response it. Whenever driver empty the Bin it will automatically send the message to admin and driver that “I have been cleared” and the record of all messages which sent by dustbin to both of admin and driver are save as a history on the dashboard. Through which can check the punctuation of driver. In a certain area only one Bin has a GSM module which can help out the other nearest bin through Bluetooth smart module which has around 1000m range. The other nearest Bin do the same process using the share gsm. It will show the red light on the top of Bin to the public to show I am full please don’t put more dust. After clearing it will off the light automatically. Features: • Public awareness about it fullness • Aware itself on the fullness • Automatically send message • Send location url by itself • Not be quit until not unload • Save history on dashboard • Long life external power • Communication with other bins
