Smart Garbage Monitoring System Using SMART GARBAGE MONITORING SYSTEM USING IOT Y.Himanth1, B.V.Pavan Kumar2, M.Lalitha Bhavani 3 1,2,3Asst.Professor, ECE Department, SASI Institute of Technology & Engineering, Tadepalligudem, India Abstract Helps in maintaining the surrounding of In the recent years, there was a rapid growth dustbins clean. in population which leads to more waste The statistics can be used to estimate area disposal. So, a proper waste management wise quantity of waste which in turn used system is necessary to avoid spreading some to rank areas. deadly diseases. But due to lack of resources, In our system, the Smart dust bins are ineffective groundwork, some waste is not connected to the internet to get the real time collected which poses serious health hazard to information of the smart dustbins. These the surrounding environment. The dustbins are interfaced with Arduino based government of India announced smart cities system with ultrasonic sensors and weight and the key to smart cities is cleanliness. In sensors and Node MCU. Where the ultrasonic support of clean city we design a dustbin sensor detects the level of the dust in dustbin and which can interact with the cloud (free cloud sends the signals to Node MCU the same signal for demonstration) and push its filling percent is encoded and send to the application and it is at regular intervals (say every 1 hour or its received. The data has been received, analyzed status set to full). If the status of the dustbin is and processed in the database, which displays the filled, a message is pushed to the municipal status of the Garbage in the dustbin on the person who is responsible to empty the bin. application of authorized person system through The filling percent monitored by weight web application. The concerned authority get sensor and ultrasonic sensor continuously. alert about dustbin is full and informs person The status of the bin set to full when either the whoever is responsible for collecting garbage threshold weight reached (may be some space from the particular areas. The garbage trucks available in the bin) or it is filled up to a collect the garbage from the completely full threshold level (may be the weight less than dustbin and dispose. the threshold) and by using analysis of statistics to estimate area wise quantity of II METHODOLOGY waste which in turn used to rank areas which The whole proposal contains the following helpful in cities clean. modules INDEX TERMS: Internet of things (IOT) Collecting data from sensors.

The idea behind Google assistant-controlled Home automation is to control home devices with voice. On the market there are many devices available to do that, but making our own is awesome. In this project, the Google assistant requires voice commands. Adafruit account which is a cloud based free IoT web server used to create virtual switches, is linking to IFTTT website abbreviated as “If This Than That” which is used to create if else conditional statements. The voice commands for Google assistant have been added through IFTTT website. In this home automation, as the user gives commands to the Google assistant, Home appliances like Bulb, Fan and Motor etc., can be controlled accordingly. The commands given through the Google assistant are decoded and then sent to the microcontroller, the microcontroller in turn control the relays connected to it. The device connected to the respective relay can be turned ON or OFF as per the users request to the Google Assistant.

Home automation or domoticz a term for home automation coined by Jim Hill has been evolving drastically. We saw many home automation technologies introduced over these years from Zigbee automation to Amazon Echo, Google Home and Home from Apple. It has become a craze these days. Google Home price is around 150$ (USD) with an additional cost of the devices to be connected to, the total cost of the system reaches over 250$ (USD). Apple Home Kit too is pretty more expensive, over 100$ (USD) more than the Google Home just for a basic setup. Philips Hue, a smart light which is controlled by the Google Assistant, Amazon Echo and Siri, voice assistant by Apple is priced around 145$ (USD). Similarly, Belikin’s Wemo light is priced around 44$ (USD) per unit and this can be controlled both by Siri and Google Assistant. So, overall we can see here that to make our home smart we need to invest quite a lot, let’s say some 250$ (USD) for a basic setup.

The raw heart-rate signals were collected from finger using IR TX-RX (Infrared Transmitter and Receiver pair) module which was amplified in order to convert them to an observable scale. Extending the concept we have replaced Arduino board with NODE MCU. In this extension we have used Thing Speak and created a private channel. In that channel updating of heart rate at regular intervals is done. If it crosses a particular limit or threshold limit it will be send to a concern doctor. This technique can be used in remote areas. The results obtained using the developed device when compared to those obtained from the manual test involving counting of heart rate was found satisfactory. The proposed system is applicable for family, hospital, clinic, community medical treatment, sports healthcare and other medical purposes. Index Terms – NodeMCU, Thing speak, Pulse Sensor I. INTRODUCTION Heart rate data can be really useful whether you’re designing an exercise routine, studying your activity or anxiety levels or just want your shirt to blink with your heart beat. Monitoring heart rate is very important for athletes, patients as it determines the condition of the heart (just heart rate).

RINESH, 1 UG Scholar, 2 Assistant Professor, 1,2 Computer Science and Engineering, Saveetha School of Engineering, Saveetha Institute of Medical and Technical Sciences, Chennai, India 1 venkatesh.gupta17@gmailcom, [email protected]. Abstract- Earthquake early-warning systems detect the first quivering of a major quake, triggering alarm systems in advance of the most violent shaking. The Alert system that has been proposed for all over the world would use a network of digital seismometers deployed around the state to give populated areas up to a minute of advance warning (depending on the location of the epicentre). The alerts would allow businesses, residents and public agencies time to get ready. The purpose of the study focuses on the sensor data to decide if an earthquake is occurring. Finally experimental results are provided showing that the system will support the expected performance with the sensor data. A possible extension of the approach could be implementing one wireless sensor networks using thinkspeak for data acquisition. Keywords: THINGSPEAK, BOLT-IoT Platform, sensor, microcontroller,rectifier. INTRODUCTION When a natural disaster, such as a big individual sensing SPs capabilities. Although an earthquake, happens, we should first grasp the range and earthquake is totally unpredictable, this research presents sinuousness of the damaged areas for supporting the a real-time and economic countermeasure to this natural rescue activities.
