Patrolling during the night is currently a primary responsibility for surveillance teams. There aren't many places where police can't be found keeping an eye on things. As a result, a robot that can detect trespassers is a requirement. The main purpose of this paper is to build a Patrolling Robot that follows a random path across the entire region. It monitors the premises using a night vision Wi-Fi camera and identifies intruder movements. The photographs are captured by the robot using a night vision Wi-Fi camera. These photographs are then relayed in real-time to the user, who will study them. Sound sensor for sound detection, PIR sensor for motion detection, Ultrasonic sensor for obstacle detection, and Accelerometer for fall detection are all included. It also offers live streaming video that may be recorded for future investigations and does not necessitate the presence of a human observer. Remote areas can be studied as part of this initiative, which can be employed in hospitals, industrial sites, military bases, and restricted zones among other places. [ABSTRACT FROM AUTHOR]

Automation is becoming the standard in today's society, and this will continue to be the case in agriculture. The advantage of mechanized agriculture is greater farmer comfort and development. Farmers frequently use weeds to control weeds in dryland areas. It is a very old approach that dates back to antiquity. These can be performed by manual labor such as hand removals or the use of tools. However, a larger number of individuals are typically involved in this job, and weed-removing diesel vehicles such as pullies or tractors are employed to pluck the weeds from the fields, making it more than simply a time-and money-consuming exercise. Weed removal from the ground is a risky practice. It causes back discomfort, dehydration, and skin issues. As a result, the entire procedure is quite unpleasant for everyone. As a result, a weed-cutting technology that works efficiently and effectively without human intervention is useful. Finally, to circumvent these issues, our suggested system uses IoT to give a flexible solution for weed cutting. The gadget was managed by a single person, but it may now be customized with modules, internet connectivity, and a mobile app. The smartphone app allows the user of the weed-cutting gadget to cut weeds in dry fields. This method is simple to set up and run in dry areas. Technical features of farmer-friendly robotic vehicles are discussed in this research. [ABSTRACT FROM AUTHOR]

Wireless networks are using an increasing amount of energy to assure the quality of service as the number of high-data-rate applications increases. As a result of inadequate energy resources and eco-friendly transmission, energy-efficient communications have received significant attention. Data transmission and energy usage are tightly related in wireless communication, whereas the channel's capacity limits the data rate, and It's currently unclear how much energy a communication system require in future generations. So, in this paper, transmission power p, bandwidth B are varied to find the maximum achievable limit on Energy efficiency in future wireless devices under different scenarios. Analysis of energy efficiency as a function of channel gain and bandwidth is performed in the simulation of a single antenna system. [ABSTRACT FROM AUTHOR]

Smart Exterior Home Management System is all about managing the exterior activities of a house automatically without the efforts of a human. This paper involves the smart managing of four different tasks that are executed outside of the house. To begin with, the first idea is about automating the water motor based on the water level present in the water tank. The motor automatically turns on and off by constantly checking the water level in the tank. The next idea is to give notifications to the house members when any posts or deliveries like newspaper, milk packet, letters, etc., are received in the carriage box arranged outside of the main gate. Coming to the next automation that is related to the car parking shed. In this case, the gate of the car parking shed automatically opens and closes when a vehicle approaches and leaves the parking shed. Final idea is to ring a calling bell in the living room when any person is detected within the range of the main door while entering the house. The four ideas verified using simulated a victual simulation tool (Tinkercad) with Arduino Uno as a microcontroller. [ABSTRACT FROM AUTHOR]
