Although intercropping gives additional yield per unit area than sole cropping, yield may also decrease as the crops differ in their competitive abilities. To avoid competition and to accompany complimentary action between the base crop and inter crop in intercropping practise, proper crop ratio of two crops should be maintained. When sowing with available seeders crop ratio was not maintained because of non-availability of a seed hopper, handling two different varieties of seeds and the un controlled seed flow from the hopper to the seed tube when ground wheel is rotating. To look after this problem an experiment was conducted at DFMPE, AEC & RI, Tamil Nadu Agricultural University, Kumulur by fabricating a seed hopper consisting of two compartments and circular shaped outlet for two variety of seeds and developing an RF (radio frequency) wireless technology to control servo motor in order to restrict the seed drop from seed hopper to the seed tube even though ground wheel is in running condition. In this paper considering a seven-row seeder, the performance of a micro controller coded with appropriate programme in embedded C language which can regulate seven servo motors each at seven seed hoppers, functioning of RF transmitter sketch, functioning of RF receiver sketch, header issue & its solution, angle conversion of servo shaft and power consumption was observed and discussed. Total power required for operating RF electronic setup containing seven servomotors was recorded as 5 V 12 A. The angle of rotation of servo motor shaft was from 0º to 165º when pulse width range in micro controller was set from 0 and 2400 micro seconds. The servo did not respond in the hardware interfacing because both the libraries use timer 1 interrupt which created an error issue. In order to overcome that “Servo timer 2.h” header was issued instead of servo.h. Then sketch was compiled and was executed successfully.

Traffic Control System

Nowadays, automatic traffic light control is becoming an important requirement for travelers and number of road users especially for emergency service providers such as ambulance drivers, fire fighters etc... Various alternatives have been proposed, but it has certain limitations.One such example is using an RF transmitter mounted on the ambulance which will communicate with the RF receiver mounted on the signal post in the traffic control system. A special algorithm is provided to control the traffic signals automatically by pressing the key provided in the keybord on the ambulance by the driver.But in this case, there is big trouble for car accidents or road accidents, because of automatic adjustment and a large number of vehicles, and there is a problem of delay in first aid service, with these overcrowded roads. This paper describes a solution that is "Intelligent Ambulance with Automatic Traffic Control” which includes the accident detecting, alerting and tracking mechanism with an automatic traffic light controlling system to overcome this delay of first aid service. An ambulance can thereby easily finde a freeway to reach the victim in a minimal time and thereby providing first aid as soon as possible. This is possible by using an RF transmitter on the ambulance which will communicate with the RF receiver mounted on the signal post in the traffic control system. To control the traffic signals automatically, and to move towards the location in minimal time, a specific algorithm is proposed in this paper. Thus, the traffic light gets controlled by the intelligent ambulance itself, in such a way that it could provide free path to the ambulance[1].

Plant population is an important attribute in crop management practice. Increasing the plant density by decreasing the crop row spacing was an alternative strategy to optimize crop profit. Hence, the field trial was conducted at Tamil Nadu Agricultural University, Coimbatore, during the winter season of 2017 – 18 to study the effect of row spacing on the growth and yield of cotton genotype TCH 1819. The experimental design was Randomized Block Design (RBD) with seven spacing treatments viz., T1: 60 x 15 cm (1,11,111 plants ha-1), T2: 60 x 20 cm (83,333 plants ha-1), T3: 75 x 15 cm (88,888 plants ha-1), T4: 75 x 20 cm (66,666 plants ha-1), T5: 75 x 30 cm (44,444 plants ha-1), T6: 90 x 15 cm (74074 plants ha-1), T7: 90 x 20cm (55,555 plants ha-1) and was replicated thrice.  Plant densities showed a significant (p=0.05) difference for all the characters studied.  The higher plant density of 1,11,111 plants (60 x 15 cm) observed significantly (p=0.05) maximum plant height (103.14 cm), Leaf Area Index (LAI) (4.35), Dry Matter Production (DMP) (8125 kg/ha), Crop Growth Rate (CGR) (6.58 g/m2/day), root length (41.46 cm), root dry weight (14.94 g/plant), and chlorophyll index (48.24).  The number of sympodial branches per plant (17) and bolls per plant (22 bolls) was found significant in the wider spacing of 75 x 30 cm.  The narrow spacing of 60 x 15 cm noted the highest seed cotton yield (2565 kg/ha), net return (R65706.62), and B: C (2.32) ratio, followed by the spacing of 75 x 15 cm due to more plant density per unit area (m2).  So, maximum yield in cotton can be achieved by decreasing the row spacing and increasing the plant population per unit area.

Extract Information

Internet of Things (IoT) plays a pivotal role in easing the work of people. Internet of Things is a system of interrelated computing devices, mechanical and digital machines, objects, animals, or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. The unique identifiers mentioned above are RF transmitters, which use electromagnetic fields to automatically identify and track tags attached to objects. Using RF technology, we will decrease manually achieved workloads considerably and RF technology is universal, useful, and efficient. The microcontroller is used to extract information from the RF transmitter and send it to the system with the help of a Wi-Fi module. By incorporating these technologies, it helps us in tracking the bicycles and do the required analysis. This project is primarily designed to monitor bicycles in a bicycle club. It is used to identify the location of bicycles that are used within a particular area. The hardware architecture consists of a transmitter, RF receiver, microcontroller, Wi-Fi module, Web server, and database server. The web server and database server are located in the master station. The RF transmitters are distributed around an open area. They are programmed with a unique ID for each bicycle. The communication between the tag reader and the webserver is done via microcontroller and Wi-Fi modules.

Paper Method

The major issue faced in restaurants and hotels is the quality of service provided by them especially ordering of food. Traditionally, it used to take a long time for food ordering as waiter used to note down orders, place it kitchen and the food was prepared. It also involved traditional pen and paper method and the process was time consuming. It also involved a lot of wastage of paper. Hence, we have designed the smart restaurant in which the orders will be placed paperless using Arduino UNO, TFT touch display connected to the kitchen chef directly using RF Transmitter. This acted as the transmitting side. At the receiving side, the order placed is seen on LCD screen and indication of buzzer with the help of RF Receiver and I2C Module confirmed the placing of order to kitchen. Hence, the workers focused on billing and other work process and provided better quality services. We found out that this method is useful in many ways like- It not only saved the wastage of paper but also reduced the burden on the waiters and workers to great extent. Time management was also done as more and more customers could be handled by taking their orders and provide quality service. This setup is quite practical on basis such that this system can be implemented for small startups hotels and restaurants. The investment cost is also one-time investment as it requires less maintenance. The only fact it requires is to update the system as per our convenience and new offers. It also required average skilled labor to operate. Hence, we can conclude that this system is eco-friendly as it saves the paper usage by directly giving the order to kitchen and chef. The second grasping factor is that the waiters can involve them in other process of billing and other process. Hence it promotes the multi-tasking process. Third factor covered is that fresh food can be served at a faster rate to the customers due to this table-kitchen friendly process. It even eliminates the errors occurred due to traditional methods and also involves constant upgradation and upliftment of the system helps in better customer end services.
