According to Kunla Singh (2015), Automatic Fan Speed Control system utilizing Arduino as we all know that we are slowly moving toward automation and Automation is among the trending topics. Basically in this project will be controlling the fan speed with respect to the temperature. The system will get the temperature from the temperature sensor and it’ll control the speed according to the temperature, set by the person.

In this project, microcontroller varieties the processing parts, which firstly senses the temperature and the controller then compares the information with the set temperature. If the current temperature is larger than the set temperature, the controller turns ON the fan and the set pace shall be proportional to the difference between the set temperature and the current temperature. If the present temperature is less than the set temperature, the fan shall be turned OFF.

The fan’s velocity will change according to the temperature.

Moreover, RipunjayChachan (2015), said designing an clever Temperature-Cum-Humidity monitoring gadget is depicted in this present project. The designing of the absolutely practical prototype is developed in-house. Once the humidity of the temperature will get out of the range talked about by the consumer the device sends an SMS to the user’s predefined number. This SMS contains data on the present temperature and the humidity. The developed system is also in a place to ship the data to the monitoring station for recording and graph plotting for analyzing functions on the later stage.

The developed system has been tested beneath numerous simulated conditions.

Jeffrey Alan Siegfried (2016) Remote Sensing to Quantify in-field soil moisture variability in irrigated maize manufacturing, Agriculture is the biggest shopper of water globally. As strain on out there water resources will increase, the want to exploit know-how so as to produce more meals with much less water becomes crucial. The technological hardware requisite for precise water supply methods corresponding to variable rate irrigation is commercially available. Despite that, strategies to formulate a well timed, accurate prescription for these systems are inadequate. Spectral vegetation indices, particularly Normalized Difference Vegetation Index, are sometimes used to gauge crop vigor and related parameters (e.g. leaf nitrogen content and grain yield). However, research rarely addresses the affect of soil moisture on the indices. Canopy temperature measured using cheap infrared thermometers could additionally serve as an indicator of water stress, however present methods which exploit the data may be cumbersome

Edwin Basnet (2016) Smart Greenhouse Automation system Applying moving common algorithm, Automation of greenhouses has proved to be extraordinarily helpful in maximizing crop yields and minimizing labor costs. The optimum situations for cultivating crops are often maintained by means of programmed sensors and actuators with fixed monitoring of the system. In this paper, we’ve designed a prototype of a smart greenhouse utilizing Arduino microcontroller, simple but improved in feedbacks and algorithms. Only three necessary microclimatic parameters namely moisture stage, temperature, and lightweight are considered for the design of the system. Signals acquired from the sensors are first isolated and filtered to scale back noise before it’s processed by Arduino. With the assistance of the LabVIEW program, Time domain evaluation and Fast Fourier Transform (FFT) of the acquired alerts are carried out to research the waveform. Especially, for smoothing the outlying data digitally, Moving average algorithm is designed. With the implementation of this algorithm, variations within the sensed information which might happen from quickly altering surroundings or imprecise sensors could possibly be largely smoothed and steady output could be created. Also, actuators are controlled with fixed feedbacks to ensure desired conditions are all the time met.
