Digital Portable Weather Station Monitoring System Using Arduino Uno

The temperature,humidity,atmospheric pressure and altitude are the most important parameters of the environment.If those parameters are known,it will help to select the best crops for specific location which increases the productivity in agricultural field.This is very useful for countries like Nepal where the most of people in this country depends on agriculture.In this research,an Arduino based device is constructed which measures those parameters and record the data in real time.The DHT22 and BMP180 sen­sors are used for measuring those parameters whereas RTC and SD Card module is used to record the data in real time.Data can be displayed on LCD and serial monitor of computer or laptop.The data were collected at Tri-Chandra Multiple College,Ghantaghar and at Gaurighat,Chabahil with the help of Arduino based device.In this project,the digital portable weather station monitoring system has been designed and data from this device compared with the data obtained from HTC-2 standard device and error analysis has been done.

Design of Digital Solar Water Pump Using Microcontroller ATmega 32

This paper focuses on the application of solar energy along with microcontrollers to design and run a motor to pump water from various sources.The solar water pump is one of the applications or appliance that perform task with the use of solar radiation.The solar water pump consists of solar PV array,solar pump,inverter,AC water pumping device etc.Solar energy radiation is converted in electrical current or power source which is then used to run a pump and draw water directly from ground,wells,rivers,lakes etc.In this paper,the relationship between flow rate of the water and luminous intensity of the solar irradiance is studied and the data are linearly fitted to find out the correlation between these parameters.Also the study about efficiency of the solar powered water pump shows that the operation of this type of pumping system is quite efficient than other types of fossil fuel engines like diesel,petrol,kerosene etc.in long run.The use of Arduino Uno,flow sensor,LDR sensors in the solar powered water pump helps to analyze the relation between these parameters and know the conditions favorable for excess supply of water in short time efficiently.These solar powered devices are the future of clean and green future of this world.Thus it is not only necessary but also compulsory to enhance the usage of solar energy throughout the globe.

Designing of the Wireless Digital Portable Temperature and Humidity Monitoring Device and Analyzing Data at Different Part of Kathmandu Valley

The atmosphere of planet plays a great role in numerous weather phe­nomena which affects our life directly.To understand these phenomena,it requires knowledge about the relation between temperature and humidity.The effects of temperature on humidity influence the potential for precipi­tation.It also directly influences the human health and well-being.Relative humidity and dew point are the two parameters that are used by the meteo­rologists for understanding the interaction between temperature and humid­ity.Therefore there is a necessary of a smart monitoring system which is fully automated,accurate and capable enough to monitor all the parameters with accuracy.Besides,it should be portable and less expensive.For this purpose,the digital portable wireless temperature and humidity monitoring device is designed.This project consists of HC-05 Bluetooth module,DHT-11,Arduino UNO,16 X 2 LCD,and smartphone.The data are recorded at different part of Kathmandu Valley with this device wirelessly by using smartphone and analyze it with the help of Origin software.
