Environmental monitoring is becoming important in today's world due to rapid industrialisation. In this paper, a web based system for monitoring various environmental parameters such as light intensity, carbon monoxide (CO) emission, temperature, humidity, and landslide is implemented. The system is implemented using Arduino Uno and raspberrypi used as a webserver. Various sensors including light dependent resistor (LDR), MQ7, DHT11, and Accelerometer sensor are used. The measured environmental parameters are uploaded on a webpage along date and time stamp. These can be viewed from anywhere using an internet enabled device such as laptop or smartphone. The software code is written using Arduino Integrated Development Environment (IDE) and Python. The webpage is developed using HTML and PHP languages. The variation of the environmental parameters is observed on ThingSpeak.

In many schools and colleges, teachers record the students' attendance in an attendance register manually. Later this data is entered in to a computer and the aggregate percentage of students' attendance is calculated. This method results in duplication of work and increases manpower requirements. In this paper, an attendance recording and consolidation system (ARCS) is implemented using Arduino and raspberrypi microcontroller boards. Arduino is used to implement the attendance recording device (ARD), whereas raspberrypi is used as a webserver. ZigBee technology is used for transmitting the attendance from the ARD to the server. A web page is created by using PHP language to display the aggregate percentage of attendance of each student corresponding to various classes in the institution. The advantages of this method are user friendly, secure and affordable.

In today's era regardless of the field of study or preference for defining data (quantitative, qualitative), accurate data collection is essential for maintaining the integrity of research. Selection of appropriate method and the device used for data acquisition reduces chances of errors occurring. Proposed system has a small handy hardware, a remote server and software components for acquisition of data manually or from sensors electronically. It could be used in doing survey's, closed loop control monitoring systems in industries, hospitals, attendance management system of schools and colleges etc. This paper presents a design and framework for taking attendance in schools and colleges, for making troublesome process of taking and compiling of attendance simple and efficient. As its targeted users are educational institutes where there is a requirement of affordable, user friendly, portable, energy efficient and secure automated system. Hence this prototype provides an amalgamated solution for replacing existing conventional attendance system with embedded attendance system. Main advantages are its very low cost, small size, efficient with low energy consumption.
