Abstract
The whole world has been revolutionized by the mechanism of the internet of things, which not enables monitoring but also controls essential statistical data in our surroundings with the support of various devices. Monitoring environmental information such as moisture and temperature are significant for best reply of biotic structures, to each of these parameters has its effect on the evolution and processing of better crops. Real-time supervising of apparatus operating status and ecological condition as well as managing can be achieved by the facility of IoT. The data acquired from various sensors can be stored as a text file using SD card module. With the help of log file, we can also envisage when the ecosystem situation and apparatus in work status reaches an improper level, and the functioning of the apparatus must be closed or prevent for preservation. Hence, the Arduino based data logger guarantees the dependable function of apparatus, individual protection, and appropriate ecological ailment. It can also develop apparatus life expectancy and decrease the equipment breakdown rate. The data can also be made available in the cloud, using wireless sensor networks. As per the requirement, data can be stored either online or offline. This data stored will be helpful for further environmental predictions and to make decisions. Among many other variables, temperature and humidity are vital because environmental monitoring of these variables has great importance and applications in many aspects like, agricultural areas, food production, laboratories, hospitals
