Computer History Museum - A visit

As a child, I used to imagine that when I grow up I will work in a bookstore. I will sell books and in spare time read all the books. Whenever I get a chance to visit a big bookstore or Library, I feel as If I have entered heaven, my spine is thrilled with electric spikes.
This August, I got a chance to visit San Jose (Was there to attend an international conference ASONAM 2016 in San Francisco). Feeling a bit adventurous I tried Airbnb for the first time and stayed with Venna, a very sweet lady. When we reached, she suggested that since I am into computers I should visit Computer History Museum, I accepted her suggestion and am very happy that I did. The museum kindled the child in me, and once again I was back to childhood (not that I have really grown old), seeing the Babbage difference engine, the PDP-1, the Jacquard loom, I was transcended into a new world. The museum showcased the history of computers bringing them back to life through their gigantic exhibits. The exhibition Rev…

Development of Garden-bot: An automatic irrigation system sensing soil moisture content using self made sensor for efficient use of resources and optimum flow of water in the fields

Under the Delhi University, Innovation Project Scheme, Dr. Amita Kapoor, Dr. Suruchi Chawla, and Dr. Shallu Sharma along with the students from Electronics, Computer Science, and Instrumentation developed Garden Bot.


Garden Bot is an automated irrigation system developed to take care of your plants in your absence. In this project an app based garden bot is developed, it uses self-made low-cost capacitive sensors for the detection of water level in plants. The sensors are interfaced with Raspberry Pi microcontroller board. An algorithm was developed to detect the threshold moisture levels and control the water inflow for efficient use of water. Further, a Java-based app interface is also developed to allow manual control and inspection of the moisture content. The system is programmed using Python and Java. Garden bot can replace human labor, save the water and at the same time ensure that plants get the optimum level of water, thus increasing the life of plants.
