hvsadmin — Sat, 11 Oct 2025 11:46:46 +0000

An umbrella is much needed product in rainy season. The problems associated with umbrellas are that it needs to be carried separately along with our other stuff and it occupies one hand all the time. Also, umbrellas are to be kept separately in buckets which lead to people forgetting about umbrella in many cases and losing them.

Well, we here design a smart solution to all umbrella related problems with a customized solution. Our proposed device is a bag pack that has an integrated umbrella with auto rain sensing. The umbrella does not need to be carried separately and both hands of the user are free even when the umbrella is open. Even opening the umbrella is an automatic operation with no manual efforts needed.

This rain sensing modern umbrella provides the following advantages:

Hands free usage
Bag attached umbrella no need to carry separately
No risk of forgetting or loosing umbrella
Rain sensing feature for automatic opening
Protects from rain as well as sunlight as needed

The modern umbrella consists of servo motorized system with transparent plastic cover with rain sensor and Arduino controller integrated in a bapack. The rain sensing umbrella system is a unique modern-day gadget that changes the way umbrella is used.

The rain sensor is used to detect rain fall. If rainfall is detected, the sensor sends trigger to the arduino controller. The arduino now operates the servo motors to open the small umbrella to protect bag from rain.

HVS-3639. Green house monitoring system using Raspberry pi

hvsadmin — Thu, 18 Sep 2025 08:37:57 +0000

A green house is where plants such as flowers and vegetables are grown. Greenhouse’s warmup during the day when sun-rays penetrates through it, which heats the plant, soil and structure. Green houses help to protect crops from many diseases, particularly those that are soil borne and splash onto plants in the rain. Greenhouse effect is a natural phenomenon and beneficial to human being. Numerous farmers fail to get good profits from the greenhouse crops for the reason that they can’t manage two essential factors, which determines plant growth as well as productivity. Green house temperature should not go below a certain degree, High humidity can result to crop transpiration, condensation of water vapour on various greenhouse surfaces, and water evaporation from the humid soil. To overcome such challenges, this greenhouse monitoring and control system comes to rescue.

This project demonstrates the design and implementation of a various sensors for greenhouse environment monitoring and controlling. This greenhouse control system is powered BY RASPBERRY PI ZERO W it consists of DHT11; it can detect both Humidity& temperature sensor, soil moisture sensor; it can detect moisture content in soil, Rain sensor to detects the rain sensor, LCD display module, DC fan and water pump. Based on the moisture content in soil, Raspberry Pi will turn ON/OFF the water motor through relay. Here relay works as a switch to ON/OFF the water motor. If the system detects high humidity, it will turn ON the DC motor to control the humidity.

HVS-3315. Solar powered automatic field crop protection.

hvsadmin — Tue, 02 Sep 2025 06:28:13 +0000

The main aim of the project is to design an automotive rain operated roof using solar energy to protect the field crops from rain. This project uses temperature and soil moisture sensor to detect the temperature and moisture content in soil and based on that it will switches ON/OFF the irrigation motor.

As human beings we cannot control the natural phenomenon such as rain, humidity, high temperature, etc. Some of the measures are taken against this environmental hazard but they are performed manually. In the Current system there is no protection for crops against natural disasters such as Floods, Rains and as well as from over Sun heat. Which are in turn Reduces the plant growth in turn reduces yield. In this project we are proposing the system which prevents the spoilage of crops due to heavy rains. This is achieved with embedded system design using sensors. Here comes the need of automation. Automation greatly decreases the need for human sensory and mental requirements as well. An automation system consisting of a connection between hardware and software has freed the individuals from their day-to-day chores. In this project we try to establish new intelligent system which helps to protect the crops against environmental impact like rain.

When the Rain falls on sensor it will detect and process this signal to the Arduino then Arduino cover the roof on crops with the help of dc motors. When the soil moisture sensor detects low level moisture in soil then Arduino uno will switch ON the irrigation motor. When the soil moisture detects moisture content in soil Arduino will switch OFF the irrigation motors. Based on the temperature value also Arduino will control the DC water pump through driver circuit. To do this task controller is programmed with in Embedded C language. In this project solar energy is stored into the rechargeable battery and this battery power is used to switch ON/OFF the irrigation motor and water pump.

Technological advances play an important role in all fields including in the realm of Agricultural Engineering. Agricultural Engineering is a field of science that has a lot to do with the development of agricultural technology. Utilization of technology in agriculture can optimize the performance of farmers. Hence, technology in the realm of agriculture is increasingly being developed. One approach is by utilizing the internet network to conduct a monitoring system in a greenhouse.

Greenhouse is defined as a constructed building that functions to manipulate the desired environmental conditions in plant maintenance, so that plants will be more controlled and provide more optimal results compared to plants that are cultivated outside the greenhouse. However, the use of internet technology in greenhouse monitoring systems is still limited. Based on this, the author wants to utilize the internet by creating a greenhouse system that can be monitored remotely with an internet network using the thingspeak application on smartphone.

NODEMCU will control the Fan speed according to the temperature and it will control the water pump based on soil moisture sensor. Node MCU continuously read the sensor data and control the devices accordingly and also upload this sensor data into the thingspeak cloud along with date and time. User can access this sensor data with his credential from anywhere in the world by using mobile.

The system makes use of NodeMCU microcontroller. The project aims in designing a smart farm using IOT and NodeMCU module. NodeMCU is an open-source platform based on ESP8266 which can connect objects and let data transfer using the Wi-Fi protocol.
