Smart Seed Machine Controller
client synopsis
India based Agriculture client wants to design the Smart Seed Machine Controller, to autonomously control the Seeding machine.
business challenge
The client needs a solution in the existing system only. In the existing system, they do all the functions manually.
Design the hardware and firmware according to the existing system, which can feet appropriately to the ground wheel.
The hardware which is robust and works in any hazardous climate situation.
The client need solution which can maintain the seed to seed distance manually and adjust the seed pitch accordingly.
Additionally, we have to synchronize and maintain the seed pitch with respect to the tractor speed controller which can allow the farmer to add the seed to seed distance for the different types of seed.
Contribution by dotcom
The prime purpose of the controller is to synchronize and maintain the seed pitch with respect to the tractor speed controller, which allow the farmer to add the seed to seed distance for the different type of the seed.
We have developed the Smart Seed Machine Controller System which can maintain row to row space, maintain the distance between the seed, depth of the seeds, and cover the seed with the soil, seed to seed space & depth, and compaction over the seed.
impacts
-
The farmer doesn't have to spend money on manpower.
-
It saves a lot of energy, efforts and time of the farmer.
-
Saves the labor cost.
-
To give high yield crops.
-
One at a time multiple seeds can be the crop.
-
Reduce the wastage of the seeds.
Indoor Oxygen Maintenance System
client synopsis
The client has a blurry idea that he wants to maintain the level of the oxygen at indoor work premises for the batter work efficiencies.
business challenge
According to the research it depicts that we spent more time in indoor than the outdoor and indoor air quality is 8 times worse than the outdoor.
We have recognized the problem that if the oxygen level decreases in the closed environment then it directly affects on the human body. We human’s exhale carbon dioxide (Co2), concentrations of Co2 in occupied indoor spaces are higher than concentrations outdoors.
Due to the low level of oxygen, it may cause the problem such as low work performance, shortness of breath, headache, restlessness, dizziness, high blood pressure, chest pain, lower decision making, uneasiness, and rapid breathing, etc.
The body can store food, water but it can't store oxygen. Every minute that we are alive, we must continuously provide our cells with a stream of fresh oxygen.
And for that reason, the client wants to generate artificial oxygen when the level of oxygen is reduced by 21% in indoor premises.
Contribution by dotcom
dotcom has designed the stupendous solution for Smart Oxygen Monitoring system.
To measure the oxygen level for the indoor premises we have used the alpha O2 sensor and the calibration of the sensor is difficult but even though we have made possible.
Design the firmware in such a way that if the oxygen level decreases below the 21% then wireless sensor node sends a command signal to another controller node that will be connected to an oxygen cylinder and that will trigger the oxygen cylinder.
Each controller node contains the solenoid gas valve that will open the cylinder cock in order to spray the oxygen. As soon as the level of the oxygen reaches to satisfactory, the sensor node once again sends the control command to the controller board to turn off the oxygen cylinder.
impacts
-
Improve indoor environment quality by generating artificial oxygen.
-
People are more efficient in their work and also increase their decision making.
-
If the human body gets the exact amount of oxygen then it makes them fresh all the time.
-
The exact amount of oxygen can save us from many diseases.
-
According to research, it shows that if the human body gets the exact amount of data then they don't need to do exercise also.
