Electronic Grain Dispenser Synopsis
Need of the project
In India in difficult times of covid-19 government of india announced the free ration food distribution for 9 months. This food supply of grains of wheat and rice is distributed at Government operated Ration shops all over india. The distribution is done conventional weighing system of fixed weight in bowls and pouring in customer bags. For this a labour has to lift 50 kg bags and using smaller bowls put the grains in bigger bowl for weighing required amount of grains, after weighing is done, grain are poured into customer bags. This process is physical and requires human effort which is tiresome and labour intensive. This project helps in this
Principle of Operation
A funnel of 10 kg will be having a spindle inside to stir the grains in the funnel, as the spindle spins inside the funnel the grains will start pouring out from the funnel. The grains are collected into bowl and the bowl is placed on electronic weighing scale below funnel. The weighing scale will trigger the spindle to stop when a preset weight of grains are in bowl/customerbag. Stopping of the spindle will stop pouring of the grains and desired amount of grains are automatically distributed to the customer without labor intensive distribution of the grains
This avoids person to person contact and provides automated process to distribute
Computation Part
Spining == true if Bowlweight < 5kg
Spinning == false if Bowlweight >= 5kg
Components Used
- Funnel 10 kg
- spindle with motor connection
- motor and weigh scale connected to printed ciruit board (ardiuno /raspberry) anything that is feasible
Applications
- Rations shops
- Grocery shops
- Cement factories
- Chemical shops
- Restaurants
Electronic Vault
Need of the Project
A vault is an important aspect everyone personal life to protect and secure personal belongings. Conventional methods are to put a mechanical lock which has a key to the latch. We need to keep the key with us always and is always required to open the lock. however to automate we use few electronic components to build vault of our own and which can be opened by a 4 digit password
Principle of Operation
A latch is created and attached to motor which is mounted the inside wall of the door of the vault. A numeric keypad is mounted on the outside of door of the vault. When a correct password is inputed on the keypad the motor spins the latch inside the door and door can be opened. This is small appliction to create the vault but a valid project to showcase motor connection skills , ardiuno like pcb programming and keypad connection and operation
Computation Part
Keypad input == password => Move the motor spindle to 180 degree and open the door
Keypad input != password => Door can not be opened => latch present
Components
- Numeric keypad
- motor
- Vault box
- ardiuno like pcb
Applications
- Banks for keeping important documents
- Houses for securing personal belongings
- Restaurants can be used in refrigerators
Ardiuno Camera based Monitoring Device
