GSM based Stock Empty or Full indicator using Weight sensor

Description:

GSM based Stock Empty or Full indicator using Weight sensor is used to get a SMS indication whenever stock or storage is Full (or empty). There are two threshold levels, Full and Empty. Threshold value is decided using a Toggle switch. So when toggle switch is at Full condition then SMS will be sent when stock is Full. And when toggle switch is at empty condition then SMS is generated when storage is empty. This project can be used at companies, offices and even in our home or schools for monitoring various stocks and storage.
