Backlight for LCD display unit

Embedded systems in Agriculture play a vital role in unifying the work involved and improve conservations. Designing a smart as well as a cost efficient and more user-friendly system will be idealistic challenge. The following system that has been proposed is designed with those ideal constraints in mind. It consists of a Raspberry pi3 as a gateway that links the sensor networks with the cloud. To improve security an MQTT protocol is used for cloud connectivity. The communication between the sensor networks is managed by NRF24L01. The Sensor network is a separate entity that can used like a plug and play device and is built by a micro controller with a LCD display and an interfaced GPS. Multicasting is also possible between sensor networks and the gateway. The processed data from the sensor networks is sent through NRF24L01 to the gateway. The gateway further processes and encapsulates the data and through MQTT the data gets stored on the cloud. This cloud data can be accessed through computer or mobile device

Visual Display Unit

The basic requirements of any automated system for collecting and processing data for a diary herd are that:-- it must present the information required for day-to-day management in an easy and readily available form.- it will be justified only if the system provides useful management data that would be more costly to produce in other ways or be impractical to obtain manually- it should be built from a simple base with add-on units to a complete system, to allow for various sizes of herd, levels of technical development and cost. (Inputs could be either from manual records or automatic recorders)- it should provide information on a visual display unit, with lists printed when required- accurate identification is essential especially if automatic identification is used- it should be developed to a fully computerized farm recording system.
