Abstract: The present disclosure relates to a harvesting system for variety of grain crops. The harvesting system comprises a harvester control unit, a grain loss monitoring GLM-ECU, a cloud communication interface ECU, a plurality of sensors, a controller area network (CAN), a buzzer/alarming device, a display unit, a cloud and a mobile application. The GLM-ECU is configured to process signals from a sieve sensor and a straw walker sensor. The harvester control unit is configured to process signals received from the plurality of sensors and the cloud communication interface ECU serves as an interface to interchange the data between the harvester control unit and the cloud . The harvester system results in increase in productivity and trust among the stake holders by virtue of real-time information sharing.
