The e-Crop device helps farmers grow crops better by calculating how much food a plant can produce based on sunlight, water, and other factors. It tells farmers what their crops need to grow well and gives them advice on when to water, add nutrients, and protect plants from pests. The device can predict how much food a crop will make more accurately, and it sends farmers text messages with helpful information. Farmers can use one device for different crops in the same area with similar weather. This device is a useful tool for farmers because it gives them real-time data on soil and weather conditions, helping them make better decisions for their crops.
