Food self-sufficiency is a government program that has been actively promoted so that our country, Nigeria, can achieve food independence. Nigeria is an agricultural country with rainy and dry seasons. In the rainy season, food plants usually do not need to be watered, while in the dry season, the plants must be watered regularly according to the soil moisture conditions. Farmers usually do not grow food plants in the dry season for fear that they will not grow well due to the absence of rainfall. The farmer’s dependence on the season of rain causes the production to decline and becomes a hindrance to the success of the food self-sufficiency program in Nigeria. An information and communication technology-based agricultural device is needed to overcome this problem. This research aimed to review papers based on the design of a programmed microcontroller chip to control watering automatically based on soil moisture detected using a domestic soil moisture sensor. This device was used to detect whether the soil was dry or not. The farmers did not need to do irrigation manually all the time. In addition to helping farmers, the device could also be installed on plantations, seedbed nurseries, urban parks, hotels, offices, and homes. |
