India is a country that focuses on raising crops. The agricultural understanding was everything to our ancient populations. The majority of Indians depend on agriculture for their daily needs, and it has a significant impact on the nation's economy. Irrigation becomes challenging in dry areas or cases of little rainfall. To provide the best results and safeguard farmers, it must be forced upon them. A substantial role is played by horticulture, a subsector of agriculture, in the economy, human nutrition, gender mainstreaming, and employment. Fruits, vegetables, flowers, spices, and sauces are examples of horticultural goods, which have continuously increased and now make up a significant portion of the agricultural trade. The purpose of the automatic irrigation control system is to decrease the efforts of the human operator (gardener) in horticulture operations. The goal of the horticulture system is to maintain measures of food security. Farmlands have historically had their soil moisture levels checked manually. This is frequently time-consuming and ineffective, thus a method that is effective at regulating and keeping track of soil moisture levels is required. To communicate data from the board to the user's smartphone or laptop, this study presents an Internet of Things (IoT)-based soil moisture monitor that uses ESP32 with an integrated Wi-Fi module to monitor soil moisture level. The soil moisture monitors measure the amount of water in the soil and notify the farmer when the moisture sensor's predetermined threshold rate rises or falls, indicating overwatering or underwatering, respectively. This control system is based on an Arduino that has been coded in embedded C. Data from the sensor is also transmitted during this procedure, first to the cloud and subsequently to the database server. By ensuring that water is not wasted, the proposed soil moisture monitor's evaluation utilizing ThingSpeak.
