IoT based Monitoring and Investigation of the Effect of Water Level, Temperature and humidity to the Hydroponic based plant

Hydroponic plant system cultivate different plants without utilizing the soil. The purpose of the paper is to monitor and analyze the parameters of hydroponic system sensors which include Water Level Sensor, pH water level sensor, and DHT11 (Humidity and Temperature sensor). This sensor will monitor the water supply level, humidity, and temperature of the plant, and also pH water level. Moreover, to make this hydroponic plant into ‘Smart Hydroponic Plant System’ is we implement a low-cost, low-power system on a chip microcontroller with integrated Wi-Fi and dual-mode Bluetooth called as ESP32 to control the pump. The pump will draw water from a tank connected. This component will able farmer to monitor their plant through their computer. In another words, the ESP32 is a bridge for the hardware or plant to communicate with device such as smartphones.
