Abstract

Hydroponics is a soilless cultivation method that relies on water and the fulfillment of plant nutritional needs. Nutrient provision is usually done manually, which can be time-consuming. To improve efficiency, an automated system using sensors and an IoT-based application can be implemented. This system utilizes a TDS sensor, pH sensor, and NodeMCU ESP32 to monitor nutrient and pH levels in water. The values are displayed on an LCD screen and sent to the application. If the nutrient content falls below 700 ppm or the pH falls below 5 or above 8, indicating a nutrient deficiency, the nutrient pump can be remotely activated through the application. The pump stops when the nutrient level reaches 1000 ppm or the pH reaches 8. The system provides TDS and pH readings, which have an average error of 3.16% and 2.87%, respectively. This automated system can be used to reading TDS and pH values to assist in providing nutrients to hydroponic plants.

Abstract

A system using Internet of Things (IoT) technology has been developed to assist farmers in efficiently feeding their pet ducks. This system based on the Internet Of Things (IoT) method, involves various components such as loadcell and ultrasonic sensors, servo motors, a real-time clock, LCD display, power supply, and the NodeMCU ESP8266 microcontroller. The feeding process starts by filling the feed into a container hopper. The ultrasonic sensor detects the feed level and sends this information to the Blynk application. The application then opens servo motor 1 to drop the feed into a small container with a loadcell. The loadcell sensor measures the weight of the feed, and then servo motor 1 closes and servo motor 2 opens until the feed runs out, at which point servo motor 2 closes. The system continuously repeats this process and sends notifications to the Blynk application when the hopper is empty. Overall, this system helps to streamline the feeding process for pet ducks and improve efficiency for farmers.
