Design of Controlling and Monitoring System for Room Temperature, Lighting, Power, and Energy Using Internet of Things

One goal of a smart home is to save the use of energy. Savings can be made with a control system where the things related to electricity usage will be controlled automatically. This research designs a control system of several parameters in a replica of a room with a monitoring application. Those parameters include room temperature, lighting, voltage, current, power, and energy using the Internet of Things. The room temperature control system uses the DHT11 sensor, the light intensity controller uses the LDR HL01 sensor module, while measuring current, voltage, power, and electrical energy at the load uses the PZEM-004T sensor. The NodeMCU ESP8266 is used as a control center that receives, processes, and sends data to the Blynk application using WiFi. The core of the system is based on the detection of the room temperature threshold and the state of light intensity based on light or dark. From these two conditions, the control center will instruct the relay to turn on or turn off the fan and lighting according to the predefined conditions. If the load is on then the voltage, current, power, and energy data will be acquired and displayed on the Blynk application in real-time

Watering Strawberry (Fragaria X Anannasa) Plants in a Greenhouse Using IoT-Based Drip Irrigation

Strawberries are horticultural plants that are relatively sensitive to excess and lack of water; therefore, it is necessary to provide drip irrigation with an IoT-based control system to maintain the availability of water for plants to support good plant growth and facilitate the work of strawberry farmers. The purpose of using an IoT-based watering control system on strawberry plants (Fragaria X Annanasa) based on water needs in plants is used to support the development and progress of drip irrigation systems and smart farming system technology in modern agriculture. The research methodology is the preparation of tools and materials, assembling and testing the control system, placing sensors in three different scenarios, and observing the height and number of leaves of strawberry plants with different watering frequencies. The results of the design and testing show that the placement of the sensor on the planting media produces a reading value that is close to the actual volume of water by producing a volume of 51.6 ml of water, which is 79.51% of the weight of the growing media used. And for the growth of plants, watering every two days was better, with the average height and number of leaves for strawberry plants being 0.4 cm and 1.78 strands

IoT-based Electrical Power Recording using ESP32 and PZEM-004T Microcontrollers

The electricity usage recording system in Indonesia still uses conventional kWh meters. Electricity usage is recorded by officers who visit customers' homes every month. This results in the electricity company having to provide employees who become a burden on the company's costs. Technological advances enable convergence between communication channels and various things. A technology known as the Internet of Things (IoT) allows customer kWh meters to be recorded in real-time. This research aims to create an Internet of Things (IoT)-based kWh meter that can make it easier for electricity companies to monitor each customer's electricity usage. The IoT kWh meter created can be monitored and controlled from a remote location in real-time. If there is a change in load usage, it will be monitored directly via a mobile device because the kWh meter is directly connected to the internet network and cloud server. To determine the functionality of the tool being made, several tests were carried out, such as a) sensor testing, b) LED indicator, buzzer, and relay testing, c) OLED display testing, d) Firebase database testing, and e) load testing. The test results obtained are used to calculate the error of the tool made with a comparator, and the results show that the percentage of voltage error with different loads is very small, namely 0.35% and 1.45%. This research produced a prototype using ESP32 and PZEM-004T, which is so accurate that it is recommended for recording electrical power, which can reduce the burden on operational costs for electricity companies
