SISTEM MONITORING PENGGUNAAN BEBAN LISTRIK BERBASIS IoT

In recent years the development of technology is increasingly advanced, and of course more sophisticated, especially in the field of electronics. With the advancement and development of technology in the field of electronics we are increasingly facilitated in any case, for example the use of electronic equipment at home. With advances in technology in the electronics field, we can create an IoT-based remote control and monitoring system for electrical loads by utilizing the internet as a communication tool with the system. This system will control and monitor through the Telegram application, later the application will display the use of voltage, current, power, temperature, and humidity. Nodemcu which will support the process by sending data obtained from the PZEM-004T sensor and DHT11 sensor, the data will be sent to the user via the telegram application, the user can also control the condition of the lights connected to the system. From several times of testing to compare the output value of the sensor with a measuring instrument Tang Ampere and also a Hygrometer. The error value obtained from this system is quite low, namely the DHT11 sensor has an error value of 0.26, the PZEM-004T sensor gets an error value of 0.58 for voltage, an error value of 0.086 for current, and an error value of 7.65 for power
