Abstract. Uncontrolled use of air conditioners leads to energy wastage and high electricity costs. Many users have not realized the power consumption pattern due to the lack of monitoring system. This research develops an AC power monitoring system using NodeMCU ESP32 and PZEM-004T sensor. Data is sent and displayed to a spreadsheet and I2C LCD in real-time, for alerts using a buzzer and Telegram notification when consumption exceeds the limit. This system helps users save energy, reduce operational costs, and increase awareness of electricity consumption.
