This study presents a wireless single-phase(1ϕ)alternating current(AC)power-monitoring module with a digital meter and based on advanced metering infrastructure architecture. The module was run on an Arduino platform with an ADS1114 analog-to-digital converter chip that integrated voltage and current sensors. The developed AC voltage and current sensing module had an inter-integrated circuit(I2C)interface standard and was further combined with a TTGO ESP32 WiFi module for wireless capabilities. The developed wireless AC power-monitoring module can surveil power grids to gather data on voltage, current, power, electricity, power factor(pf), and frequency. The proposed module can enable electrical equipment managers to conveniently monitor electric power, faults, and efficiency. The module was used to monitor a distribution box in a computer classroom at Da-Yeh university, and data on AC parameters were uploaded to ThingSpeak, a cloud-based Internet of Things platform, over WiFi. This wireless AC power-monitoring module with a standard I2C interface is a novel device that could be used in numerous power-monitoring applications. |
