IOT based Energy Monitoring for Practical Loads using NodeMCU
Authors: , , ,
Abstract: Electrical energy monitoring is increasingly important nowadays for residential and commercial usage. The energy meters are installed in consumer’s houses to track their energy usage. There are many chances of human mistakes for every electricity consumer while recording the manual energy meter reading in their houses. Also, the consumer does not have updated information about current electricity usage in each hour, day, and month. To overcome the above problems, the system is developed to remotely monitor from any world location using the NodeMCU and Arduino IDE. The energy monitoring is carried out by using the Node MCU, Arduino IDE, and PZEM-004T sensor. The PZEM-004T module is coupled to the Arduino controller. The sensor module receives a signal from the CT coil which is connected to load. The load parameters such as voltage current power etc., are measured and transferred to the Arduino. A NodeMCU ESP8266 is utilized as a Wi-Fi chip system. By using a Wi-Fi connection and the internet, the acquired data is sent to Thing Speak to save in the cloud to monitor the measured parameters remotely. The power analyzer instrument is also used to measure the real-time parameters consumed by the load which is used to cross verification and compare with the sensor measuring parameters. The passive load resistance, inductance, and 100-watt lamp loads are experimentally connected and tested. The load consumed electrical parameters such as current, voltage, power, power factor, real power, and frequency are monitored in online. Energy monitoring online may reduce the consumer's mistakes by recording the parameters and consumers can know each hour, day, and month's energy consumption up to date according to their usage.
