The use of IoT is increasing day by day; the significance and utilization is on the increase with more sophistication. In real world situation the electricity board calculates the bill amount and passed to the user mail or EB card. Now an efficient power monitoring system is proposed which uses a sensor at the heap to ascertain current, a circuit is utilized to figure voltage and with these two, power can be computed. Control qualities are put away in cloud database. Noninvasive current transformer sensor which receives the input from the live power supply and transfer the value to Voltage sensor, Nodemcu gets the value from voltage sensor and stores it in cloud database. With the help of cloud database user can monitor the power consumption value. Home automation can be achieved with the help of Relay Module and separate Nodemcu. Devices can be controlled from cloud dashboard. EB bill is a big challenging expenditure on day to day life. To overcome this situation Power Monitoring System will be very useful for the Average Salary people and also it overcomes the Electricity theft, unwanted Power wastage, avoidance of high power consumption devices.

物联网的使用日益增加；随着越来越复杂，重要性和利用率正在增加。在现实世界的情况下，电力板计算账单金额并传递给用户邮件或 EB 卡。现在提出了一种高效的电力监控系统，它使用堆上的传感器来确定电流，利用电路来计算电压，并通过这两者来计算电力。控制质量存放在云数据库中。无创电流互感器传感器接收来自带电电源的输入并将值传输到电压传感器，Nodemcu从电压传感器获取值并将其存储在云数据库中。借助云数据库，用户可以监控功耗值。借助 Relay Module 和单独的 Nodemcu 可以实现家庭自动化。可以从云仪表板控制设备。EB 账单是日常生活中一项极具挑战性的支出。为了克服这种情况，电力监控系统将对平均工资的人非常有用，它还克服了电力盗窃、不必要的电力浪费、避免使用高功耗设备。
