Arduino Home Energy Monitor using CT Clamp Current Sensor & ZMPT101B AC Voltage Sensor

Arduino Home Energy Monitor using CT Clamp Current Sensor & ZMPT101B AC Voltage Sensor

In today’s episode, you will learn how to make Arduino Home Energy Monitor using CT Clamp Current Sensor, ZMPT101B AC voltage Sensor, and an SSD1306 I2C-supported Oled display module. Instead of using the Arduino Nano you can also use Arduino Uno.

After calculating voltage, current, and power, you can easily calculate the units. you can calculate how much electricity you have used in a day or even in an entire month. When you have the values of voltage, current, and power, you can calculate anything by using the desired formula.

For the current transformer (CT), the AC voltage ranges from -1V to +1V. However, the Arduino's Analog-to-Digital Converter (ADC) cannot process negative values. To address this, you need to establish a virtual ground, ensuring the AC signal stays within the positive range. If you set the virtual ground at 2.5V, for a 5V system, the maximum values could range from 1.5V to 3.5V. To achieve this, employ an appropriate resistor divider. Additionally, incorporate a capacitor alongside the top resistor in the divider to function as a high-pass filter. This setup should be calculated to allow frequencies around 10Hz, which is adequate for handling the usual AC signal frequencies of 50 or 60Hz. As per the Nyquist Theorem, your ADC's sampling rate must be at least double the frequency of the signal you're measuring. In practice, I often use an external 16-bit ADC and have optimized my code to sample at a rate of 800-900 samples per second for reliable measurements.

This looks interesting. I would like something to measure and record voltage spikes on the AC line (mains). I will have to look at the specs and see if the two sensors (especially the voltage sensor) are capable of measuring and capturing a fast spike, such as the standard 8/20 μS waveform. It might even be the Arduino that would be the limiting factor.

How may I use ZMPT101B AC Voltage Sensor to monitor two phases?
I probably will need two sensors but how may implement them together?

[pramodjalgaonkar]

Sir can i measure dc current with this sensor ? THANKS FOR ANS 😊😊😊

[anshulchauhan]

can you tell a good current sensor for measuring dc current other than ACS712 sensor as it is not providing proper reading

[chuhaohuang]

Hey bro, can u tell me how to buy the translator of 3.5mm earphone port to the GPIO? thx

[MuhammadKamran-nh]

can we use any other sensor instead of sct 103

[d]

i wish to know how to integrate the ct clamp to a development board....i want t everything on a pcb

[BhatakantiEkPravas]

One of the worst CT, used all codes, circuit and calibration method still not worked😢

[pramodjalgaonkar]

Sir can i measure dc current on digital meter. Home light meter.

[irfanarefin]

how to measure power factor on this method?

[AbdulRahman-enow]

1:36 it is better to replace it with invertor, the k-electric bill would be out of the world
