PQduino sends all communication by air in a simple, editable and transparent way in order you can use it and process it in the way you want.

PQduino is an electrical analyzer (only single-phase for now) based on ADE7753 chip and ESP8266 module that can monitor by default:

• Voltage (True RMS).
• Current (True RMS).
• Active power in Watt’s.
• Reactive power in var’s.
• Apparent power in va’s.
• Frequency
• Ambient Temperature
• Total Harmonic Distortion in voltage (THD V)
• Total Harmonic Distortion in current (THD I)
• Main harmonic spectrum (3° to 13° order) in voltage
• Main harmonic spectrum (3° to 13° order) in current
• Active energy accumulation
• Voltage waveform
• Current waveform

And more…

PQduino is under creation with these default parameters but can be easily extended to much more if you need, included:

• Sags & swells
• Reactive energy
• Apparent energy
• Phasor representation
• Total Demand Distortion (TDD)
• Short term flicker (PST)
• Long term flicker (PLT)

Three-phase systems are possible to monitor by using three PQduinos and integrating all single-phase data in just one central Arduino board.

PQduino incorporates OTA programing, so you don´t have to disconnect it from AC system if you want to upgrade the code.

All the code is open source, Arduino based, so you are free to play and adjust it exactly how you need.

PQduino does not need any more to operates, it already haves current and voltage sensors for direct power measuring, even PQduino haves its own power source.

Make your Arduino projects compatible with AC power systems and take your creations to another level.

Measuring Ranges

AC Voltage from 100 V to 240 V, single-phase, Line-Neutral or Line-Line. 50Hz or 60 Hz autodetected.

AC Current 5 Amp rated, 10 Amp max. If you want to measure more than 10A, PQduino Master includes a Current Transformer with 100 A range, so you can measure your entire home power consumption.
