Measure Power Consumption Arduino

Comparing this values to the battery voltage i should get an idea of how much power consumption i have.

Measure power consumption arduino.

Arduino uno at 16mhz 5v 3. The code i have wake up every few seconds upon watchdog timer timeout and toggle the onboard l led. Simple arduino home energy meter. Let s take the same arduino uno and run the sleep code.

Now that we have a good understanding of the hardware let us open the arduino and start programming. Step 3 next using the adapter we connect the red probe from your multimeter to the plus terminal of your power supply. Arduino power supply is not always the first thing on your mind when you re planning a new project but it s definitely something you ll want to consider in the early stages of your project. The purpose of the code is to read the analog voltage on pin a3 and a4 and calculate the voltage current and power value and finally display it on the lcd screen.

It is pretty amazing to measure a raspberry with an arduino. Calculating the arduino power consumption. Connect the black probe to the vin on your arduino uno. A simple arduino wattmeter is designed in this project with the aim of measuring power consumed by small loads up to 12w.

The first difficulty is to insert the shunt between the battery s positive power point and the raspberry s vin. In a future implementation as an extension to this project i will design a new circuit based on voltage and current sensors for more accurate results. We chose a less intrusive possibility by integrating it in the power cable. Let s put arduino put to sleep.

Usually i measure the consumption using an arduino and its analogical pin. The level of accuracy is enough. There is need for accurate and economic methods of voltage and current measurement using arduino. In this post we ll get to know the different power supply options for your project and how you can optimize your power consumption.

I was walking through the hardware store the other day and i walked past an energy meter which clips onto your home s electricity mains and then provides you with information on your power consumption and cost estimates for the month. Using the formula power voltage x current. Finally connect the gnd on your arduino uno to your power supply minus terminal. Power 5v 46 5ma 232 5mw.

In this case my idea is to attach to every component a relatively small resistor and see which is the voltage of this resistors.
