Measure Power Consumption Arduino

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.

Measure power consumption arduino. Let s put arduino put to sleep. Simple arduino home energy meter. A simple arduino wattmeter is designed in this project with the aim of measuring power consumed by small loads up to 12w. Step 3 next using the adapter we connect the red probe from your multimeter to the plus terminal of your power supply.

I thought it l. You integrate it directly on the raspberry board by cutting the circuit. Calculating the arduino power consumption. 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.

Let s take the same arduino uno and run the sleep code. The first difficulty is to insert the shunt between the battery s positive power point and the raspberry s vin. 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.

Now that we have a good understanding of the hardware let us open the arduino and start programming. Using the formula power voltage x current. 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.

The level of accuracy is enough. Usually i measure the consumption using an arduino and its analogical pin. Finally connect the gnd on your arduino uno to your power supply minus terminal. We chose a less intrusive possibility by integrating it in the power cable.

The main objective of this project is power measurement to reduce peak on generation by providing customers with their instantaneous power consumption. It is pretty amazing to measure a raspberry with an arduino. The code i have wake up every few seconds upon watchdog timer timeout and toggle the onboard l led. Comparing this values to the battery voltage i should get an idea of how much power consumption i have.

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.
