Measure Power Consumption Arduino

Measure power consumption arduino.

Simple arduino home energy meter. Usually i measure the consumption using an arduino and its analogical pin. In this post we ll get to know the different power supply options for your project and how you can optimize your power consumption. Now that we have a good understanding of the hardware let us open the arduino and start programming.

The code i have wake up every few seconds upon watchdog timer timeout and toggle the onboard l led. Calculating the arduino power consumption. The level of accuracy is enough. 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.

Comparing this values to the battery voltage i should get an idea of how much power consumption i have. There is need for accurate and economic methods of voltage and current measurement using arduino. It is pretty amazing to measure a raspberry with an arduino. Arduino uno at 16mhz 5v 3.

The main objective of this project is power measurement to reduce peak on generation by providing customers with their instantaneous power consumption. Connect the black probe to the vin on your arduino uno. We chose a less intrusive possibility by integrating it in the power cable. A simple arduino wattmeter is designed in this project with the aim of measuring power consumed by small loads up to 12w.

I thought it l. Let s take the same arduino uno and run the sleep code. In this case my idea is to attach to every component a relatively small resistor and see which is the voltage of this resistors. Finally connect the gnd on your arduino uno to your power supply minus terminal.

Step 3 next using the adapter we connect the red probe from your multimeter to the plus terminal of your power supply. You integrate it directly on the raspberry board by cutting the circuit. 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 first difficulty is to insert the shunt between the battery s positive power point and the raspberry s vin.

Let s put arduino put to sleep.
