Arduino Nano: Toda a informação sobre o consumo de energia

by Johannes

Se quiser executar o seu Arduino Nano 24 horas por dia, deve estar atento ao consumo de energia. Com o tempo, mesmo muitos pequenos consumidores podem levar a elevados custos de electricidade

Consumo de energia e custos de energia do Arduino Nano

Comparado com outros microcontroladores, o Arduino Nano tem um consumo de energia bastante baixo. No entanto, o consumo de energia nem sempre é o mesmo.

  • Em funcionamento normal, o Arduino Nano consome cerca de 25 mA. Quando o Arduino muda para o modo standby, consome apenas cerca de 7,5 mA.
  • Se ligar mais componentes ao Arduino, o consumo de energia irá naturalmente aumentar. Pode usar um multímetro para ler o consumo real de energia
  • Se o Arduino funciona dia e noite com uma tensão de 5 volts, uma corrente de 25 mA resulta em cerca de 30 cêntimos em custos de electricidade por ano.
  • É possível reduzir ainda mais o consumo de energia utilizando uma biblioteca externa de baixa energia. Isto reduz o consumo de energia principalmente em modo de inactividade.
