| Mar 3, 2020 at 20:16 | comment | added | Filip | @Gerben Yeah that was the plan, although I measured the circuit without it and constantly reading from it and it was below 1mA, so I assumed that 1mA was the average draw just to be sure, before rewriting that part of the code, taking measurements every minute instead of taking every 2 seconds without powering off. | |
| Mar 3, 2020 at 20:04 | comment | added | Gerben | No. The Arduino needs to be "on". The Arduino polls the DHT11, say once per minute. You could remove the power from the DHT11 when it isn't used. Then re-apply power when you need a new temperature measurement. (Though you might need to add some delay between powering up, and getting a reading). | |
| Mar 3, 2020 at 10:54 | comment | added | Filip | @Gerben the DHT11 needs to be one because it will be the one providing information when asked to and alert when the temperature rises. So it always needs to be on | |
| Mar 3, 2020 at 10:50 | comment | added | Gerben | Have a look at thecavepearlproject.org . It goes into great detail on how to run the Arduino and sensors at very low currents. | |
| Mar 3, 2020 at 10:45 | comment | added | Gerben | Why do you want the DHT11 to be always on? | |
