I am working on an project that requires power for these parts: sensor SHT15, RN-XV Wifly Module, CO2 Meter sensor, TSL2561 sensor,Breakout board for electred microphone, RTC (DS1307), sd card, and Wireless SD Shield.
I would like very much you to give me tips on how to calculate consumption the my project.
I'd allow around 60mA for the board with nothing connected to it.
Excuse my ignorance but I'm doing a final course work and had little electronics so I'm a bit lost! How do I measure? Using an ammeter? So I can not measure the total consumption with sensors and everything?
Yes, just put your ammeter in series.
On some meters you need to put the probes in a different socket.
Start with the highest current range, and work downwards
So I can not measure the total consumption with sensors and everything?
You can but this is not what you asked, you said:-
how to calculate consumption the my project.
Maybe I have not explained well ... My objective is to size a battery and for that I need to know the total consumption (sensor + arduino) right? I've tried a battery with 7Ah but discharged last half hour ...
Connected to the arduino uno have a temperature sensor and relative humidity (SHT15), RN-XV WiFly Module, a sensor CO2 Meter, illuminance sensor (TSL2561), a electred microphone, RTC (DS1307), sd card and Wireless SD Shield. My project is to make reading of data recorded by the sensors, record them on sd card and sends them to your computer via wifi.
The battery can not be good because it is very strange that it happened ... When I calculated the consumption of sensors (considered the maximum current they consume) gave me around 80 mA, not considering the sd card (which I think is around 100 mA) or consumption of arduino!
I also not know what that means ...
This battery was what was available to bind to arduino to see how long it could handle! As discharged so quickly and with no other available I was asked to calculate the total consumption in order to get a sense of the battery I can use ... But being complicated ...
