I would like to put atmega328P in deep sleep mode with lowest possible current draw (preferably less than 5uA) and wake it up every 15-30 minutes (timer0/1) to read an information from HX711, temperature sensor DS18B20 and HTU21D, also check the battery level on 3.7V 18650 after that send through the sigfox information - two temperature, humidyty and battery level. I have done something, but now I have a problem with design of low power, I have to use atmega328P U without arduino board. Is there anybody who can help ( I have almost code ready, last thing I need is hardware and soft solution for battery level check ) I can share code. I also need to discuss my choosen component, if it is good for this application [login to view URL] [login to view URL]:g:vYEAAOSwuQhcTY0D&frcectupt=true [login to view URL]:g:-scAAOSwHMJYFw4-&frcectupt=true [login to view URL]:g:bPMAAOSwYMNano0c&frcectupt=true [login to view URL]:g:vVYAAOxypNtSegO1&frcectupt=true LED and BUTTON best regards Jan

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) Hi. I can help you with low power and battery level measurement. To get lowest power consumption you need to use lowest power down mode with wdt timer( t0,t1 are down in this mode) to generate needed period and cut off power from all sensors and other staff. Power measurement - divide and measure, either by built in adc, or some external. And cut off this measurement line too. Lets talk. Bid is not final due to lack of detailes for now.

Regards, we are a group of engineers in electronics, instrumentation and informatics, and we are interested in helping you in your project. the atmega if you can enter sleep mode but it will not reach the consumption you need, the maximum I have tried in sleep is 320uA, and of course there is a library for consumption to go down much more .... we hope we can help you
