Bee in a box

So how long will the 800mah Lipo last - hours, days, weeks or months?

nNode with a RFM95 Lora Bee sending Temp, Humidity, and Pressure from a BME280 every 5mins


At least days until you go and open the box to make sure it’s still there :slight_smile:

Nah man, it uses mythical radio wave white man’s Lora magic to give me the numbers so I don’t have to open the box.

I pick months for the battery.

Are you putting the BME280 into standby mode during those intervals? There are no leds or other current hungry devices on it right?

I’d say 6 weeks.

Its all off while sleeping so drawing 40nA for most of the time.
