@felmue said in Atom Lite with Earth sensor powered by Tailbat:

If, however, you are open to different hardware you can find boards which are designed specifically for low power consumption.

I chose Atom Lite with Tail Bat because of:

• Out of box solution e.g. board with battery including case.
• It is small and it looks nice.
• Cheap / good price.
• Bunch of sensors which can be easily connected.

I don't know about any other HW which fits these categories. I'm using also other products for home automation which can be on battery for 2 years at least but it is x3 more expensive so I'm kind of surprised with the result :(

Hi @Felix ,

First of all thanks for amazing write up.

Automatic load detection time | TloadD | The load current is continuously less than 45mA | 32s

Oh no that is a bad news for me :) this is kind of important info - I would expect that this is mentioned on m5stack page.

However with the M5Atom TailBat battery of 190mAh that still only gives about 17 hours of operation.

Really nice test thanks. What is your procedure to measure power consumption?

Do you know what is appropriate HW to power on Atom L. for weeks, months on battery ?

Thx

Hi @Pepsi ,

Did you find any way how to achieve it ? I'm looking for something similar but preferably in micropython.

Hello all,

I'm playing with Atom Lite and Earth sensor for measuring of soil resistance.
I'm coding it in micropython as of right now. My idea was to power Atom L. with tailbat and create multiple instances of it for each flower. It should send data few times a day (x 4-6) to MQTT via wifi. But it seems that tailbat can power Atom L. only for short time period (few hours max) :(

Are there any best practices how to achieve best ratio of power consumption ? e.g. some deep sleep ?

Thx
