ESP Board and Power via Battery

#1 Post by popperchris » 23 Aug 2019, 09:45

Hi all
i use a ESP Board to Masure Temp, Humidity and Air pressure.

The Place to use a Power Supply is not a Good Place. The sun shines directly on the ESP board in the morning. A good Place is without Power.

Use a power bank from you and can share with me experience how long it lasts before it needs to be loaded!!

Thanks
Christoph

Re: ESP Board and Power via Akku

What's an Akku ????

Is it possible to put the ESP board in the shade and power it from a solar panel ???

One of my students has made a solar-powered weather station using a Wemos D1 Mini (ESP8266 running ESP-Easy).
He puts the board to sleep for 15-minutes (to save energy), then when it wakes up it takes some measurements and publishes them to Node-RED via MQTT, then goes to sleep.

If you want to try running it off of a powerbank then the time it will last depends on the mAh capacity of the powerbank.

Before he decided on using a solar panel he tried a powerbank and it only lasted 2 or 3 days before it needed charging.

Hope this helps.

PS: I can send you links to the solar-powered weather station if you are interested.

An "Akku" is probably German for "battery". :)

If heat, or temperature in general, is an issue. Then you should for sure not start using batteries.
That's a fire hazard waiting to happen.

You've probably seen temperature protection kicking in on a smart phone or car navigation. Those are there for a very good reason.

still, common in German is a battery but when saying 'Akku' (Akkumulator) we mean a rechargeable one.
@ dynamicdave: I woud like to see your links for the solar-powered weather station, especially for the rules.

Here's the link to the project on Discourse Node-RED.

https://discourse.nodered.org/t/solar-p ... n/12499/73

The project was split into six managable stages.

I hope you find this useful.

In Dutch we also use "accu" for rechargeable ones.
But sadly the word "battery" and "accu" are very often mixed in conversations in Dutch.
