Wio Node

Wio Link now has got a little brother – the Wio Node. Two samples arrived from SeeedStudio today. Have a look to SeeedStudio’s images and compare:


Wio Link-1

Wio Node has the most of features as Wio Link. But it is cheaper, smaller and also lighter in weight.

  • An ESP8266 based open-source Wi-Fi development board (here Espressif’s WROOM-02 is used)
  • Supports Grove Sensors/Actors
  • Visual Configuration via Mobile App (Android & iOS)
  • OTA (Over-The-Air) Firmware Updates
  • RESTful APIs
  • IFTTT Application
  • Powering by Micro USB
  • Battery Holder for re-chargeble LiPo accu

Easy starting at iot.seeed.cc/start.

already little sun helps…

The following images show that already little sun as today helps to recharge the LiPo accu of the solar-powered AM2315 sensor.

As you can see, for mid of May it is a little bit cold. After noon, the clouds thinned slightly and the temperature grows up. The IP camera image shows the cloudy sky.

But, the prognosis for the afternoon is not so bad. Look at the evening what happened.

Today the test unit stopped again with a LiPo accu  voltage of 2.04 V. Recharging was needed.

This test started at May, 2nd and was running 14 days. We had no good weather conditions, but the run time was below expectations. After recharging  the LiPo accu the test will be started on another location. The recharging occurs inside therefore you will see room temperature for this period in the graph. Restart at 2016-05-17 9:00.

After recharging the LiPo akku over the last night I started the test again. I increased the sleep time to 10 minutes to get better compare to a test before. This test was documented at https://drive.google.com/drive/folders/0BwUOc1bstFZ9Zm1JbUlORDNua2s. Under these conditions I got a runtime of 48 days from February to April.

You can follow the measuring results at http://www.ckuehnel.ch/AM2315@NODEMCU.html again.

I added a weather widget from kachelmannwetter.com to see the correlation between weather situation (means sun) and the voltage of the LiPo akku.
