ProCodeCG – Private Training – Data Acquisition with ESPectro – Day #1 – 15 May 2017

Standard

Today we had a training on gathering data from sensors using DHT11 and MLX90614 using ESPectro development board πŸ™‚

Setting up before the class started

IMG_8921 IMG_8922

IMG_8923

We used two different computers to make sure we can do lots of things simultaneously πŸ™‚

IMG_8924

we also have to make sure we have reliable internet connection and a toolbox full of anything we might need πŸ˜‰

IMG_8925

we tested MLX90614 with Arduino

IMG_8927

IMG_8929

and it worked. Next we will use ESPectro to be able to send the data via cloud πŸ™‚

IMG_8928

We’re going to use the sensors to measure battery temperature

IMG_8930

We’re going to use multiple sensors to measure multiple batteries, so we’ve got lots of things to do, and will continue the training on Wednesday πŸ™‚

We took a picture
IMG_3706

And start tinkering with DyCodeX ESPectro Core πŸ™‚ The driver worked just fine on Martin’s laptop.
IMG_3708

But most of our students Windows laptop won’t install the driver automatically
IMG_3710

So we had to go here andΒ tofind the driver

IMG_3711

After we got the driver then we discuss about the GPIO and other stuff
IMG_3712

We had problems with reading the layout and need some clarification about the devboard design

IMG_3713

It was just the right decision to have a meeting with DyCodeX while having Geeknesia CEO around. We discussed super important things about IoT
