ProCodeCG – Private Training – Data Acquisition with ESPectro – Day #2 – 17 May 2017

Private training on gathering data from sensors using DHT11 and MLX90614 using ESPectro development board Day #2 🙂

It is time for hands-on 🙂

The first thing to try was connecting MLX90614 to ESPectro and show the sensor readings to serial monitor

Yep, it worked 🙂

Next was trying to connect a LCD I2C to an Arduino Mega 😀 The client said she wanted to display it on LCD, since she had this Arduino Mega, she wanted to test it 🙂

The port connected Arduino Mega wasn’t detected

But when we connected it to a Mac, it worked. So we have to install specific driver for Arduino Mega USB on Windows

Moved to DHT11, and connected it to ESPectro

One DHT11 worked

Adding more DHT11

and worked

The temperature read by  both DHT11 looks similar but there was a significant different on humidity

Now try the multiple DHT11 with Arduino

Worked but the second sensor reading was showing impossible values, which worked just fine with ESPectro. Need to debug this later!

Then we learned some Python to read serial monitor and save it to a file (.txt, .csv, .xls)

Like this, so then the data can be processed and analyzed 🙂
