Vivarium Monitoring

This fellow is a new addition to our household:



We have a new vivarium for him and I wanted to be able to monitor the temperature inside from anywhere. I was thinking of using MQTT and Thingspeak, but a quick search came up with BLYNK!

Blynk is an app that is easy to link to with Arduino / ESP8266. The device sends data to Blynk's server and the app is SO easy to set up and display the data in graphical and text form.

I used info and code from these sources and adapted them to suit.

My code can be found here:

I have a Heltec ESP8266 with OLED display.

I may change this as I want the project to be battery powered.
