Temperature and humidity thing

Image
The temperature and humidity thing is based on one ESP-01  device. The idea is to have a device, connected to WIFI, broadcasting both values to my web server. Design is not a state-of-the-art, niter software nor hardware. It was designed to be simple and easy to maintain. The hardware The hardware is composed by a mini USB socket (just for power proposes), connected to a step down, regulated to 3.3V. Inside the core there is a small prototype board with some headers soldered, to make removal a less painful. On one the headers there is a dth11 temperature and humidity sensor (I will shortly change it to dht22 for better accuracy). On the other there is a esp8288-01. The software To develop the sketch I've used Arduino IDE. The code is, once again, simple and nothing fancy. I hate having to load a bunch of libruary's, thousand and thousand of code lines just to upload a value to a web server, so I've opted for the old and still useful GET. Main program is

My IOT setup

Image
This is not really my first IOT setup, even before IOT was a reality I've done many home automation. But, considering only now technology is cheap and accessible enough, let's make this as my first useful setup. This is a raw unpolished schema of how I've setup my day to day helpers: On next episode I will try to explain a little more on hardware/software Comment's / questions are welcome.
