AutoWats - A Plant in Every Home!

Opps! Didn't realise that the pipe connection broke...Apology!

I didn't use the 3d printed case due to the size of it. The soil moisture sensor wasn't fitting inside it.

AutoWats LCD + APP working DEMO:

1. I'll be putting Planti in one of those cases you see in the right.

2. I''ll also be using one of those 2 solar panels.

3. I did not use the ESP8266 module for the time being and instead used the HC-06 bluetooth module....I Can also use the ESP module.....but due to lack of time whivh was caudes by the late arrival of my order.....I didn't get time to instlall, flast and uodate the firmware of ESP module....I'll surely be using ESP in the FUTURE UPDATATES...thanks a tonne all ...LUV U ALL 'MAKERS' and 'HACKERS'.

4. I have add a protection to Tapo for increasing it's durability.

*There was an error in the app and the 'Soil Stats' label wasn't getting updated...I have fixed the error in my latest apk ...you can download it in the files section

-Apology
