This project uses an ESP8266 and an analog Capacitive Soil Sensor to alert a user of it's plant health
This repo uses the universal-telegram-bot-library as a basis for sending messages using a Telegram Bot, need to have that installed first.
Also a Telegram Bot is needed, for that we use Telegram and by messaging BotFather with the /newbot command. From there we can name our bot and add a profile picture for it. After that BotFather will give us the Access Token for that Bot in the following form XXXXXXXXX:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX. Take note of it and do not share it with anyone.
For our own Telegram user we need to grab our ID, and for that we message UserInfoBot with the /start command. Save the 9-Digit ID for later
