A simple Telegram Bot that lets users know the temperature,humidity using DHT11 Sensor and notifies users if it's raining using rain sensor. Ask the bot if it's a good time to wash/dry clothes. Use it already !! :umbrella:

What does it do 👂

Basically, tempSense is a Telegram Bot that can get us the temperature(in Celsius or Fahreneit),humidity when we ask for it. You can ask this bot whether it's a good time to dry out clothes and it will also send notifications if it starts raining and will caution you to remove clothes if such an event happens. This is my first ever IoT project and I have only started to explore this field and there is a lot more to learn as of now. So this project is simple but useful as well.

Components Used

• NodeMCU
• DHT11 sensor
• Rain sensor
• Jumper Cables
• B-Type USB Cable

How was it built?

I tried two approaches for building the bot.

• Using telegram bot libraries for nodeMCU and also collecting the sensor values as well
• Collecting sensor values and posting it to a webserver hosted using nodeMCU and also building a server for telegram using node.js which will get these values from the esp webserver

Approx Cost

• DHT 11 sensor - 100-200 Rs
• Rain Sensor - 100-200 Rs
• NodeMCU with ESP8266-12E module - 300-400 Rs
• Jumper Cables(bulk)- 100-200 Rs
• USB B-Type Cable - 300-400 Rs(you can use your charging cable as well if you have B-Type Cable
