IOT Micro Weather Station: Temperature and Humidity module

Simple and Easy IOT Project

As soon as you learn to measure temperature and humidity, please report to us. We will grant you a badge and then create an account on our IoT Server.

Challenge 1: Measure Temperature and Humidity.

The pictures shown below has used one of the available sensors to measure the temperature and humidity of our surroundings and displays the readings on the serial monitor of Arduino.

Connect the sensor to arduino, also complete and report the following challenges:

  1. Write a program to measure the temperature & humidity and display their readings on serial monitor of Arduino IDE.

  2. Give variable temperature and humidity input to the sensor: e.g. by breathing out on the sensor. This is the first test your device must pass.

  3. Add some rule: Connect a buzzer to Arduino board and add program to generate a beep whenever the temperature goes above a specified temperature.

Please Note you can use Arduino, Raspberry Pi or any other microcomputing platform (Arduino is preferable due to its low cost and easy to operate).

To know more about Arduino and raspberry pi (microcomputing platforms) visit the following links:

Once you are done with all the above task,s report your work done via photos, videos, messages, etc. Then our Referees will grant the first tinkering badge, which is eligibility for obtaining an IoT account. Without an IoT account, you will not be able to complete Task 2.

Challenges 2: WiFi Communication Interface of your weather station

  • Connect an ESP-01 (a WiFi module) to Arduino ( to the setup you did in Task 1) to establish a communication interface to the weather station.
  • Write a program to complete the following challenge:
  1. To connect your ESP-01 to hotspot or WiFi to access the Internet .

  2. After a successful internet connection, establish a connection with iot.metastudio.org and send your temperature and humidity data to your dashboard.

Challenge 3: Send Temperature and Humidity data to https://iot.metastudio.org

The pictures shown below are visualizing the readings of Temperature and Humidity through graphs respectively on the dashboard created in iot.metastudio.org

  • At first use your account credential to create a Dashboard and a Device on iot.metastudio.org.
  • On Dashboard use graphs and other widgets for visualizing the data.

Report your work done and achievements through pictures, messages and videos.

While you are making whatever questions you have, whenever you need help, do not hesitate to ask by replying to this topic.

This project depending on your experience may take from 3 days to 2 weeks.
