Building Rain Guage
The challenge is to measure how much water is falling at the time of rain. The drops of rain vary from place to place as well as the size and density of drops.
The standard model of measuring is to collect fallen rain water in a measuring cylinder. In this model we have manualy remove the fallen rain water from the cylinder. Therefore we need to design an instrument that does not need any human attention.
Rains are measured in milimeters on earth surface using a device known as Rain Guage. So the current challenge in this project is to make a IoT Rain Guage that doesnt need human intervention and measures and sends the data to IoT server. For this automation we could use electronics and communication technologies.
There are various methods and mechanism to measure Rainfall, just go through the below link to know more about it.
Picture shown below is of Tipping Bucket Mechanism Rain Guage.
Challenge 1: Build your own rain guage and complete the followings
Design and build a Tipping Bucket Mechanism for rain guage
Using Mensuration find out the volume of catchment area and also for the buckets.
Connect a sensor to rain guage (you may use magnet and either hall sensor or reed switch)
Use arduino or Raspberry Pi and write a code to measure signal through the sensor and also map it into the rainfall for an hour and a day.
5.Display the reading on Serial Monitor.
Challenge 2: Send Rainfall data to IoT Server.
The pictures shown below displays the readings of Rain Fall through graph on the dashboard created in iot.metastudio.org
- At first use your account credential to log on iot.metastudio.org .
- On Dashboard use graphs and other widgets to display this data.
Report your work done and achievements through pictures, messages and videos.
