Suggest me 2 sensors / idea for each category for which arduino ide has inbuilt library

Projects General Guidance
1
  1. Rain sensor (No Idea) /Weather API?
  2. Temp / Humidity / Atmospheric pressure sensors (Must be able to calculate all )
  3. Light sensor (Lux level for which library available in arduino ide)
  4. Position control motor (Sensor) and any motor to open / close the valve --Suggestion in this is
    extremely required (for motor)
  5. Battery level monitoring (For measuring an AC 220 battery level)
  6. Water / Liquid level sensor (For which library is available in arduino ide)

HI,
What is your project?

What have you found in your investigation?

Have you Googled;

arduino humidity and temperature sensor

arduino light sensor

arduino Water / Liquid level sensor

arduino Battery level monitoring

And researched for a library for the results?

Tom... :smiley: :+1: :coffee: :australia:

Hi i found some sensors , like for temp / hum/ pressure as BMP280

Battery level not priority , but for Light sensor and water level sensor/ transducer i need suggestion , bz i have very less time to finish the project.

So , some shortcuts i ll have to take , i will be thankful if you suggest some --- if for any of these two sensors i can get the libraies.

Its all about time constraint , i hope you understand my situation

In my last project , i used a chinese water level sensor - CSPPM 127 and bad thing was - The read / write commands were wrong in their manufacturer datasheet and it was a deadly kick from them to me , but i survived anyhow. This time i am being cautious about these and wanted to use a well known sensor andavailable in market in which it will be easy to read data

BME280 give you temperature, pressure and humidity
water level - depends on environment and distance - I have used

  1. Waterproof JSN-SR04T Ultrasonic Distance Sensor
  2. Pololu TOF sensors

what is the application?

Is this a school project?
Why only a little time to finish?

Hello prateeks907

Take this advice to get ready in time.
Follow the example code that comes with the library or
run some tutorials for the hardware selected.
If you are happy with the results of the tutorials you can merge these to your project.

Have a nice day and enjoy coding in C++.

It will be a water tank collecting the water for big roof drainages. Tank may be of 10000 to 50000 litres. Please suggest as per this application

For winning project , people can do anything , even crush their own people. I hope you understand

To awoid getting crushed, no further questions. Not my game.

What is the task of this application?

12

In our application , we are going to measure the water level of near 5-20 mtrs . and pressure transducers are indirect ways of measurement . Is there any sensor existing having direct water level measurement up to 10 / 20 mts . This would be a tank

13

never dealt with a tank that large
10metres is certainly possible, e.g. XL‑MaxSonar‑WR Products
maybe worth contacting some manufacturers
