I have a arduino water sensor, I want to build a system with my raspberry pie. can anyone give me a hint of steps that i should follow?

I meant to say that to design a circuit of a system which will interact with hardware.

You need ADC which can measure your water sensor analog signal. And ADC can communicate with raspberry pi over SPI or I2C.

Just google "raspberry pi water sensor", internet is full of these basic examples

literally first link i got: https://newbiely.com/tutorials/raspberry-pi/raspberry-pi-water-sensor

or you can talk to your arduino through raspberry pi - usually you can use USB or UART.

but, I would look for esp32 watering project ... esp32 may be much better solution as you can easily control it over wifi and it is cheap

I do have 2 esp32. My goal is to make make project so that i can put it in the resume for embedded engineering jobs they require good skills in micro-processor and controller.

help in that way please. steps to follow that i can do this

you can check my replies here. so can you help me to put things together

Mini , 05-24-2024, 08:08 PM

What do you mean? I just told you what you need and also the link I added literally tells you everything. All the wiring and so on.

I would recommend to use RPI for maybe something more complicated e.g. something with object recognition, object tracking and following etc. RPI is not very suitable for a watering project - it can do it, but it is not a very optimal solution, especially it is unnecessary expensive and power hungry. It means, if your goal is to put this on your resume, it will not show your skill of selecting the best solution for a specific situation. So I would recommend to find a more complicated project for RPI and also maybe connected with fancy topics like AI, object recognition, etc .... That will look much better on your CV. Or you con go to microcontrollers and water sensor project but highlight something like low power, battery powered, etc ...

I agree. Only thing I would think of maybe making raspberry pi as gateway and then running local server on it. There are some really nice GUI out there. For example I have used domoticz in the past. I'm sure there are much better ones nowdays. Also you can integrate with all the home automation.
