so for my school science exhibition, i've been assigned to make a smart irrigation system using rainwater harvesting and solar energy, something like the model in the attached picture. the idea is to collect rainwater from rooftops, store it in a tank, and use a soil moisture sensor to automatically turn the water pump on when the soil is dry and turn it off when it's wet enough.

the thing is, ik absolutely nothing about electronics rn. i understand the basic concept and what the model is supposed to do, but i have no idea how to connect everything and make it work. i can't just make a model that looks good but doesn't actually function, so i'm trying to figure out how to build the entire thing.

these are the components i've been told to use:

- soil moisture sensor x1

- automatic pump controller compatible with the sensor x1

- mini dc water pump x1

- solar panel x1

- compatible rechargeable battery x1

- solar charge controller, if required x1

- connecting wires

- switch x1

- suitable fuse and holder x1

i have a few questions and would really appreciate some guidance.

1. how do i connect all these components? i need the complete circuit diagram, including the solar panel, battery, sensor, controller and pump, with labelled connections so i can understand what goes where.

2. what specifications should i look for in these components? like what voltage should the solar panel, battery and pump be, and how do i make sure everything is compatible?

3. how does the automatic mechanism actually work? ik the sensor detects moisture, but how does that signal reach the controller and make the pump turn on or off? do i need an additional relay, or can the automatic pump controller handle that itself?

4. how do i connect the solar panel, battery and charge controller? is the battery necessary, and how do i make sure the pump gets enough power?

5. how do i connect the rainwater collection system, storage tank, pump and drip irrigation pipes so the water actually reaches the plants?

6. are there any other components or materials i'll need apart from the ones listed above?

7. since i'm a complete beginner, what should i build and test first? i don't want to connect everything at once and have no clue what went wrong if it doesn't work.

i'm in class 11, and this is for my school science exhibition, so i need something affordable and practical that i can actually build and demonstrate. i'd really appreciate explanations in beginner-friendly language because most of the electronics terminology is completely new to me.

i'd especially appreciate a proper circuit diagram and specific component recommendations rather than just a general explanation of how smart irrigation works. if there's a simpler or more reliable way to build this while keeping the same concept, i'm open to that too.

also, which subreddits would be best for getting help with the actual circuit and wiring?

tl;dr: i've been assigned a smart irrigation model using rainwater harvesting, a soil moisture sensor, an automatic water pump and solar energy for my class 11 science exhibition. ik nothing about electronics, so i need help with the complete circuit diagram, compatible components, wiring and how to build a working prototype from scratch, used chatgpt for grammar correction and structuring the post, but questions are mine.

My parents want me to score atleast 98%, but idk if that's possible or not. I'm ready to put in the hardwork, so seniors please give some advice.

Bhai iupac ke according 5 carbon ki main chain mani jaegi aur teesre carbon pe 2 substituents hai, ek methyl aur ek complex substituent bromomethyl

Aur complex substituent ka nam bracket me likha jata hai

To correct nam toh upar wala hona chahiye

Lekin ncert me niche wala nam diya hai, unhone jis carbon se halogen attached hai usko main chain me Gina hai, aur main chain 4 carbon ki bana di hai

But naming ka first step hota ki longest c chain hi main chain bnegi

Multiple bonds aur functional group agar compound me hai toh use toh mainchain me include krte hai

But yaha aisa bhi kuch nhi hai

So is this a Error in ncert?

Imo isnt this system kinda unfair cuz the whole class 10th is all about definition mug ups?

I got like 60% in my Pre Mid Terms and 62% on my Midterms.

I have wasted too much of my time. Half a year is already gone but I don't want to waste any more time. The way i studied was to start studying a week or 2 before the exams. Now I have started to study seriously by watching one shot and solving modules. Only my physics and chemistry are bad I have managed to get good marks in Bio and others. The way i have started is by starting to make notes from ch 1 of both physics and chemistry, I did bio from the start so I think I am okay with that. Pls suggest any tips.

Every night: Kal se pakka padhunga.

Every morning: Aaj thoda rest kar leta hoon, kal fresh mind se padhunga.

Every evening: Ab toh kaafi late ho gaya, kal properly start karunga.

And somehow I'm still convinced that one magical Monday will change my entire life. ❤️

Since when did cbse start releasing 5 sample papers each year 🥀I wanted to do pyqs but these mfs are forcing me to buy sample papers 😭

I have taken part in science exhibition. Me and my friend have decided to do something related to physics. Can you please recommend some ideas about what to do

Will ai background changed image be allowed by cbse? The image is taken by phone and nothing is changed except for the background.

Till now, I haven't studied properly and only did to pass off exams.

Is it possible to score 90% now? Like I won't go to school, and will have very much time.

Sometimes even if I know answers, I can't write fast enough to cover everything.

Also, where do you guys take notes from? Is it necessary?

Sorry for the dumb questions, because I am dumb.

One more, will I be fine if just complete ncert? or would I have to buy one of QB or SP?

Hi everyone, I passed Class 10 through ICSE in 2020. I failed Class 12 CBSE in 2022 and later completed Class 12 through NIOS in 2023.

I have my Class 10 ICSE and Class 12 NIOS marksheets, but I don't have my Class 11 marksheet. I'm concerned about the three-year gap between my Class 10 and Class 12 completion years.

Will my Class 11 marksheet be required during campus placements, off-campus recruitment, or government job document verification? Could my previous failure, academic gap, or missing marksheet cause any issues with my future employment?

I'd appreciate genuine advice, especially from people who have faced similar situations. Thanks!

Guys, can you please give me your views on the issues you face the most but no one provides solutions to. Give it all here,

Be it time management or distractions, Mental health can be an example!! Or too much content on plate, so curation might be an issue!!

I know there are already infinite number of coachings and apps trying sell you subscriptions. I am not here to sell from that, but from edtech only (working with schools). I have also been in Kota for 2 years and then studied from an IIT only not.

I just received my pre board 1 time table which is on 17 November so rn I have exactly one months to finish the syllabus for pb1 or 60-70% syllabus at the very least.

I am basically on 0% btw

My subject are Maths physics chemistry english hindi and PE

Hey everyone!

I recently completed a full revision book/notes set covering the entire Class 10 CBSE Chemistry syllabus.

What’s included in the notes:

• Chapter-wise summaries covering all key topics (Chemical Reactions, Acids & Bases, Metals/Non-Metals, Carbon Compounds)
• Clear definitions, essential chemical equations, and reaction mechanisms
• High-yield revision points tailored for board exam preparation
• Clean formatting for quick last-minute revision

I’m planning to release the complete edition soon at a very affordable price for fellow students.

If you are interested in grabbing a copy or would like to see a free sample chapter/preview PDF, please comment below or send me a DM!

Any feedback from fellow Class 10/11 students on what you usually look for in good Chemistry notes would also be super helpful. Thanks!

i am thinking to make short notes while revesion of long notes par likhu kya mujhe to saB kuch imp lagra h T-T

fml chlo kam se kam pass to hun

Isn’t the Boards 2027 date sheet taking forever this year? We’re already mid-October and there’s still no sign of even a tentative one. Last year for the 2026 boards they dropped the tentative schedule by 24 September and the final one on 30 October. This time it’s dragging way more than usual. Feels like they’re making us wait longer than previous batches for no reason. Any thoughts on this?
