I am a pupil at Roedean School SA. Our class has been assigned a project to make an electronic circuit. I have an idea but I am extremely unsure if it is going to work as it requires to the circuit to be wireless. There would be two circuits one with a water sensor that when wet will sound a buzzer on the other circuit. Please please help !!! Does this make sense and if so… please help me to design the circuits and what components I would need.
Hi Franki
Yes it does make sense and you just need a little help form EG's side. Check out these links which will help you build your own circuit:
1. "engineersgarage.com/electronic-circuits/soil-moisture-detector"
2. "engineersgarage.com/electronic-components/rf-module-transmitter-receiver"
You can use the former link to detect presence of water, then make use of 2nd link and transmit data wirelessly over RF. RF's transmitter will be present at the water detection circuit while it's receiver will be linked to the circuit having buzzer.
Although I have not told you what exactly needs to be done, these links will surely help you understand the concept and come up with your own unique way of doing the same.
Good luck
simple sensor you can make with the help of IC NE555
give its output to arduino. and arduino sends this output to another arduino with buzzer using RF Tx and Rx modules
