Hello,

I am working on a project that connects a water sensor to a speaker. Once the water sensor goes off I want to send a signal to a speaker about 75/100m away. Could anyone help me figure out the cheapest but still quality way to send this signal?

Welcome to EP!
A length of screened cable would do the job.

A really really simple way to do it is to use an old RC car. The radio would go near the sensor and the car would go with the speaker. Its a kludgy solution though. But it's easyish

This is awesome, thanks! However I'm looking to make this more than once, so I'm needing more of a repeatable solution

Use a wireless doorbell. Cheap as chips. Ready-made. Ranges dependent on the depth of your pockets! But not 'too deep'.....

Interesting, I'll look into this.
How experienced are you with electronics?
Personally I do not have any experience, but I will put the effort into figuring out anything necessary. I'm trying to figure out how to connect a water sensor to a pair of goggles. after the water sensor is under for to long, an alarm will go off outside of the pool

If you are expecting it to transmit from under water, think again.

Of course, you could make an alarm system work without transmitting through the water. You would transmit at a regular interval when not under water, and the receiver would detect no transmission for too long a time and sound the alarm.

Can we get a detailed description of your project? Are you perhaps trying to make a drowning alarm?

This is exactly what we decided to do! Thank you Bob
