# What Is the Urine Sensor and How Does It Work
## A smarter way to know when it’s time to empty—built into every OGO™ ORIGIN Compost Toilet System.
No one wants to guess when the urine bottle is full. That’s why every OGO™ ORIGIN Compost Toilet includes a built-in liquid level sensor—**so you never deal with unexpected overflows or messy surprises.**
Here’s how it works, why it matters, and how we’ve designed it to stay reliable—no matter where you take it.
---
### Precision-Engineered for Real Use
Each OGO™ urine sensor is mounted to a **custom bracket** inside the toilet, measured and placed at the exact height needed to detect when the bottle is almost full—giving you a heads-up before it’s too late.
- **Made from HDPE plastic** for strength and durability
- **Secured with stainless steel screws** that hold firm even in mobile setups
- **Designed for tight fit**—no wobbling, no shifting, even on bumpy roads
Every unit is **hand-assembled in Ohio**, and each sensor bracket is inspected for proper alignment and distance from the bottle. Quality control is non-negotiable—this part has to work, every time.
---
### Built to Withstand the Ride
Whether you're hitting backroads, off-roading, or just navigating tight turns in an RV, the sensor bracket is engineered to stay put. It holds the sensor securely in place to maintain accuracy trip after trip.
If you ever need to clean it, a simple wipe or swab is all you need. Avoid spraying directly—just use a damp cloth or towel to clear away any buildup.
---
### What If You Don’t Want to Use a Bottle
We get it. Some lifestyles call for **zero bottle maintenance**, especially in long-term or permanent installs.
That’s why we offer the [**OGO™ Drain Kit**](https://ogotoilet.com/products/drain-kit-2)—a plug-and-play upgrade that diverts urine directly into an existing tank or greywater system.
- **Includes**: a molded base, flange, stainless steel hardware, and cut-to-fit PVC
- **Fits standard ¾” piping** and most common hose fixtures
- **Fully removable** for cleaning, moving, or switching back to the bottle
Like the rest of the OGO™ system, it’s built strong and simple—so you can set it up once and forget about it.
---
### Final Word
The OGO™ urine sensor was designed for one reason: to make your life easier. No guessing. No mess. Just a clean signal when it’s time to empty the bottle.
And if bottles aren’t your thing? We’ve got you covered there, too.
**Smarter features. Better flexibility. Built for real life, wherever you go.**
