Keep the trap you already use.
Each sensor comes with a clip for common wooden snap traps and a zip-tie mount for other setups. The mount sits below the trap without replacing its mechanism.
Why Mouse Minder exists
I was tired of checking empty traps.
After a Christmas trip, I came home to a mouse that had been sitting in a garage trap far too long. I did not need a smarter trap. I needed the traps I already owned to tell me when they had fired.
One piezo does two jobs.
The piezo element senses the sharp vibration when a trap fires. Then the same part becomes the speaker while an LED flashes. Short alerts stretch the coin cell instead of wasting power between events.
Open source for other jobs.
The sensor design and enclosure files are published on GitHub, so makers can adapt Mouse Minder for specific jobs beyond mousetraps—like door-open alerts or animal-tamper sensors.
