The Mini-Tilt Sensor is part of the Sensible Living family of wireless sensors. The Sensor uses a tiny mercury switch as a simple non-calibrated Tilt sensor that I use to let me know I have left the garage door open. The module is attached to your role up or tilt up garage door (using the included adhesive Velcro pad). The Mini- Tilt sensor sends a message each time the door opens and closes. Use the delay setting on the desktop app to notify you if it has been open too long. (Note: in the interest of battery life the sensor checks the door status once per minute so it can take up to a minute to respond to the door opening and closing.)
Like the rest of the Sensible Living sensor family it is designed as a low power, battery operated, sensor that sleeps most of the time and wakes up every hour (default setting) and updates its status as well as anytime the door is opened or closed. The Sensible Living Receiver and Desktop application are designed to work with the Mini-Tilt Sensor. The Desktop App can then be configured to send you a message if the door has been left open too long.
From time to time my wife and I have left the garage door open and not notice until the next morning. All of my sensors were built to address specific needs around my home and for my family.
If you are interested in playing with wireless sensors this is an inexpensive and easy way to get started. These sensors are ATTIny85 based. They are a little more difficult to program than their bigger brothers (no monitor or boot loader) but still simple once you get the hang of it. I use the USBTinyISP from Sparkfun ™ to program them and the ATTINY85 (External 8MHZ clock) board package. Contact me for schematics and sketches or for more information.

Retired after 32 years in electrical engineering in Silicon Valley. Starting out in hardware engineering, embedded firmware, systems engineering and engineering management. I have worked for companies ranging from six employees to sixty thousand and managed development programs up to about $60 million. What i'm doing now is way more fun. I started this to learn about Arduino programming and one thing led to another. After building prototypes of these sensors for myself and some friends I decided to see if anyone else could use them. With a little luck I will make enough to buy a new scope. My old one still works but it was a discard when I got it 30 years ago and it takes a while for the tubes to warm up. :-)
I got the Rigol DS1102E. I love it! Just what I needed to develop and test my IOT sensor projects
