The Mini Wireless Temperature and Humidity Sensor by tempi.fi records a new reading every minute and sends alerts directly to your phone. BE ALERTED RIGHT AWAY Whether your are monitoring your backup freezer, a baby's room, or the temperature in your doghouse, you need to be made aware of any temperature or humidity problems before its too late. This sensor sends alerts directly to your phone. You can set high or low temperature and humidity alerts and will receive a notification when the temperature or humidity crosses the thresholds, allowing you to take control of the situation, make necessary adjustments, and mitigate damage. Not in range when the alert occurs? No problem. If you are out of range when the sensor triggers an alert, you will get the alert on your phone when you come back into range. Read more WIDE RANGE OF OPERATION This sensor has a theoretical range of 300ft in a space with no obstacles in its path. Its typical range is between 60 – 120ft., depending on various factors, such as piping and the type of wall material. As long as you are within range, the sensor will have no problems transmitting data to your electronic device. Out of range? No problem, get sync your data and get alerts you missed when you get back into range. In a modern 3,000 square foot home, the sensor can usually be detected in any room. Soon, a WiFi gateway (sold separately) will also be made available, allowing you to get real-time readings on your smartphone from anywhere in the world. Read more FOR LARGE TO SMALL APPLICATIONS This mini wireless sensor can fit just about anywhere. Whether you are placing it in the back of your freezer, a cigar humidor, or a wine cooler, you shouldn't have a problem placing the 1.57" x 1.57" x 0.65" sensor (40 x 40 x 16.5mm). The sensor is not waterproof because it has a humidity component that needs to be directly exposed to the environment. The sensor can be used outside if it is protected from water, rain, and snow. Read more OPERATES ON A SINGLE BATTERY FOR OVER A YEAR This mini wireless temperature sensor is built to operate 24/7 indoors or outdoors. If placed outside, it is best to keep it in an airtight ziplock bag to protect against water, rain, or snow. Don’t worry, even inside a protective bag the sensor should still report an accurate temperature reading. The device relies on a CR2477 coin cell battery (included in the package), which should provide power to the sensor for more than a year. LEVERAGE THE POWER OF UNLIMITED DATA The downloadable app is designed to automatically keep an unlimited, minute-by-minute history of its temperature and humidity readings. You may export and generate the entire history - or just parts of it - as a CSV file, which you may open in Microsoft Excel or Google Sheets. Discover patterns and pore over years of temperature-reading history through the app's interactive and intuitive graphs. PRESERVE YOUR BELONGINGS High levels of humidity can easily cause wooden furniture, instruments, and flooring to warp, bend, or crack. This wireless sensor is a must-have if you keep antique pieces, musical instruments, or art collections in your home. Keep a temperature sensor inside your instrument cases, in your home art gallery, or your antique furniture showroom to stay updated on room temperature readings.
