1. Before linking your sensor, make sure Bluetooth® is turned ON! For Android devices you will also need to turn Location Services ON which Android requires when linking to Low Energy Bluetooth devices. Lastly, make sure you have an internet connection.

2. Open the Humiditrak App and then from the My Instruments screen select the + button in the upper right hand corner.

3. When prompted, remove the plastic pull tab from your sensor and follow the on-screen instructions. If you have previously removed the tab before linking the sensor, remove the battery cover on the Humiditrak sensor or rotate and separate the cover on the Safe & Sound sensor, remove the battery from the unit, then re-insert the battery and covers. When the plastic tab is removed or the battery re-inserted, make sure the sensor blinks red 4 times. This red LED can be seen through the slits on the front of the sensor.


IMPORTANT - Before removing the tab or re-inserting the battery, make sure all other sensors are at least 10 feet away from the sensor you are linking.
