Monnit WIT™ Wireless Placement Sensor  

Wireless Placement Sensor

The wireless placement sensor was designed to aid in the placement of wireless sensors. This sensor includes an LED indication system allowing the user to understand the signal strength and quality of a sensors location before mounting. When you no longer need the placement sensor it can be changed to a button sensor through the iMonnit™ online wireless sensors portal.
Monnit WIT Wireless Sensor Specifications
  • 900 MHz Operating Frequency (25 Channels)
  • 300 - 500 ft. Device Range*
  • Replaceable 3.0V Battery
  • At 1 hour heartbeat setting, coin
    cell battery will last ~ 2-4 Years. **
     
  • Manually triggered push button.
  • LED response indicator.
  • Aids in the placement of wireless sensors.
  • Can be reused as a button sensor when no longer needed.

* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting
    frequency and other variables.
