Monnit Wireless-Light-Detection-Sensors


Product Description

Monnit wireless light detection sensors can be used to detect whether light is present or not. The sensors can be user calibrated for baselines of light and dark, and will provide a status of light presence based on those baselines. Alerts can then be setup for when light has been detected or when there is no light detected.

Product Features

  • Sense the presence of light.
  • Know if the lights have been left on at your facility.
  • Know when light bulbs have blown and need to be replaced.
