Quick Overview

authorized_reseller_badge_1
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.

Monnit Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).

An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 5 years.

  • 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.
