Monnit Industrial Light Sensor

Monnit's industrial wireless light sensor detects the presence of light and returns a value of light or no-light to the system. This sensor can be used to alert when lights are left on or can be used to determine if cargo has been opened. Alerts can be set to notify the user via SMS text or email if the sensor detects light with the ability to only notify within time of day parameters.
Monnit Industrial WIT Wireless Sensor Specifications
  • 900, 868 and 433MHz operating frequencies
  • External 2dBi or 3dBi RP SMA antenna (included)
  • 300 - 350 ft. non-line-of-sight device range*
  • Up to 5 year battery life.**
    (Replaceable, single AA, 2500mAH, 3.6V battery)
  • Operating temperature: -40° to 85°C (-40° to 185°F)

Monnit Industrial Sensors with Solar Power Option

Need Longer Battery Life?

Monnit Industrial Wireless Sensors are also available with a solar power cell. The solar powered sensors use 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.

  • Keeps battery charged and at optimal capacity
  • Extends the life of the included rechargable battery
  • Great for outdoor monitoring
