Protect employee wellness & productivity

As Carbon Dioxide (CO2) concentrations rise within facilities, occupants may suffer from fatigue; excessive exposure triggers nausea and/or vomiting. Monnit’s Enterprise Carbon Dioxide Wireless Sensor monitors this gas; if levels exceed preset limits, designated personnel are alerted via text, email, or call.

The Wireless Carbon Dioxide Sensor uses an ultra low-power, high-performance CO2 sensor to measure the amount of carbon dioxide in ambient air. It is programmed to take readings at a set interval to accurately calculate CO2 levels, then send the time-stamped data to the iMonnit Online Sensor Monitoring and Notification System at user-specified time intervals (sensor heartbeat). The CO2 data can be reviewed and exported as a data sheet or graph and notifications can be set up through the online system to alert the user when defined thresholds have been met or exceeded.

Sensor features:

• Measures 0–10000 ppm
• AA-battery powered (10+ year battery life)
• Instantaneous CO2 readings & 8-hour, time-weighted average readings
• Options: on/off switch or line-power with battery backup and on/off switch

Additional features

• Impressive wireless range of up to 1,200 feet through walls
• Frequency-hopping spread spectrum (FHSS)
• Improved interference immunity
• Improved power management for longer battery life
• Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
• Over-the-air updates
• Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email
• Stores 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power cycle)
  • 10-minute heartbeats = ~ 22 days
  • 2-hour heartbeats = ~ 266 days

Applications

• Indoor air quality
• Marine Vessels
• Grow houses
• Ventilation Management
• Cellar and gas stores
• Modified atmospheres
• Confined spaces

* Please take care when connecting a power device.
** ΔP is in mbar and is the difference between atmospheric pressure at sea level (1013 mbar) and the pressure at the sensors altitude (Ex: 1013mbar – ambient pressure in mbar).
*** For correct autocalibration, the sensor must experience fresh air CO2 levels (~400 ppm) for at least 4 hours per day. If the environment does not meet this criteria then disable the autocalibration feature.
