Real-Time Sensors Inside Homes

  1. Find a convenient location to set up the monitor where it can be plugged into a wall outlet or to a power strip. The monitor should ideally be set up in the breathing zone (~5ft above the floor) but should also be set up out of reach of small children or pets. Ensure that the inlet and exhaust remain unobstructed. The package can be mounted via zip ties or can be placed on a shelf or other surface.

  2. Once sensor is plugged in make sure the LED is on solid (except flicker-flashes every one-minute indicating data logging)
  3. If LED is not solid, ensure the SD is properly inserted and try unplugging the sensor from the power source (battery or wall) and reconnecting.

Real-Time Sensors Outside of Homes

  1. Select a location for the monitor based on the list of preferences below:
    • On same level as residence (e.g. balcony)
    • On roof
    • On ground floor (e.g. fence, guard station, etc.) • This is preferable if the residence is significantly closer to the ground floor than to the roof.
    • Nearby accessible location (e.g. university building)
    • Use a close by monitor outside a neighboring home
  2. Ensure the monitor is secured using zip ties and avoid situations where monitors could fall multiple stories if they become detached.
  3. Use wall power if readily available otherwise plug in battery.

Factors to consider when selecting deployment location:

  1. Security and safety if instrument were to become detached (do not hang out window)
  2. Ease of access to replace battery every 2-3 days
  3. Possible theft or tampering with devices if they are easily accessible to the public
