The minimum temperature that can be read by the sensor is -40°C (-40°F), so if a low temperature alarm is not required it is
recommended that this be set to -41°C. Any temperature entered lower than -41°C will be set to -41°C.
Factory default for this setting is 0°C.
Humidity High Alarm
Enter an integer value for the humidity that when exceeded will cause a humidity alarm. In alarm, an email be sent if
configured to do so, and the humidity measurements on the home page of the Neon webserver will be shown with a red
background.
The maximum humidity that can be read by the sensor is 100%RH. If a high humidity alarm is not required it is
recommended that this be set to 101%RH (such an impossible value is deliberately permitted so that the alarm may be
disabled). Any humidity entered greater than 101%RH will be set to 101%RH.
Factory default for this setting is 80%RH.
Humidity Low Alarm
Enter an integer value for the humidity that when exceeded will cause a humidity alarm. In alarm, an email be sent if
configured to do so, and the humidity measurements on the home page of the Neon webserver will be shown with a red
background.
The minimum humidity that can be read by the sensor is 0%RH. If a low humidity alarm is not required it is recommended
that this be set to 101%RH (such an impossible value is deliberately permitted so that the alarm may be disabled). Any
humidity entered greater less than -1% will be set to -1%RH.
Factory default for this setting is 20%RH.
Alarms Page
This page is used to configure the events which will generate an email from the Neon, the email subject header, importance
and recipient.
The Neon 100 comes with its own pre-configured email account, so there are no email account administration settings to
enter. Email will always be sent from [email protected].
The Neon 110 allows the user to enter their own SNTP settings which is done using the email page of the web interface.
Email from a Neon 110 will always be sent from the user configured email account.
Settings are applied as soon as they are saved. There is no requirement to reboot the unit for new settings to take effect.
An easy way to test that emails are working is to enable the power fail alarm once the email subject and address has been
set up, and then to cycle power to the unit. Please remember to save the changes before doing this!
All alarm emails from the Neon will include the unit’s name, serial number, date, time, and current temperature and
humidity measurements.
Important:
Please make sure that [email protected] (for Neon 100) or the email address entered on the
email page (for Neon 110) is added to the recipients email client as a trusted email address so that any email is not
trapped by spam or junk email filters.
Important:
The Neon can only send one email at a time. If there is a network problem that prevents sending of email, the
Neon will re-try until the email is sent. However, if a new event (alarm or log) causes another email to be sent, this will over-
write the email in the send buffer which will be lost. If power to the unit is lost with an email pending to be sent, that email
will be lost.
