KWJ -WSN CO Quick Start Manual

KWJ-WSN CO
Wireless Carbon Monoxide Sensor
Technical Overview
General Description
KWJ's WSN CO detects ambient Carbon Monoxide levels
from 0 - 1,000 ppm in ambient air and transmits the data
wirelessly to the KWJ-WSN Dashboard. KWJ-WSN CO
delivers low level health monitoring not provided by other
off the shelf CO detectors.
Features
• Measures CO up to 1,000 ppm.
• High Accuracy (± 5%)
• Advanced Printed Electrochemical Sensor
Technology
• Long Life/Low Power Battery Operation
• Free KWJ-WSN basic online wireless sensor moni-
toring and notification system to configure sensors,
view data and set alerts via SMS text and email.
Principle of Operation
Electrochemical CO, Ambient Diffusion
15 minutes after the battery is installed, the sensor will
accurately measure the ambient CO level and send data
to the KWJ-WSN Online Sensor Monitoring and Notifi-
cation System. The data is stored in the online system
and can be reviewed and exported. Notifications can be
set up through the online system to alert the user when
thresholds have been met or exceeded.
The KWJ-WSN CO is pre-configured with the following
alert thresholds to provide essential data on low levels
of CO and to protect you from immediately dangerous
conditions:
• CO exceeding 50 ppm
• CO exceeding 125 ppm
• CO exceeding 400 ppm
• TWA (time weighted average) CO > 50 ppm
There are also several pre-configured thresholds that are
user changeable to allow further customization of your
alerts so you can receive notification about lower levels
of CO.
Power Options
Sensors are powered by a replaceable 3.0 V coin cell bat-
tery. Optional AA battery powered sensors are available.
The AA version of these sensors are larger in size (3" [L] x
2.1" [W] x 1.2" [H] ) and include two long-life AA batteries.
It is recommended that unless you are using the AA
battery solution, you set heartbeat to no faster than one
hour to preserve battery life.
