General Description
KWJ’s WSN-CO detects 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 alarms.
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 monitoring and notification system to configure sensors, view data and set alerts via SMS text and email
Principle of Operation
Electrochemical CO, Ambient Diffusion
When the battery is installed, the sensor must be allowed a 15 minute warm-up period. Once complete, the sensor can accurately measure the ambient level of CO and send data to the KWJ-WSN Online Sensor Monitoring and Notification 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 exceeding 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 battery. 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.
