• Wireless & Retrofit
• Measures Ambient CO2 in ppm
• Can Trigger Safety Alert
• Cloud Connected with In-App Visualisation and Analytics
• Easy Setup
• Works with Android & iOS User Applications

• This sensor has good sensitivity and selectivity to CO2 with low humidity and temperature dependency.
• The CO2 sensor data is communicated over Zigbee to the NUOS Zigbee Gateway and the appropriate actions based on the Safety Mode (triggering safety alert SMS & In-app Notification) are triggered by the Gateway if the mode is enabled.
• Has in-built Zigbee and acts also as a repeater for Zigbee Mesh Network.
• Can be accessed in dual mode – local only through the same WiFi network as well as through cloud from anywhere in the world for seamless connectivity using Android and iOS Application.
• Supports ease Safety Mode Enable/Disable from mobile application.
• Support IFTTT for taking action based on certain triggers
• Supports change of settings through cloud from anywhere in the world.

• Please check NUOS Zigbee Gateway configuration for setting up and configuring the gateway.
• Push the NUOS Sensor inside the switch plate till it snap fits.
• Connect the Red Wire from behind the sensor to the Line/Live wire of the electrical circuit.
• Connect the Black Wire from behind the sensor to the Neutral wire of the electrical circuit.
• Make sure the wiring connections are tightly secured by insulation/electrical tape to above lose connections and arcing behind switchboard.
• Close the switch board once the wiring is completed.
• New switches and sensors automatically associate with the gateway on power-up and can be added in the desired room using the user application.
• Please refer to the installation manual for detailed process with images.
