Kaiterra Sensedge Mini Air Quality Monitor Made in China [email protected] Origins Technology Limited. 603 6/F, Laws Commercial Plaza, 788 Cheung Sha Wan Road, Hong Kong ENGLISH Kaiterra Sensedge Mini Air Quality Monitor User Manual What’s Included ● Sensedge Mini ● Sensedge Mini sensor modules x 2 ● Surface / Drywall mount ● Electrical box mount ● Drywall screws and anchors (3 pairs) ● Electrical box screws (US) x 2 ● Electrical box screws (China and EU) x 2 ● Fastening screws x 2 ● USB cable ● Charger ● Certificate of calibration and testing ● User manual ● Certificate of conformity Important Safeguards Please read the safety warnings before use and take the necessary precautions to reduce the risk of fire, electric shock, or injury. The Kaiterra limited warranty applies only if the unit is used according to these instructions. WARNING ● To reduce safety risks, always use service personnelfrom the manufacturer or service provider, or other qualified personnel for installation and maintenance. ● Make sure the power is OFF during installation or maintenance. ● DO NOT tamper with or use nonofficial spare parts for repair or maintenance. ● DO NOT use the device in environments with high humidity or possible direct exposure to water. ● DO NOT use the device in an outdoor environment. ● DO NOT use the device near heat sources such asradiators, furnaces, ovens, or stoves. Getting Started The Sensedge Mini is a commercial-grade air quality monitor. This user manual will provide a basic guide to its first use. Further information can be found on the Kaiterra Support Portal athttp://support.kaiterra.com/sensedge-mini Operational Temperature：0 - 40°C Externals and Air Flow Air is drawn into the Sensedge Mini from the lower side, as well as the air intake on the upper side. It is vital that neither side of the device is covered. Any changes in airflow may affect the readings and accuracy. Power and Connectivity The Sensedge Mini provides multiple power and connectivity options: Power: ● USB-C: Only use the cable and charger/adapter suppliedwith the device ● DC direct wiring: Used for power supply of 12V,1000mA ● PoE (Power over Ethernet): Available for model SE000200P Connectivity: ● 2.4GHz Wi-Fi (802.11 b/g/n) ● Ethernet: Used for data transfer via Ethernet ● RS-485: Used for Modbus communication ● Bluetooth Sensor Modules The Sensedge Mini utilizes a modular design to allow for easy control and replacement of sensors. A CO2 sensor and a temperature and relative humidity sensor areis built into the core of the device, and a variety of other sensors may be inserted using the two sensor bays on the lower side of the device. To insert a sensor module, simply align it with the bay and press it in, ensuring the Kaiterra logo on the plastic tab is facing outwards. When inserted correctly, the module will click into place, and an LED light above the bay will briefly flash red if the device is powered on. To remove a sensor module, gently pull the tab outward and remove the module from the bay. Make sure to pull at a 90 degree angle. Sensors may be inserted in either sensor bay, and in any order. They may be swapped both when the Sensedge Mini is powered on and operational, and when the device is turned off. By default, the Sensedge Mini is shipped with the KM-200 and KM-203 sensor modules, which together measure PM2.5, and TVOC., temperature, and relative humidity. Sensor Module Status Light Indications: Steady OFFSensor working normal Flash red onceSensor module powered on Steady ONSensor module needs to be changed FlashSensor module failure Flash slowlySensor module in sleep mode Control and Status Move the ON/OFF switch right to turn on the device. The STATUS light will go on briefly to indicate the device has been powered on. To reset the device, use a paperclip and hold down the RESET pinhole. The STATUS light will flash red rapidly, indicating that the reset is successful.
