The Aranet4 sensor is a sophisticated, battery-powered CO₂ meter designed for environmental monitoring in various indoor settings such as schools, offices, and homes. Beyond CO₂, it also measures temperature, relative humidity, and atmospheric pressure, providing a comprehensive overview of indoor air quality.
The primary function of the Aranet4 is to monitor CO₂ levels, offering real-time data displayed on an energy-efficient e-ink screen. This display ensures long battery life, making it a low-maintenance device. The sensor is equipped to provide both visual and audible notifications if CO₂ levels exceed a predefined high concentration threshold, typically set at 1400 ppm. This threshold is associated with symptoms like drowsiness and poor air quality, alerting users to potential issues that may require ventilation or other interventions.
The device operates with two main communication protocols: Bluetooth and Aranet radio. Bluetooth connectivity allows the Aranet4 to pair with smart devices (iPhones and Android phones) via the Aranet4 app. This app provides access to current and historical measurement data, enabling users to track trends and make informed decisions about their indoor environment. It also allows for remote configuration of the Aranet4 device, including adjusting settings like CO₂ calibration mode, temperature units, and buzzer activation.
For larger-scale deployments, the Aranet4 can connect to an Aranet PRO base station using its Aranet radio connectivity. An Aranet PRO base station can manage up to 100 Aranet sensors, collecting, storing, and maintaining measurement data for extended periods, up to 10 years, in its local memory. This feature is particularly useful for businesses or institutions that require continuous monitoring across multiple locations or rooms.
The CO₂ measurement calibration can be set to either automatic or manual. In automatic mode, the device self-calibrates by requiring exposure to fresh air (around 400 ppm CO₂) daily. Manual calibration provides users with the flexibility to initiate calibration when needed, typically by exposing the device to fresh air in a stable environment.
The Aranet4 offers several user-friendly features designed to enhance its usability and effectiveness:
The Aranet4 is designed for ease of maintenance, focusing on user convenience and long-term reliability:
In summary, the Aranet4 is a versatile and user-friendly environmental monitoring device that combines accurate CO₂, temperature, humidity, and atmospheric pressure measurements with smart connectivity and intuitive controls, making it an ideal solution for maintaining healthy indoor environments.
