Breathe Easy: Mutelcor’s Wireless CO₂ LoRa Sensor for Indoor Air Quality

During the COVID-19 pandemic, researchers discovered a notable link between CO₂ levels and the spread of the virus. They found that higher CO₂ concentrations were associated with faster transmission of the virus, as elevated CO₂ indicated poor ventilation and a higher likelihood of inhaling exhaled air containing the virus.

Further studies revealed that CO₂ levels exceeding 1000 ppm could lead to symptoms such as drowsiness, loss of concentration, and fatigue. As CO₂ levels rise to 2500 ppm, headaches may occur. Prolonged exposure to high CO₂ levels can also result in serious health conditions like Hypercapnia.

In many European countries, CO₂ sensors are mandatory in classrooms and other indoor spaces. This requirement stems from the need to manage indoor air quality without compromising heating efficiency. Steering the ventilation with devices like the Mutelcor Smart CO2 LoRa Sensor can ensure the air quality remains safe without the need for constant ventilation, helping maintain indoor warmth and reduce energy expenses.

LoRa (Long Range) Technology

LoRa is a wireless technology that operates on license free sub-gigahertz radio frequencies. It is designed to enable long-range transmissions with low power consumption, making it ideal for Internet of Things (IoT) applications.

What is the Mutelcor Smart CO₂ LoRa Sensor?

The Mutelcor Smart CO₂ LoRa Sensor leverages NDIR (Non-Dispersive Infrared) technology to measure carbon dioxide levels accurately. This advanced device also monitors temperature and humidity, delivering real-time data through a dedicated web dashboard.

The sensor measures CO₂ levels automatically every 2 seconds, and users can customize the interval for sending updates to the dashboard. This flexibility allows for tailored monitoring suited to specific needs.

Visual indicators on the device provide immediate feedback on CO₂ levels: a green light signals levels below 800 ppm, a yellow light indicates levels between 800 and 1000 ppm, and a red light warns of levels above 1000 ppm. If CO₂ levels exceed 1500 ppm, the red light begins to flash, signaling a critical threshold.

All collected data is recorded on the CO₂ sensor dashboard, accessible with various filter options for detailed review. In residential and office settings, the sensor’s thresholds for changing LED color can be adjusted to meet specific requirements.

For example, in environments like mushroom farming, where CO₂ levels may reach as high as 16,000 ppm, the sensor can be configured to display a green light within this range. A red light would then indicate levels falling below the threshold, while a yellow light might signal slightly elevated levels beyond the optimal range.

This level of customization ensures that the Mutelcor Smart CO₂ LoRa Sensor effectively meets diverse operational needs, maintaining safety and efficiency across various applications.
