CO2 Monitor Switchbot Meter Pro — CO2, Temperature & Humidity Measurement, LCD, Battery (AA), ABS Housing, 5 V, Temp Range -20–80°C

SwitchBot Meter Pro CO2 thermometer and hygrometer.

It's not just a temperature-measuring device - the SwitchBot Meter Pro CO2 is a compact air quality monitoring station that continuously displays CO₂ levels, humidity, temperature, current time and overall ambient comfort. One glance at the display is enough to know when to ventilate a room or how to ensure a better climate in the office, bedroom or child's room. Accuracy, fast readings and smart features make this device really take care of your daily comfort.

5 values on one screen

You can see everything important on the LCD display: carbon dioxide (CO₂) level, temperature, humidity, time of day and overall comfort indicator. You don't have to look in the app or switch screens - the data is always at hand. This is a practical solution especially where quick access to information matters, such as in conference rooms, home offices and children's rooms.

Accuracy you can rely on

The SwitchBot Meter Pro CO2 uses NDIR technology and industrial-grade Swiss precision sensors to provide highly accurate measurements. When powered by USB-C, readings are updated every second, allowing you to react almost instantly to changes in air quality. The CO₂ measurement range is as high as 400 to 9999 ppm, with an accuracy of ±(50 ppm + 5%).

Three types of alarms - no change will escape you.

When the CO₂ level, temperature or humidity exceeds the set thresholds, the device can alert you with a sound, a message on the screen or a notification in the app. This is a great feature, for example, for parents, allergy sufferers or people who work remotely and want to have full control over the air quality in the room. The SwitchBot Hub is required for the app notifications to work.

Flexible mounting and power supply

You can place the device on your desk, attach it to the wall, or position it at any angle with the adjustable stand (0-90°). You can choose to power it via USB-C or battery mode, which lasts up to 12 months. This way the device fits into any interior and doesn't need a constant power source.

Data that works for you

With the SwitchBot app, you can export air quality data - locally for up to 38 days, and in the cloud for up to 2 years. If you use other SwitchBot devices and have a Hub, you can create automations - for example, when CO₂ levels exceed a threshold, the app will open smart curtains or run a fan. The top buttons on the case allow you to quickly mute an alarm, refresh data or change units - without reaching for your phone.

How to use

Place the Switchbot Meter Pro in the zone you want to monitor at typical breathing height and away from direct airflow sources such as vents or open windows for representative readings. Power the device with AA batteries and allow it to stabilise for several minutes before taking measurements. Read CO2, temperature and humidity values directly on the LCD; use the device controls to refresh readings or switch display units if available. For periodic checks, move the meter between rooms and note variations in concentration to decide on ventilation actions.

Recommendations

For reliable comparison of indoor air quality over time, record measurements under similar placement and occupancy conditions. If CO2 readings consistently exceed recommended indoor levels, increase ventilation or reduce occupancy until concentrations fall to acceptable ranges.
