Switchbot Meter Pro CO2 Thermometer & Hygrometer

6-in-1 weather station for comprehensive environmental monitoring, featuring a thermometer, hygrometer, air quality sensor, CO₂ sensor, date and time display, and smart alerts, with a clear 9cm screen

With the SwitchBot Meter PRO CO2, you’ll have a complete overview of CO₂ levels, temperature and humidity, time and date, and comfort level; you’ll receive notifications and can export your data.
If you also have a SwitchBot Hub, you can use additional features such as voice commands and weather forecasts.

6-in-1 multifunction display screen: The SwitchBot Meter Pro CO2 features a large screen that simultaneously displays CO₂ levels, temperature, humidity, time, date, comfort level and weather forecasts (SwitchBot Hub required). This makes it easy to monitor your environment and decide when to ventilate to create a healthier living space.

High-precision sensor: The SwitchBot CO₂ Meter is equipped with Swiss-grade industrial NDIR sensors and monitors air quality by measuring CO₂ levels every 1 second with an accuracy of ±50 ppm and a range of 400–9999 ppm. Its high sensitivity and stability ensure fast and precise feedback on air quality.

Multiple alarm methods: Customise the CO₂ and temperature and humidity thresholds for trigger alerts. If the thresholds are exceeded, you will be notified via audible alarms, visual on-screen warnings and app notifications (SwitchBot Hub required). This allows you to monitor air quality effectively at all times.

Part of the SwitchBot ecosystem: With Hub 2, exceeding CO₂ levels can automatically activate your battery-powered fan or evaporative humidifier for improved ventilation. Hub 2 also enables third-party voice control, simplifying air quality management.

Portable and durable: Our air quality detector measures 9.1 cm x 7.9 cm x 2.3 cm and weighs just 154 g. It has a built-in battery with a life of up to 12 months and a low-battery warning. It features holes for wall mounting and an adjustable bracket for versatile placement in any environment.
