CO2 and climate monitor for indoor spaces, designed to give fast, precise air-quality readings and clear alerts. Homeowners, schools and small offices gain confidence about when to ventilate and when to automate fans or humidifiers. Is the SwitchBot CO2 Detector the right choice for a connected home or a simple standalone meter?
⚡ At a Glance
- • Sensor Accuracy: NDIR Swiss industrial-grade sensors, ±50 ppm accuracy, 400–9999 ppm range
- • Best for: Homeowners, office managers and schools needing timely CO2 and climate readings
- • Not ideal for: Users who require Wi‑Fi monitoring without adding a SwitchBot Hub
High-sensitivity NDIR sensing samples CO2 every 1 second for rapid feedback. Large screen shows CO2, temperature, humidity, time and comfort level, with extended features when paired with a SwitchBot Hub 2.
Rapid, reliable CO2 alerts – Thanks to NDIR Swiss industrial-grade sensor
NDIR sensors measure carbon dioxide at 1-second intervals with ±50 ppm accuracy across a 400–9999 ppm range. High sensitivity and stability deliver consistent readings suitable for occupied spaces.
Fast sampling helps spot rising CO2 before occupants feel drowsy, enabling timely ventilation. Sound, visual and app alerts (when paired with a SwitchBot Hub) warn when custom thresholds are exceeded.
Clear environmental snapshot – With a six-in-one multi-functional display
The large display simultaneously presents CO2 levels, temperature, humidity, time, date and comfort level, and can show weather forecasts when used with SwitchBot Hub 2.
A quick glance reveals whether a room needs airing or humidifying, removing guesswork from daily checks. Wall-mount holes and an adjustable bracket make placement flexible for living rooms, classrooms and meeting rooms.
Automated ventilation control – With SwitchBot ecosystem compatibility
Pairing with a SwitchBot Hub enables automated actions, such as triggering a Battery Circuit Fan or an Evaporative Humidifier when CO2 thresholds are exceeded, and allows third-party voice control.
Automation reduces manual intervention during busy periods, keeping air fresher without constant attention. Integration suits smart homes or small offices that already use SwitchBot accessories.
✨ The 4 Key Reasons for SwitchBot CO2 Detector
- 1-second sampling rate – Detects CO2 changes quickly for timely ventilation decisions
- Up to 12 months battery life – Minimal maintenance with long between-charge intervals
- Hub-triggered automation – Automatically activates fans or humidifiers when limits are exceeded
- Compact, mountable design – Fits wall or shelf placement, ideal for classrooms and meeting rooms
