Accurate CO₂ monitoring is vital for maximising plant growth, especially in controlled indoor environments where CO₂ levels directly impact photosynthesis and yield.
Two standout devices provide high-precision CO₂ readings trusted by professional growers:
Technology: High-accuracy NDIR (nondispersive infrared) sensor module
Accuracy: ±30 ppm ±3% of reading
Use case: Integrated into advanced monitoring systems for ultra-precise CO₂ measurement
Pros: Laboratory-grade accuracy; reliable long-term performance
Cons: Module-only – requires integration into a larger system; not plug-and-play
Approximate price: $150 USD
Technology: Built-in NDIR CO₂ sensor with real-time monitoring
Accuracy: ±50 ppm ±3% of reading (factory-calibrated for accuracy)
Monitors: CO₂ levels, temperature, humidity, light intensity (PPF/PPFD + ePAR), and leaf surface temperature
Accuracy: High-precision readings suitable for professional indoor cultivation
Features: Real-time cloud access, automated data logging, mobile alerts
Pros: All-in-one device; no setup required; mobile access; robust and durable
Cons: Does not monitor soil moisture, pH, or EC directly but is compatible with several substrate probes.
Price: £599 GBP (View product)
Integrating accurate CO₂ sensors into your cultivation setup ensures optimal CO₂ levels are maintained—reducing plant stress and increasing yields.
Grow Sensor PRO offers professional-grade CO₂ monitoring alongside full environmental tracking, making it a cost-effective and complete solution for serious growers.
