# How accurate is the Grow Sensor?

### E**nvironmental accuracy:**

* Temperature: ±0.5°C (1°F) | Range: -9°C to 58°C (15.8°F to 136°F)
* Humidity: ±1.3% | Range: 10% to 95% RH
* Leaf Temperature: ±0.5°C (1°F) | Range: -30°C to 100°C (-22°F to 212°F)

### C**O₂ monitoring:**

* Measurement Range: 400 ppm to 5000 ppm
* Accuracy: ±40 ppm + 5%

### L**ight & spectrum accuracy:**

* DLI (Daily Light Integral): ±3%
* Spectral Sensor:
* Wavelength Range: 380 to 910 nm
  * ePPFD (ePAR) Range: 400 to 750 nm
  * Blue Spectrum: 400 to 499 nm
  * Green Spectrum: 500 to 599 nm
  * Red Spectrum: 600 to 699 nm
  * Infrared Spectrum: 700 to 799 nm
  * Wavelength Accuracy: Typically ±2 nm per channel<br>

With this level of precision, the Grow Sensor ensures you have reliable data to optimise your grow space with confidence.
