In the latest firmware, we have added a more human‑friendly text prompt that describes the current formaldehyde status with simple words.
Compared with cold numbers, this makes it much easier to understand at a glance.
According to common formaldehyde standards, here are some reference values:
- 0.05 mg/m³ (≈ 41 ppb) – Excellent
- 0.08 mg/m³ (≈ 65 ppb) – Good
- 0.10 mg/m³ (≈ 81 ppb) – Typical upper limit
- 0.50 mg/m³ (≈ 407 ppb) – Clearly excessive
During testing, the sensor has proven to be very sensitive and stable, with minimal interference — truly impressive Swiss technology.
We are now in the final testing stage and also working on the enclosure design. We believe we will be able to share more with you soon.
Unfortunately, due to the high cost of the module, the final price of this sensor is expected to be around 45 USD, making it the most expensive sensor we have ever made.
