# Software for CO2 Monitor
## Compatible Devices
This software supports compact USB-powered CO2 meters that identify as:
```
idVendor 0x04d9 Holtek Semiconductor, Inc.
idProduct 0xa052 USB-zyTemp
```
A of 2023, there are two revisions of these product on the
market, that can be distinguished by its serial and release
numbers:
```
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
old new
――――――――――――――――――――――――――――――――――
serial_number 1.40 2.00
release_number 0x0100 0x0200
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
```
(where serial_number == iSerial and release_number == bcdDevice)
The co2mon software tries to auto-detect them, but its also possible to
override the detection (cf. the `-N` and `-n` options).
Note that these devices are rebranded by vendors such as TFA and
thus are available online under different product names (e.g.
sold by Amazon, as of 2023). Even if one user reported success
with a certain product, the vendor might have silently switched
to a completely different and unsupported hardware without
changing the product name, at any time.
List of user reported devices that worked in the past:
- TFA AIRCO2NTROL MINI CO2 Monitor (EAN 4009816027351), via
Amazon.de, 2023
