Dual Channel Infrared Carbon Dioxide Sensor Indoor Air Monitoring Purifier Co2 Detection
4 reviews

Features:

Newly-stocked dual-channel infrared carbon dioxide sensor module,
Dual-channel detection,
It seems that the accuracy is higher than single channel,
And stable,
The mirror surface of the stock module housing feels a bit scratched,
The module pins have not been tinned and soldered,
The inside of the module is very new,
Research price processing,
The specific information of the module needs to be checked online by yourself.
This shop does not provide technical support,
Module clearance special offer processing.
