Short-distance wireless (optional)	ZigBee or 2.4G IEEE 802.15.4 protocol available, as well as another appointed protocol. Automatic buildup network, 16 channels, automatically select a reliable channel based on the environment. The reliable transmission is up to 1000 meters in the visible range.

The standard monitor has below two models

1.Carbon dioxide(CO₂)+CO₂average +Temperature+ Humidity (Model:DPM-1003)

2.Carbon dioxide(CO₂)+CO₂average +VOC +Temperature+ Humidity (Model:DPM-1004)

Two unique extended functions (Optional)

1.RF short-distance wireless transmission & reception

2.USB data logging

The product can be worked together with our wireless controller to control a ventilator, air cleaning device, or humidity device, based on the real-time measurements and the presetting values of the monitor.
