The wireless duct-type CO2 sensor is the remote wireless sensor to measure the carbon dioxide density in the duct that the CO2 density measured through the CO2 sensor of the internal NDIR method to carry out the wireless communication between the sensor and upper controller to save the work cost by having easy installation without the pipes and wires.

The wireless duct-type temperature & humidity sensor senses the temperature and humidity in the duct through the static capacity change humidity sensor that requires no platinum measurement resistance (Pt 100 Class A) or separate calibration to transmit the measurement data to the upper control device wirelessly.

The wireless outdoor-type temperature & humidity sensor senses the temperature and humidity outside through the static capacity change humidity sensor that requires no platinum measurement resistance (Pt 100 Class A) or separate calibration to transmit the measurement data to the upper control device wirelessly.

The wireless indoor-type temperature & humidity sensor senses the temperature and humidity outside through the low power CMOSens temperature sensor and the static capacity change humidity sensor to have the high capacity lithium battery inside to save the work costs by easy installation with the remote wireless sensor without any pipes and wires.

The wireless actuator has the proportional control auto damper operator with the proportional control auto valve actuator, and the proportional control signal is received wirelessly to proportionally control the fluid to maintain the interior odor and humidity to use in cooling, heating and hot water temperature control.

The wireless Zigbee coordinator forms the Zigbee network and connect to another network to have each network to have a Zigbee coordinator. Zigbee coordinator may save information on the network and the Trust Center may carry out the role as the storage for security key.

The wireless sub-giga coordinator forms the sub-giga network of 900MHZ bandwidth and it connects to another network and others, and each network has one sub-giga coordinator. The sub-giga coordinator may save the information on the network and it carries out the net management of sensor or controller existing in the network.

NPT-R00 detects the flux or steam temperature and NDT – R00 is the remote wireless sensor for measuring the air temperature flowing within the duct that it may save work costs with easy installation without requiring separate signal line.

The NHT-W00B energy harvesting indoor-type wireless temperature & humidity sensor is the remote wireless sensor for measuring the relative humidity and temperature inside to save work costs with easy installation without pipe and wires. In addition, on the basis of the super low power design, it realizes the energy circulation of solar energy and interior light and battery to be able to use semi-perpetually without replacing the battery.

The wireless Zigbee router is the wireless communication relay used to expand the communication distance on the network that is structured in Zigbee and it enables the long distance communication to resolve the communication distance production of the wireless devices. It adopts the Zigbee mesh network protocol and produced to meet the 2.4GHz IEEE802.15.4 dimension to improve the data traffic and carry out broad range of communication.
