1. Introduction
R718UBD all-in-one series is a ClassA type of netvox based on LoRaWAN open protocol, which can support a variety of combined
detection devices composed of temperature and humidity, CO2, vibration, atmospheric pressure, illumination, TVOC and dust, and is
compatible with LoRaWAN protocol.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other
communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely
used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation device,
wireless security systems, industrial monitoring. Main features include small size, low power consumption, transmission distance,
anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and
gateways from different manufacturers.

R718UBD236, R718UBD237
Data detection:
When the device is in a network state, the light flashes once after pressing the key, and then reads the data. When the time to
return the corresponding data or configure is up, it will also detect and return the corresponding data information.
(Note: The interval between multiple data packets is mintime)
Note:
1. Before any configuration, the device sends data according to the default configuration.
2. Do not send any configuration before turn on the device.
3. CO2 data will be unstable due to transportation relations, long storage time and other factors.
If the CO2 value which customers test is inconsistent ,or there is large discrepancy of the primary standard,
it can be recalibrated. For specific calibration methods,please refer to command 0x03 CalibrateType.
Refer to Netvox LoRaWan Application Command documents and for data analysis reported by the device

6. Installation
The waterproof breathable film inside the product is waterproof but not waterproof against steam. Therefore, in order to prevent water
vapor from condensing inside the body, it should not be used in high humidity and steam environments.
6-1 Precautions for use of dust sensor
The sensor is made of water-resistant, dust-proof, and impact resistant materials. However, precision instruments need to be
carefully used and maintained to avoid impact and use in harsh environments such as corrosive liquids or gases.
The air inlet of the sensor shall not be blocked or polluted.
The electrolyte leakage will cause damage. Do not disassemble the sensor at will.
Do not use it when the shell is damaged or deformed.
The sensor shall avoid contact with organic solvents (including silicone rubber and other adhesives), coatings, agents, and fuel oils.
It is not recommended to use non-standard methods to test the sensor, and vertical air intake must be avoided. For example, put
the sensor directly on the concentrated ammonia, spray cigarettes towards the sensor, approach the sensor after the lighter is lit,
exhale towards the sensor, and close the sensor to alcohol. Because the regional concentration can be as high as tens of thousands
of ppm when liquid ammonia or alcohol volatilizes, and the carbon dioxide concentration in human breath can be as high as 40000
ppm, which will damage the sensor.
After being used for a long time in a high-concentration gas environment (it is prohibited to store and use it in a high-concentration
acid gas for a long time), it is slow to recover to the initial state.
When the sensor is stored, the working electrode and the reference electrode should be in a short circuit state.
The sensor is not allowed to be hot-plugged. The sensor must be plugged in after the power is turned off, otherwise, the sensor
may be damaged or abnormal phenomena may occur.
Please pay attention to whether there are requirements for limiting the use of wireless communication devices in this situation. If
there are such restrictions, please do not use this device. For example, during aircraft flight and landing, gas stations, gas stations
or other places with flammable and explosive materials.
6-2. Precautions for use of TVOC sensor
The installation place shall be far away from chemical corrosion environment.
The sensor and wire shall be far away from high-voltage electricity, heat source, etc.
The sensor belongs to precision instrument and should be stored in a dry, ventilated and normal temperature indoor environment.
The sensor is a precision device. Please do not disassemble it when using it to avoid product damage.

6-3 Precautions for outdoor installation
According to Enclosure Protection Class
This standard is equivalent to IEC 60529:2001 Degrees of Protection Provided by Enclosures
The test method of IP65 waterproof grade is:
spray the device in all directions under 12.5L/min water flow for 3min, and the internal electronic function is normal.
The test method of IP67 waterproof grade is:
the device is immersed in 1m deep water for 30min, and the internal electronic function is normal.
IP65, dust-proof and to prevent damage caused by water from nozzles in all directions from invading electrical appliances. It can be
used in general indoor environment and sheltered outdoor environment.
It is not suitable for use in environments with high water pressure,high temperatureand high humidity, such as long time direct sunlight
outdoors and possible direct exposure to rainstorm. If it is really necessary to install in harsh environments, it is recommended to add
sunscreen and rainproof shields when installing.
Case I (face down with LED and buttons) Case II (installed under the rain shield)

7. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the device dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case the
device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
• Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or
melt some plastic parts.
• Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which
will destroy the board.
• Do not throw, knock or shake the device. Treating device roughly can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
• Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries and accessories.
If any device is not operating properly, please take it to the nearest authorized service facility for repairing.
