Netvox Wireless CO2/Temperature/Humidity Sensor

1. Introduction

RA0715_R72615_RA0715Y is a Class A device based on the LoRaWANTM protocol of Netvox and is compatible with the LoRaWAN protocol. RA0715_R72615_RA0715Y can be connected with the sensor of the temperature and humidity, and CO2. The values collected by the sensor are reported to the corresponding gateway.

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 equipment, 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.

5. Data Report

After power on, the device will immediately send a version packet report and two data reports including CO2, temperature, humidity and voltage. The device sends data according to the default configuration before any other configuring.

ReportMaxTime:

RA0715 and RA0715Y is 900s, R72615 is 1800s (subject to original setting)

• MaxTime cannot be set less than 15 min
• The value of the ReportMaxTime should be greater than ReportType count *ReportMinTime+10

ReportMinTime:

• 30s (US915, AU915, KR920, AS923, IN865)
• 120s (EU868)

ReportType count: 2

Note:

1. The cycle of the device sending the data report is according to the default.
2. The interval between two reports must be the MaxTime.
3. ReportChange is not supported by RA0715_R72615_RA0715Y (Invalid configuration). The data report is sent according to ReportMaxTime as a cycle (the first data report is the start to the end of a cycle).
4. Data pocket: CO2, temperature, and humidity.
5. The CO2 sensor operates stably. It takes about 180 seconds after power-on to send the data report.
6. The device also supports the TxPeriod cycle configuration instructions of Cayenne. Therefore, the device can perform the report according to the TxPeriod cycle. The particular report cycle is ReportMaxTime or TxPeriod depending on which report cycle was configured last time.
7. It would take 180 seconds for the sensor to sample and process the collected value after pressing the button, please be patient.

The device reported data parsing please refer to Netvox LoraWAN Application Command document and Netvox Lora Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index

6. Installation

1. RA0715 does not have the waterproof function. After the device completes joining the network, please place it indoor.
2. R72615 has a waterproof function. After the device completes joining the network, please place it outdoors.
   • (1) In the installed position, loosen the U-shaped screw, the mating washer and the nut at the bottom of R72617, and then make the U-shaped screw pass through the appropriate size cylinder and fix it on the fixing strut flap of R72615. Install the washer and the nut in order and lock the nut till R72615 body is stable and does not shake.
   • (2) At the upper side of the fixed position of R72615, loosen the two U-shaped screws, the mating washer and nut on the side of the solar panel. Make the U-shaped screw pass through the appropriate size cylinder and fix them on the main bracket of the solar panel and install the washer and the nut in sequence. Lock nut till the solar panel is stable and does not shake.
   • (3) After adjusting the angle of the solar panel completely, lock the nut.

7. Important Maintenance Instruction

The device is a product with superior design and craftsmanship and should be used with care. The following suggestions will help you use the warranty service effectively.

• Keep the equipment 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 equipment 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.
