Introduction

R711 is a long distance wireless temperature and humidity sensor based on LoRaWAN open protocol (Class A).

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.

Appearance

Main Features

• Compatible with LoRaWAN
• 2 section 1.5V AA Alkaline battery
• Report voltage status, temperature and humidity of indoor air
• Easy set up and installation

Set up Instruction

Power on and Turn on / off

1. Power on = Insert batteries: open the battery cover; insert two sections of 1.5V AA batteries and close the battery cover.
2. If the device had never joined in any network or at factory setting mode, after powering on, the device is at off mode by default setting. Press function key to turn on the device. The green indicator will flash green once to show that R711 is turned on.
3. Press and hold function key for 5 seconds till the green indicator flashes quickly and release. The green indicator will flash 20 times and enter off mode.
4. Remove batteries (power off) when R711 is on. Wait till 10 seconds after the capacitance discharging. Insert batteries again, R711 will be setted to be previous mode by default. There is not need to press function key again to turn on the device. The red and green indicators will both flash and then light off.

Note:

1. The interval between shutting down twice or power off/on is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other energy storage components.
2. Do not press function key and insert batteries in the same time, otherwise, it will enter engineer testing mode.

Join Into Lora Network

To join R711 into LoRa network to communicate with LoRa gateway

The network operation is as following:

1. If R711 had never joined any network, turn on the device; it will search an available LoRa network to join. The green indicator will stay on for 5 seconds to show that it joins into the network, otherwise, the green indicator does not work.
2. If R711 had been joined into a LoRa network, remove and insert the batteries to re-join the network. Repeat step (1).

Function Key

1. Press and hold function key for 5 seconds to reset to factory setting. After restoring to factory setting successfully, the green indicator will flashes quickly 20 times.
2. Press function key to turn on the device; the green indicator flash once and it will send a data report.

Data Report

When the device is turned on, it will immediately send a version package and a data report of temperature/humidity/voltage. The transmission frequency of data report is once every hour.

Temperature default report value: mintime = maxtime = 3600s, reportchange = 0x0064 (1 ℃), Humidity default report value: mintime = maxtime = 3600s, reportchange = 0x0064 (1%), Battery voltage default report value: mintime = 3600s maxtime = 3600s, reportchange = 0x01 (0.1V).

Note: MinInterval is the sampling period for the Sensor. Sampling period

= MinInterval.
Data report configuration and sending period are as following:

Min Interval (Unit:second)

| Max Interval (Unit:second)| Reportable Change| Current Change≥ Reportable Change|

Current Change ＜ Reportable Chang

---|---|---|---|---

Any number between 1~65535

| Any number between 1~65535| Can not be 0.| Report per Min Interval|

Report per Max Interval

Restore to Factory Setting

R711 saves data including network key information, configuration information, etc. To restore to factory setting, users need to execute below operations.

1. Press and hold function key for 5 seconds till the green indicator flashes and then release; LED flashes quickly 20 times.
2. R711 will enter off mode after restoring to factory setting. Press function key to turn on R711 and to join a new LoRa network.

Sleeping Mode

R711 is designed to enter sleeping mode for power-saving in some situations:

(A) While the device is in the network → the sleeping period is 3 minutes. (During this period,
if the reportchange is larger than setting value, it will wake up and send a data report). (B) When it is not in the network to join → R711 will enter sleeping mode and wake up every 15 seconds to search a network to join in the first two minutes. After two minutes, it will wake up every 15 minutes to request to join the network.

If it’s at (B) status, to prevent this unwanted power consumption, we recommend that users remove the batteries to power off the device.

Low Voltage Alarming

The operating voltage threshold is 2.4V. If the voltage is lower than 2.4V, R711 will send a low-power report to the Lora network.

Important Maintenance Instruction

Your device is a product of 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 moisture 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 can damage its detachable parts and electronic components.
• Do not store in excessive heat. 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. Rough handling of equipment can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not apply with paint. Smudges can block debris in detachable parts and affect normal operation.
• Do not throw the battery into a fire to prevent the battery from exploding. Damaged batteries may also explode.

All of the above suggestions apply equally to your device, battery and accessories. If any device is not working properly.
Please take it to the nearest authorized service facility for repair.
