Getting Started


HRU-3622 is a sub-model of the Sensor Hub for outdoor series that specifically drives third-party sensors. Its interface is a flange seat, with 2 RS485 interfaces and 4 GPIO interfacesIt can be used to drive a variety of third-party sensors. Sensor Hub for Industry has excellent low power consumption and long transmission distance characteristics, comes with a built-in 1100mAh rechargeable battery. The stainless-steel shell and high-strength plastic provide an IP66 protection level, allowing it to perform stably and excellently in complex industrial environments.

Power supply

HRI-3622 integrates a 1100aMh rechargeable lithium battery, charging voltage is 5V and its charging interface is magnetic-2P, a single filling time is about 3~4 hours.

LED light status description

The HRI-362x series has a wealth of indicator effects, which can help you more easily use the device, or determine the status of the device.

Connect third-party sensors

There are two recommended ways to connect sensors:

Connect the sensor directly to the HRI-3622.

  • We provide 12mm 8Pin flange conversion head, first through the flange seat diagram below, you can connect the pin of the sensor to the conversion head.

  • Connect the conversion head to the flange seat of the sensor hub and gently screw it on.

Connect via Junction box

  • Connect the sensor junction box.

  • Connect the Junction box with the conversion head.

  • Connect the conversion head to the flange seat of the sensor hub and gently screw it on.


Enter Configuration mode

  • Long press the button on the top of the device, and the device will first display white light and then orange light. At this time, release your finger.


If long press does not respond, try to connect the charging cable to wake up the battery management system. If the blue light/green light blinks sequentially after long press, it means that the device is in working state. After 5 seconds, when the light is all out and no longer blinks, release your finger and long press again to enter the configuration page.

  • Find the WiFi named Sensor_Hub_xxxx with your PC or mobile phone, connect it.

  • In the browser, type, enter the configuration page.

OTA UPDATE: Sensor Hub for Industry series supports OTA upgrade.


Power off

After the configuration is completed, long press the button for five seconds, and when the light goes off, the device is shut down.

Power on

Press the button for 3 seconds. When the button shows white light, release the button. At this time, the device enters the working state, where the sending is green light and the receiving is purple light.

Common problems and solutions

  • Unable to confirm device working status. Press the device button once, and if it shows blue light, it will wake up, and the device will upload a message immediately.

  • Device not working: After each configuration, you must button off in, then button on.
