Wireless Aggregator

Wireless Aggregator is a general term for a range of Sensor /DTU devices for outdoor scenarios, and its sub-models integrate a variety of standard sensors and can also be used to connect third-party sensors, solenoid valves, and upload there data to the LoRaWAN network. It reserves enough pins for current input and output, reading electrical pulse signals, connecting solar cells and other functions.


The Wireless Aggregator Series has three branches:

  • Integrated-sensor, customization support.
  • All sensors are rigorously tested, high sensitivity, high accuracy.
  • Equipped with waterproof and breathable membrane.

Sensor Hub Can Embedding the Following Sensors:

HRI-3632 Bus Transformer

  • Used to actuate third-party sensors.
  • Flange seat interface.
  • Provide waterproof junction box, support RS485, 4~20mA signal.
  • A variety of sensors have been provided to choose from, support more sensor customization.

We provide a variety of RS-485 sensors:

Solenoid Valve Controller

  • Used to actuate solenoid valves.
  • Flange seat interface.
  • Provide waterproof junction box.
  • Reading electrical pulse signals.

Key Features

Rapid Deployment

Devices can be registered to the Heltec Snap Emu platform with just one click through APP scanning or Bluetooth, data display, data subscription, and management can be achieved on the platform side.

Multi Platform Support

The device integration standard LoRaWAN protocol, in addition to the Heltec SnapEmu IoT Platform, can also support commonly used IoT platforms such as ChirpStack, TTN/TTS, AWS, MQTT subscription, etc.

High Reliability

The equipment has a clever structural design, which not only ensures a beautiful appearance and convenient installation, but also has good protective characteristics, Protection class IP66.

Modular Design

The whole series adopts modular design, which can achieve different functions by replacing sensor modules, making it more flexible to cope with different usage scenarios.


All models can be connected to solar rechargeable battery or directly connected to solar charging panel. Ensure long-term sustainable work in outdoor scenarios.

Low-power Design

Built-in 4x1900mAh rechargeable battery and magnetic charging interface. The sleep current is as low as 9μA and can be maintained for several years of operating time on a single charge.


Wireless Aggregator has excellent low power consumption characteristics and LoRa provides Long-distance transmission capability. It comes with 4 built-in 2000 mAh rechargeable battery and magnetic charging interface. The high-strength plastic provide an IP66 protection level, allowing it to perform stably and excellently in complex outdoor environments.
