LoRaWAN Wireless environmental sensor
• LoRa long range wireless
Battery or externally powered
Built in sensors for:
Temperature (°C)
Carbon Dioxide (CO
Barometric Pressure (Pa)
Volatile Organic Compounds (VOC's)
Temperature
Humidity
enLink Zone Plus accurately measures multiple environmental
parameters including room temperature, humidity, CO
level, pressure and sound level*.
Volatile Organic Compounds (VOC's) from paints (such as
formaldehyde),
lacquers,
furnishings, office equipment, glues, adhesives and alcohol can be
detected and reported down to the ppm range.
Readings are transmitted to the cloud using long range LoRa wireless,
where the data can be displayed and analysed.
The unit can be either externally or battery powered for maximum
flexibility.
A built in USB port allows all parameters including air quality data,
wireless signal strength and wireless network configuration to be
viewed and set using simple menus via any USB enabled host such
as a PC or Mac.

  • Page 2 Note: In LoRaWAN 1.1, AppEUI was renamed to JoinEUI. For many applications Synetica can supply enLink units with the above parameters pre-configured, so providing the LoRa gateway has the matching keys the join process will happen automatically once the enLink unit is in wireless range and switched on.
  • Page 3 Zone Plus Label The unique DevEUI is printed on all enLink devices and is also present in the QR code. The DevEUI can be used to identify the device once joined to the network. SYNETICA enLink Zone Plus User Guide Rev 1.6...
  • Page 4: Powering The Unit

    When in the EXT position, the batteries are automatically disconnected. To power the device ON, remove the rear cover of the enLink Zone Plus by inserting a small screwdriver blade into the slots on the bottom of the unit as shown below.
  • Page 5 Once powered ON, the enLink device will send a Join request message to the gateway. The Status LED will blink RED as shown below whilst the Join process is taking place. Depending on factors such as signal strength, RF interference etc the Join process may take several seconds to complete. SYNETICA enLink Zone Plus User Guide Rev 1.6...
  • Page 6 Connect a micro USB cable to the enLink unit. There are two USB connectors on the enLink Zone Plus, so be sure to connect to the correct USB port as shown in the image below. SYNETICA enLink Zone Plus User Guide Rev 1.6...
  • Page 7 In your terminal program press the Enter key. An enLink summary screen will appear as shown below. The default password is the last four digits of the displayed DevEUI, in the screen below this is 9377. enLink logon screen SYNETICA enLink Zone Plus User Guide Rev 1.6...
  • Page 8 Enter R to reboot followed by OK. The device will restart with the entered AppEUI and AppKey and attempt to join the LoRa network. Reboot Required notification Check the Conduit LoRaWAN -> Devices menu detailed previously to verify that the enLink device has joined successfully. SYNETICA enLink Zone Plus User Guide Rev 1.6...

  • Page 13 PIR Sensor Operation The PIR Sensor incorporated within some variants of the enLink Zone Plus can be used to indicate occupancy status within an area. The implementation incorporates two incrementing counters PIR_COUNT and PIR_OCC_TIME to represent the occupied/unoccupied historical profile.
  • Page 14 PIR data transmission interval Depending on the enLink Zone Plus settings the PIR_COUNT and PIR_OCC_TIME messages will be sent at a fixed time interval or when the status changes (within constraints of the regulatory wireless duty cycle). In some applications it is useful to receive a wireless notification when the PIR state changes without waiting for the transmit interval.
  • Page 15 The Adaptive Max interval acts like a heartbeat, so if no change of PIR state occurs then a message is sent at the Adaptive Max interval. Press Enter when the key is correctly entered to return to the Quick Start Settings Menu. SYNETICA enLink Zone Plus User Guide Rev 1.6...
  • Page 16: Battery Installation/Replacement

    Battery Installation / Replacement enLink Zone Plus devices use 4 x SAFT LS14500 or EVE ER14505 AA size 3.6 Volt Lithium Thionyl Chloride (Li-SOCl2) batteries (non-rechargeable) or direct equivalent. No other batteries are approved for use in the device. Lithium Thionyl Chloride batteries have very high energy capacity and must be used and handled with care observing the guidance below.
