Skywatch® IoMET

IoMET weather station

The IoMET measures wind speed, temperature and relative humidity. It has been developed for fine-grained outdoor weather measurements or for microclimatic conditions in greenhouses or vertical farms:

  • Une hélice omnidirectionnelle qui mesure le vent horizontalement et verticalement.
  • Protection anti radiation intégrée pour les capteurs d’humidité, de temperature et de pression.
  • Grande autonomie : deux ans d’utilisation continue
  • Rechargeable lithium-polymer battery
  • Easy to deploy: assembly in a matter of seconds
  • Robust, waterproof case
  • Panneau solaire pour une totale autonomie*
  • Capteur de rayonnement solaire (pyranomètre)*

* Options disponibles sur commande spéciale

  • Plage de mesure : Réponse spectral de 400 à 1150 nm
  • Résolution : 1 W/m2
  • Câblage : Connecteur 4 pôles
  • Unité de mesure : W/m2
  • Garantie : 2 ans

Applications

Technical data

The IoMET measures the following elements:

  • Wind speed
  • Humidity
  • Temperature
  • Barometric pressure

Data is transferred via LoRa over The Things Network and the packet format is as follows:

TTN

Each weather station has a serial number used as a unique identifier for the TTN.

The Deveui will be 0x31353430 + 4 bytes serial number.
For example, for an SN of 4000: DevEui= 0x3135343000000FA0

The AppKey can be configured by the user

The IoMET comprises the weather station and a mounting bracket that can be fixed to a perpendicular surface using screws or straps.

To attach the weather station to the stand :

  • Unscrew the heat shield from the humidifier sensor at the bottom of the appliance.
  • Drill a 12 mm hole in the bracket and feed the humidifier probe through the hole from above.
  • Replacing the heat shield

Maintenance

Opening the file

Access the micro-USB connector mounted on the board to configure and charge the device, unscrew the top screw and carefully remove the top section.

Closure of the case

Make sure the O-ring is clean and undamaged to prevent moisture penetration. Gently press the top half of the housing onto the bottom half.

Refit the top screw, making sure that it is tight (there is another O-ring between the top screw and the case) and that the circlip holding the top screw captive is intact.

Battery level

The battery level is sent by lora in a specific packet every 24 hours.

0 to 100% with a resolution of 1 LSB = 0.5%.

Plug in the micro-USB cable to recharge the battery. A full charge takes 3 hours. The charging indicator will remain lit until charging is complete.

  • You must first add your device to TTN
  • Go to applications
  • Create an application
  • In the application, go to End devices
  • Register the end device
  • Enter the given DevEUI and AppKey and click Register end device.
  • Open the upper housing
  • Connecting the battery
  • Now your data will be sent to TTN!
