Superior performance for optimal LoRaWAN® data transmission

Multi-band LoRaWAN transceiver

With the Nexelec TOUCH application and NFC technology, you can quickly and easily configure the product to transmit on the frequency of your choice: Europe (868MHz), USA (915MHz), Australia (923MHz), etc.

No more data loss!

Historical Data mode + Redundancy function: measurements can be grouped in a single LoRaWAN frame to limit the number of radio transmissions and are sent 3 times to maximize their reception by the network gateway.

Optimized PCB radio antenna

Designed to ensure reliable radio connectivity, even in harsh environments, while limiting power consumption to extend battery life

Enhanced cyber security

Data transmitted by the product is secured from end to end using double AES128 encryption.

QR'LOOK simplifies the use of room sensors

Are you deploying thousands of sensors on your property, and want to make your residents aware of how to use room sensors?

Enhanced security

QR'LOOK is a QR Code label to be stuck near the sensors so that occupants can learn how to use them optimally thanks to our advice

Information always at hand

Occupants simply scan the QR Code to access an online web page containing all the information they need on their sensor: operation, use, maintenance, downloadable instructions, videos, etc.

Frequently Asked Questions

Our experts answer your questions

Moisture comes from a variety of sources, including human activity, breathing and architectural design problems. Air that’s too dry dries out the respiratory tract, and humidity that’s too high promotes allergies. Ideally, the humidity level in an enclosed space should be between 40% and 60%.

NFC (Near Field Communication) is a magnetic field technology used to exchange data between a product and a smartphone.

To configure the product, simply :

  • Download the free Nexelec TOUCH application from Google Play Store or Apple App Store
  • Select product and follow application instructions
