Multisensor

The n-fuse Multisensor is a compact LoRaWAN and NFC-enabled IoT sensor device capable of measuring five environmental and physical parameters. It integrates the HDC2080 for temperature and humidity sensing, BMA400 triaxial accelerometer for motion detection, SFH7776 for ambient light measurement, and a magnetic field-sensitive reed switch for magnet sensing. The device features an IP54-rated enclosure and is designed for ultra-low power consumption to enable battery life of 10+ years.

Thinger.io Integration

This device communicates via LoRaWAN, enabling seamless integration with Thinger.io through a LoRaWAN Network Server. The Multisensor supports threshold-based triggers for temperature, humidity, motion, and ambient light, allowing the device to transmit data only when specific conditions are met.

Requirements

A LoRaWAN server is required to communicate the n-fuse Multisensor into Thinger.io, some options are:

Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.

Get Started

Installation

Look for the plugin in the Thinger.io Plugin Store and install it in your Thinger.io instance. Once the plugin is installed a new Product will be created for this device.

Configuration

The Product is already preconfigured, check that the auto provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your desire.

Usage

Start sending uplinks for autoprovisioning devices and buckets. This product also provides a predefined dashboard and downlinks.
