Wireless IoT Sensors For Temperature, Humidity, Light and Motion
Droplet Sensor
The Droplet is Nube iO’s very own LoRa IoT sensor, which has been built to address the problem of wanting multiple points of data capture with minimal time for install and wiring. LoRa wireless IoT sensor technologies requires less power, meaning it can be battery powered using AA batteries. This technology is more reliable in communicating information to the receiver than regular WiFi.
As sensors are wireless, Nube iO droplets can be easily installed on any surface to collect multiple data points. The receiver then aggregates, interprets, and sends this information over to a local or cloud server.
Nube iO droplet wireless sensors are currently available in three models. These models include:



Wireless LoRa Transmission
2KM Range
Fast Install
7+ years life span
Temperature, Humidity, Light & Motion Monitoring

- Wireless IoT sensors come in 3 models with features temperature, humidity, light and motion
- Monitor environment conditions and know when people enter your building
- Fast and simple installation
- Transmission range: 2km line of sight or 100m in a dense environment
- Power: Battery powered using 3x AA batteries
- Transmission protocol: LoRa transmission (868/915Mhz)
- Life span: 7-10 years dependent on push rate and environmental condition
Key Uses For Environmental Wireless Sensors
- Remote visualisation of building environments
- Improve comfort conditions in buildings
- Motion sensors detect after hours entry
- Motion sensors detect movement and trigger HVAC and lighting
- Compare environmental data with scheduled set point to test HVAC efficiency
- Receive status of HVAC and lighting

Why LoRa
LoRa is a low-power, long-range wireless technology designed for the Internet of Things. It is less affected by buildings and other obstructions than regular WiFi, with one gateway generally being able to provide coverage for a 70x70m 3-story building.
LoRa is expected to hold 75% of the IoT device market share soon. The LoRa community is expanding rapidly, with many new contributions and developments occurring every day.
Considering LoRa transmission messages are very small, around 50 bytes, less power is required than say to make a phone call or upload a photo. Using LoRa, our sensors can achieve a 5+ year battery life when pushing data once a day. Alternatives either cannot transmit the required distance, or are too costly to do so.
LoRa runs on a low radio frequency, which enables the transmission to penetrate common building obstacles such as furniture, walls, pipes and even concrete. Our LoRa Raw devices can transmit around 100m in a commercial building, which is impressive considering the weaker penetration of WiFi.
The LoRa community is very active and open, comprising of companies and individuals who are further developing LoRa and LoRaWAN. Because of this, the technology is constantly improving and there is lots of available support online and through forums. This is different from legacy, proprietary software.
