Cellular-enabled IoT is here — and it’s making long-range connectivity easier and more affordable than ever. Here’s Ubidots’ top 6 affordable cellular IoT hardware devices.  Continue reading “Top 6 affordable cellular IoT hardware devices”

Atmospheric data collection using High Altitude Balloons, Linkit One and Ubidots

During the contest Smart devices for Smart Cities, launched by Mediatek Labs, this team of aerospace engineering students setup a Linkit one to log atmospherical data to Ubidots as it went up.

The balloon would collect atmospheric data such as temperature and hydrogen concentration, with the help of a High Altitude Balloon, Linkit One and Ubidots. To see their project in detail, check out their entry in our Hackster hub:

Linkit One WiFi Battery Test

In most IoT projects, your sensing device is likely to be left unattended for a few months or even years. This is why power consumption is an important factor when selecting your IoT hardware platform.

In this test we explored how many times a Ubidots variable can be updated using Linkit’s WiFi with the 1000mAh battery it ships with. If the module goes into deep sleep between every post, then it would last quite long with a single battery charge:

8.3 hours

if you send data every second

20.8 days

if you send data every minute

3.4 months 

if you send data every 5 minutes

3 years! 

if you send data every hour!
