HB100 microwave radar to Arduino

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object’s motion has altered the frequency of the returned signal. Doppler radar technology used to be expensive, but →

Struggling towards 5G | EDN

http://www.edn.com/electronics-blogs/5g-waves/4458307/The-struggle-to-5G?utm_content=bufferf9a50&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer  5G is developing so fast it’s hard to get a handle on it, whether you’re responsible for building 5G systems or writing about them. Part of the problem is that 5G is not one proposed standard, it’s a growing set of them.  Every new proposal of this sort complicates the ability of standards bodies →

IoTuesday: Maximize Your WiFi!

https://www.sparkfun.com/news/2363 Interesting looking project: mount the antenna and ESP8266 Thing Dev Board onto a pan/tilt bracket with some servos. The ESP8266 code was updated to connect to a WiFi access point (AP) and begin sweeping up and down (about 70°) and left to right (about 180°). At 5° increments, the ESP8266 would take an RSSI reading. Finally the antenna automatically returns →

LoRa for IoT

hen it comes to Internet of Things, connectivity to the internet is the primary area of focus.  The sensors on the IoT devices, wearables and electronic devices need to get connected easily – preferably wirelessly. IoT LPWA market is expected to grow at an annual rate of 90 percent. It is expected that in 2021 →

Sigfox for IoT

IoT LPWA market is expected to grow at an annual rate of 90 percent. It is expected that in 2021 the market size of about EUR 24.5 billion. SigFox and LoRa have been competitors in the LPWAN space for several years. There are LoRa and Sigfox networks in Finland -Sigfox network is operated by Connected →
