DASUNG introduces the world’s first color E-ink monitor (Crowdfunding)

DASUNG e-Ink Color Monitor

Just a couple of years ago, we would have laughed at the idea of getting an E-ink monitor, because most displays were still in black and white only, larger displays were prohibitively expensive, and nobody wanted to wait for several seconds to get a full display refresh. But there’s been some good progress in recent years with color displays, faster refresh rate, and prices coming down somewhat which has led to the launch of devices such as the Onyx BOOX Tab Ultra C 10.3-inch color E-Ink Android tablet and a range of color eReaders such as the PocketBook Color. But DASUNG is going further with the launch of the world’s first color E-ink monitor. DASUNG E-Ink color monitor specifications: 23.5-inch color E-ink Kaleido 3 color screen with 3200 x 1800 resolution 4096 colors through DASUNG X-Color Filter “Ultra-fast Turbo Refresh Tech” Optional frontlight and/or curved display (depends on model) Landscape […]

Using SenseCAP T1000 LoRaWAN GPS Tracker for cattle tracking

SenseCAP T1000 Review Smart Agriculture Cattle Tracking

SenseCAP T1000 is a credit-size GPS tracker using LoRaWAN low-power long-range connectivity. Smart Agriculture is one specific application that can leverage IoT and LoRaWAN to analyze and manage soil, crops, and water, but also to track the location of livestock. This is an important aspect of farming, and we’ll use the SenseCAP T1000 LoRaWAN GPS tracker to track cattle in this article/review. SenseCAP T1000 unboxing The package contains the  SenseCAP T1000 GPS Tracker device, which is about the size of a credit card, and a charging cable.
