The Eastsun E-W21 (digital price tag) is the cute size ESL epaper tag, which is made of 2.1” inch HD eink with 111 DPI high resolutions, which’s more suitable for warehouse, shelf, stock, inventory, sign.
Industrial-grade AP Station:
Eastsun industrial-grade AP Station (Base Station) E-WA01 adopts the enhanced 433MHz transmission module and newly-designed PCB board, so the signal radius coverage reaches 80-500 meters under different conditions, and the updates rate is increased by 250-300%. In addition, 433MHz has the unique characteristics of wall penetration and anti-EMI (electromegnatic interference), which is beyond 2.4GHz (Bluetooth / Zigbee).
Why the Eastsun 433MHz transmission technology:
1. Wider signal radius coverage: transmit data upto 30 - 80 meters radius area (the whole area is the range of 2800-20000m²) under different indoor conditions.
2. Stronger wall penetration: The ouput power of the industrial-grade 433MHz AP station is 36 dBm, which is suitable for complex situations such as warehouse, production line, hospital, but 2.4GHz (Bluetooth / Zigbee) doesn't have this characteristics.
3. Anti-EMI (electromegnatic interference): ensures working well under the situation of multiple equipments.
How the Eastsun 433MHz ESL system work:
The Complete ESL system combines esl labels, AP station and software. The Eastsun ESL system not only run indepently, but also integrate other systems to run together. By LAN/WLAN, the AP station conntects PC terminal or cloud server, and transmits data to each esl labels through 433MHz frequency, and every data will be recorded by information monitor.
