PBH-104


PBH-104

PBH-104 is a programmable IoT device, which connects to the Internet via wired or wireless LAN. It supports various networking and security protocols, and encryption algorithms.
It is equipped with four serial interfaces to connect and communicate with sensors or equipment which support RS232, RS422, or RS485. This allows you to collect data from serial equipment/sensors and send it to various systems through the Internet, and vice versa.
PBH-104 is embedded with a PHPoC interpreter, letting you pre-process data as you want before exchanging by writing a simple PHPoC script. It is very flexible to create customized devices to meet the diverse needs.
Moreover, PBH-104 comes along with an embedded web server, letting you do system setting or other tasks via web browser.
