WSN24 wireless module

WSN24 wireless module is mainly for sensor equipment and instrument manufacturers. Users can directly embed WSN24 wireless sensor module into equipment and instrumentation to make the existing equipment network , wireless. Standard wireless module provides industry standard RS-232 interface and other interface converter can be arbitrarily set in accordance with users' requirements. communications transmitted using the IEEE 802.15.4. Sensor equipment and instrument of the wireless network can be greatly upgrade existing equipment and instrumentation sensors and grade level. Accompanied by a wireless router and server can be a complete wireless data transmission and control of wireless sensor networks. Have wireless-enabled products on site is very convenient, and removed the integrated wiring problems.
