    Wi-Fi SENSOR NETWORKING. The WSN802G is a 2.4 GHz IEEE 802.11g radio transceiver module that enables OEMs to build low-power wireless local area networking (WLAN) and sensor monitoring solutions for the global market.

    INTEGRATES GAINSPAN SoC. The WSN802G is the first Murata RF module to integrate the Gainspan GS1010 System on Chip (SoC).

    EXCEPTIONALLY LOW-POWER PROFILE. The WSN802G delivers an exceptionally low power profile and long battery life capabilities in a fully functional, certified radio module that is easily interfaced to existing 802.11b/g infrastructure for a wide variety of sensor monitoring and WLAN applications.

    SLEEP CAPABILITY. The Gainspan GS1010 SoC low average power consumption is obtained by putting the SoC to sleep between active periods. Depending upon the frequency of active periods, a single AA Lithium cell can provide a battery life in excess of 5 years. When the SoC is active, its current consumption is about 150 mA, allowing a battery to adequately power the device.

    I/O AND AUTO REPORT CAPABILITY. The WSN802G features Analog, Digital and Serial I/O with configurable automatic I/O reporting that includes interval timer, interrupt and ADC level triggers.

    SAME FORM FACTOR. At 1.05 sq. inch footprint, the WSN802G has the same form factor as Murata’s 802.15.4 LPR2430 series, wireless mesh XDM2140 series, and ZigBee ZMN2430 series modules.

    SAME PINOUT as Murata’s 802.15.4 LPR2430 series, wireless mesh XDM2140 series, and ZigBee ZMN2430 series modules.

    FCC / IC / ETSI CERTIFIED. The WSN802G is certified for unlicensed operation in the USA, Canada and Europe.
