Wireless Sensor Network

Ultra-low power consumption wireless wireless sensor sensor network network system system SENSbee enables ultra-low power wireless sensor network development. Flexible, barely intrusive and low-cost systems are possible due to SWAN technology, property of SAYME. SENSbee wireless sensor modules allow remote and distribuited monitorization of multiple variables during long periods of time.

SAYME offers an end-to-end solution; from the sensor and its signal conditioning to the web monitoring software, including the ultra-low power consumption electronics.
