WeBee3 [1] is a miniaturised, battery operated sensor for less than €10. The heart of the IEEE 802.15.4/ZigBee hardware node is a CC 2431 type SoCfrom TI/Chipcon. The onboard ZigBee stack allows to fully integrate WeBee3 as an end device into ad-hoc mesh networks. As a temperature sensor WeBee3 can work for over 10 years without replacing or recharging the battery.
