Minimal off-chip components are allowed in this implementation for improved user experience, which are antenna, crystal resonator and supply decoupling capacitors. Low-power low-voltage design techniques such as sub-threshold design were employed intensively to minimize the power consumption of the sensor node IC and maximize the battery life.
