Consider a simple monitoring application where we use two nodes nl and n2. Each node when sensing temperature that is higher than 40°C raises an alarm (by turning
its red light on for 30msec), and at the same time sends an alert message to the
other node which turns its green light on for 20 msec. Each node takes a sample of
temperature every 10 minute.
We need to implement this monitoring system in nesc. Write the required module,
header and Makefile files. Show the final overall wiring diagram.
