Proposed functionalityProposed functionality Sensor nodes will sense the temperatures and Sensor nodes will sense the temperatures and

compare them to an established threshold compare them to an established threshold If a sensed temperature is above the threshold, it will If a sensed temperature is above the threshold, it will

send an alert to the base and raise the fan speed on send an alert to the base and raise the fan speed on the systemthe system

If a sensed temperature is below, it will send an alert If a sensed temperature is below, it will send an alert and lower the fan speedand lower the fan speed
