In remotely deployed Wireless Sensor Networks (WSN) software faults may occur due to sensor nodes process failures. Fault diagnosis remains a challenging task due to physical inaccessibility of sensor nodes, energy constraints and varying application requirements for latency and reliability. WSN once deployed resort to fault management mechanisms to ensure continued operation. While fault detection...
In this paper a wireless based scheme has been proposed for monitoring of temperature and humidity. A highly sensitive signal conditioning circuitry for capacitive humidity and resistive temperature sensors have been developed. The humidity and temperature sensed by these sensors are converted into square waves of central frequencies 101 kHz and ∼9 kHz respectively. The sensitivities obtained are...
