Abstract: The present paper reported a system for simultaneous measurement of humidity and temperature, employing a capacitive humidity sensor and a thermistor placed in a 555 linear circuit operating in the astable multivibrator mode. The output of the circuit, after further conditioning, is processed by an appropriately trained artificial neutral network (ANN) to yield the % relative humidity and temperature values. The efficiency of the system has been tested by numerical simulation studies. The versatility of the arrangement from the point of view of accuracy and cost-effectiveness has been established by comparison with other reported schemes for humidity and temperature measurement.

 

Keywords: Capacitive humidity sensor, Thermistor, Artificial neutral network, 555 timer
