Development Of Ni-Zn Ferrite Based Smart Humidity Sensor Module By Using Mixed Signal Programmable System-On-Chip
Synthesis of materials for sensor and development of smart sensor module,of promising characteristics,large adoptability and great portability,plays significant role in designing of sophisticated instrumentation.Therefore,based on an innovative technology,analogue and mixed signal VLSI design,a smart humidity sensor module is designed and presented in this paper.The composition of nano sized Nickel-Zinc ferrites are synthesised by co-precipitation and formation of single phase spinel ferrites are confirmed by X-powder diffraction.The inter-digitated sensor is fabricated by screen printing technique and implemented for sensor module development.The electrical resistance (R),measured against humidity shows exponential decrease with increase in the humidity (RH %) and supports the photonic conductivity.This nature of the sensor is considered for designing of sensor module.A programmable System on-chip,Cypress PSoC,emphasizes mixed signal VLSI technology.The sensor under investigation is interfaced to the cypress PSoC.On reconfigufing the analogue as well as digital parts a system on chip is designed.The system is calibrated to RH%.Actually,the sensor materials are exhibiting semiconductor nature.The exponential behaviour of the sensor material is linearised by deploying the features of the firmware.The present sensor module is showing humidity reading in RH% with great accuracy.It also provides linear response during humidity 30 RH% to 95 RH%.This low cost and high reliable sensor could be utilized for monitoring relative humidity different environment.
