Well.....the sensor from Sensirion is not a capacitive sensor.If I use it I will have to change the whole circuit.

https://www.digikey.com is a great source for components, they carry the Humeriel sensors. It sounds like you're outside the US, I think they ship internationally.

Hiya Pranav,
A few months ago I got some samples from dallas, the (ds1923 I'button) to be precise. Along with a pic I've set the I'button to take temp & humidty readings for 6 months then when I've made up a simple VB program to read it I'll read it and chuck it outside again. Those I'button's are the go mate try and get some.

Cheers Bryan

No,I dont think so.

BTW,guys I am now building a microcontroller based LPG steam bath controller.I will upload the crude circuit diagram of the same once I design it.

Take care dudes,

Humidity Measurement Circuit

I need to design and develop a circuit for humidity and temperature measurement on LCD or LED display. Please suggest me the circuit and its components. I know the humidity meters are available in the market. But i need to develop it myself.

You can build a wet/dry bulb humidity sensor.
