High precision, low pressure sensor

[varunme]

what is the best sensor that can be used for sensing pressure of the order of 1atm , i want to measure the pressure of a cylindrical ballon like object that grows , i want to calculate the pressure builds there

have a look at sensirion's sensors
Relative Humidity Sensor, Gas Flow Sensor, Mass Flow Sensor and Liquid Flow Sensor Solutions - Sensirion AG

These are highly priced , does these needs anymore interfacing with an uc to connect to PC ? ,
Does anyone knows low priced ones ?

You have the options relative (to atmosphere) or absolute pressure sensor. And should decide about required accuray and long term stability.

Fujikura do a range of pressure sensors that might suit.
cost around the £3 mark for one off.
