The A201 flexiforce sensor has been characterized for rainfall measuring instrument. The flexiforce has been used as a sensor to measure the variation of the water mass in the form of water volume. The sensor response in resistance variation to the water volume is very sensitive with a gradient of 7.3 mOhm/ml. Voltage response of the sensor due to the effect of changes in pressure caused by variation in the volume of rainfall is processed into precipitation data using ATMEGA32 microcontroller. Rainfall data is displayed on a Liquid Crystal Display (LCD ) and stored in a Micro Secure Digital (Micro SD) with delay for 6 seconds. The resolution of instrument is up to 5 ml volume variation, that is equivalent to the value of the precipitation of 0.28 mm.
