    Abstract
    This research aims to develop the test, the quality of the water timber with a wireless sensor network. The monitoring of water quality the rubber, the sensor is applied to test the quality of the water timber to be created the density of the water timber with ultrasonic waves by the calibration the reflection of sound waves on moving the boundaries of the medium with impedance deluxe sound different ratio of amplitude of the waves crash against the waves reflected back No. 1 (A0 / A1) was 0.99 makes the density of the water timber (% DRC) or ρ2 of 85.70 with a frequency of 46 kHz to develop a series of quality tests that rubber has conducted research comparing the measurement volume. Traditional meat timber used to block metro lactate measurement meat quality latex rubber developed the electrical resistance the measurement meat old used rubber sticks metro lactose. The percentage of error was 102% compared by water quality rubber built with an equal percentage 73% measurement accuracy compared with the metro bar, with a series of quality test rubber built. The results of the water timber species RRIM600 and RRIT251 a percentage of the estimated moving average of 16.12 and 26.15 respectively measurement reproducibility compares the results of the water timber with sticks and the metro to test water quality timber built samples from each timber of 10 samples were measured in duplicate samples 5 times the results of the water timber species RRIM600 and RRIT251 percent average error of 16.27 and 26.15 respectively.
