| Abstract: | An intelligent density measurement device was designed.The system converted analog signals to digital signals through ADHX711.Using AT89S52 as the control center,real-time control of the chip was achieved,and the status of the keys were showed on the indicator.The temperature of the water was detected by self-made digital thermometer and the water density was determined.The weight of the object in water was measured by a pressure sensor.After data processing with master chip microcontroller,the density of the object was measured accurately. |
