数字式蜂蜜含水率检测仪设计
Design of Digital Honey Water Content Meter
摘要
Abstract
In order to offer a meter with the characteristics of easy taking, quickly measuring, high precision, being suitable for online detection, and overcoming influence of temperature on measurement for honey water content detection, based on the experiment and electrical conductivity detection principle, a honey water content meter was designed. Firstly, yellow-locust honey was used to establish the mathematical model among water content (17% -34% ) , temperature (5 ~40℃ ) and electrical conductivity. Then the hardware was designed with single chip micro-computer ( SCM ) of 8 bits as controller, DJS - 1 electrode and DS18B20 as sensors of electrical conductivity and temperature, respectively. The software was programmed with C language of SCM. The detection results showed that the measurement time of one sample was within 3 s and the precision was ±0. 5% .关键词
