Development of constant-temperature-and-humidity test box used in medicament stability experiment / 医疗卫生装备

ABSTRACT

This article introduces a constant-temperature-and-humidity test box, which, with a high-performance Aduc812 singlechip as the core, is composed of an integrated temperature and humidity sensor, a serial keyboard controller and a lattice-style liquid crystal module. With balance control mode of temperature an d humidity, PID control, temperature and humidity decoupling applied, the high-r esponse-speed and high-precision control can be fulfilled.
