| Abstract: | To control the heating temperature in acid-fast staining experiment,a kind of constant temperature controller is designed and made.The controller uses STC89C52 as main controller,DS18B20 as temperature measuring,and adopts proportion integration differentiation(PID) algorithm and pulse-width modulation(PWM) output to control triac turning on and off.The practical using results showes that the controller is able to control temperature constantly within fixed time and temperature,with accurate and stable cont... |
