| Abstract: | A constant temperature control system is designed for microfluidic chip based on indium-tin-oxide(ITO) film.Temperature of ITO film is collected by a digital temperature sensor.USB interface communication is applied in this system.The temperature changes of microfluidic chip can be monitored by a PC in real-time.The target temperature can be set and stored.A method of improved algorithm of incremental PID control is used to control the temperature.The control precision of this system can achieve ±0.2 ℃. |
