Conclusions

In this study, the humidity measurement and control system has been developed to control the humidity level of the incubator environment.  Since  the  humidifier is an active humidifier, high humidity levels are easily provided even at an ambient condition. In addition to these, temperature is one of the control parameters not affected by the humidifying processes. The IC-type humidity sensor is used in the humidity measurement circuit. Since the linearity of the sensor is better, accuracy is higher, the response time is faster than the other humidity sensor, and the RH of the incubator environment is controlled with small fluctuations around the control values. Since, measurement and control processes are achieved by the high-performance and high-speed PIC microcontroller, it is possible to provide  better performance to  control.
