Measurement and control of environmental variables such as temperature and relative humidity have a significant application in science, industry, agriculture, healthcare and controlling and automation technological processes. These two environmental parameters are critical to continuously measure and keep in desired ranges for real working conditions. This paper aims to obtain the values of temperature and relative humidity via wireless communication which is one of the most common communication methods. The transmission of the data was performed using RF receiver and RF transmitter modules. The SHT11 sensor was used to measure both temperature and relative humidity of the environment for the same point. This application is realized and successfully tested in this study. The transfer of data to the computer is successfully provided. Obtained results can be used and applied to increase a system’s life in automation and control technologies.

In almost all areas of the life-cycle, measurement, contolling and even achieving in stable/desired values of temperature have big importance. The man-kind’s daily activities are influenced by various control systems in almost every direction. Also, control systems are widely used in all sectors of the industry. This study mainly focused on measuring and controlling the temperature values. The purpose is to keep stable the analog temperature data at the desired temperature by performing the necessary control procedures. In designed temperature control system, analog temperature values were measured by K type thermocouple. Since the temperature measured by the thermocouple is in the mV level, this data must be raised to 0-5 V to be supplied to the Arduino analog input (A0). The AD620 instrumentation amplifier was used for the upgrade. The digital output data from the Arduino PWM3 block is transmitted to the SSR (Solid State Relay) using the 74HC244 buffer. Temperature control was performed by the PID control software preparing in the LabVIEW program. In this study, temperature values are successfully obtained with a ±%1.5 accuracy via Labview.
