- It has been designed and realized the system settings for temperature and humidity in the greenhouse plants based Borland Delphi 7.0. The main obstacle in the agricultural sector to provide raw materials for industry is the lack of agricultural land in Indonesia, these problems can be overcome by using a greenhouse equipped with setting physical parameters such as temperature and humidity required in the plant. For setting the temperature and humidity of the air in the system using a microcontroller ATmega8535 as serial data transmission device to the computer. As used SHT11 humidity sensor. The output of the sensor directly sent to the microcontroller ATmega8535 on pins A0 and A1. Measured data from the sensor is sent serially to the computer using the RS-232 protocol. From the research that has been done, Borland Delphi 7.0 is obtained that can display the measured data from the sensor SHT11 humidity in the form of air humidity and temperature graphs over time and is capable of storing the data in the table settings contained in Microsoft Access. From the results of the testing instrument setting temperature and humidity in the greenhouse can be used with a range between 35◦C and 25◦C-humidity of 35% -80%. The tests are performed with standard measuring tool is a tool-hyrgometer thermometer and test results obtained quantitatively.
