Design of wireless data transmission tool using XBee

Temperature and humidity are important things tobe considered because they can be sensitive things to fulfill for certain conditions. To reach the certain conditions, both of them must be set in certain values to fulfill. Aim of research is to design a tool that can detect the of temperature and humidity from a box of eggs hatching and send the data readings wireless using XBee. The results of temperature and humidity are transmitted from different place to another in different distances from 1meter-50meter. DHT22-Sensor is used to detect temperature and humidity of eggs hatching box. All data are processed of ATMega-328P send it through XBee-Transmitter and XBee-Receiver, before display it on a monitor. In data transmission, system uses 9600kb/s baud rate. If temperature reading of DHT22-Sensor in range from 37.90C-38.60C and 50%-60% for range of humidity, so both of values are in set value. All of data detection are validated with Digital Sensor and Hygrometer. From results show that the range differences of temperature readings are 0.1oC-0.5oC, while humidity readings are 1%. All the results can be accepted because the different data are small and have no effect when those are applied to hatching box.
