Abstract :
In this paper, the development of PIC based sensor system for sympodial orchid stem measurement is presented. The humidity sensor, temperature sensor, light sensor and stem detection sensor are integrated with the PIC16F887. Here, the stem detection sensor was developed by using 2mm Aluminium type strain gauge that connected in Wheatstone bridge form. The correlation between the strain gauge output and the given constant displacement produced a good relationship. Then, results attained proven that the proposed system is capable to measure changes of sympodial orchid stem diameter.
