- Abstract
This study discusses an automatic hand washing system with water and liquid soap that comes out automatically. The results of this study are used as material for electronics training activities at high school level in the form of community service activities. This system can be applied to a place to wash hands in schools, colleges or malls. Water sources can be collected or directly using a water pipe, while liquid soap uses a bottle holder or the like. The water and liquid soap control system has a separate or separate circuit. The system for controlling water consists of an infrared sensor module which is applied as a proximity sensor, a relay module and a solenoid valve to open or close the water tap. The use of a solenoid valve when the water source uses a direct tap and the use of a water pump for the water source uses a reservoir. The system for controlling liquid soap consists of a proximity sensor module, a switching transistor circuit, and a mini DC submersible pump. All modules are tested to determine the characteristics of each module, so that you know the type of relay module and switching transistors to be used. The type of relay used is the active low type and the switching transistor type used is PNP. There were two systems that were tested, and they worked properly according to the original design, so it could be said that the whole system was working well.

Hasil penelitian ini sebagai materi untuk kegiatan pelatihan elektronika di sekolah tingkat SMA dalam bentuk kegiatan pengabdian kepada masyarakat. Sistem ini bisa diterapkan untuk tempat mencuci tangan di sekolah, kampus atau mall. Sumber air bisa dengan ditampung atau langsung menggunakan pipa air, sedangkan sabun cair menggunakan tempat botol atau sejenisnya. Sistem pengend
