Các bước tiến hành: Bước 1: Tìm hiểu sơ đồ lắp ráp Nghiên cứu sơ đồ nguyên lý và sơ đồ lắp ráp của mạch điện để hiểu rõ cách kết nối giữa các linh kiện. Bước 2: Chuẩn bị thiết bị, dụng cụ và vật liệu Chuẩn bị mô đun cảm biến (ánh sáng, nhiệt độ hoặc độ ẩm), phụ tải (bóng đèn, quạt, còi...), nguồn điện (pin, adapter), dây dẫn và các dụng cụ như kìm tuốt dây, tua vít. Bước 3: Lắp ráp mạch điều khiển Kết nối cảm biến: Cắm cảm biến vào mô đun (nếu là cảm biến rời). Kết nối phụ tải: Nối thiết bị tiêu thụ điện vào đầu ra (Output) của mô đun cảm biến. Kết nối nguồn: Nối nguồn điện vào các cực nguồn (thường ký hiệu là VCC và GND) của mô đun. Bước 4: Cài đặt mức ngưỡng (ngưỡng tác động) Điều chỉnh biến trở trên mô đun để xác định mức độ cảm biến sẽ kích hoạt mạch (ví dụ: trời tối đến mức nào thì đèn sáng). Bước 5: Kiểm tra và vận hành Cấp nguồn và thử nghiệm mạch bằng cách tác động vào cảm biến (ví dụ: che ánh sáng hoặc làm nóng đầu dò) để xem mạch có hoạt động đúng yêu cầu hay không.
