Pedestal for AMS1117 for installation inside DW2-WiFi · 模型 30970
The Sonoff DW2-WiFi sensor operates on DC3V using 2x1.5V batteries (AAA 1.5V). This is an excellent product that accurately informs you when the door is opened or closed. However, in my usage environment, the battery runs out quickly. Therefore, I wanted to supply power from USB and convert the voltage to 3.3V inside the case to power the DW2-WiFi, so I used a small DC-DC step-down converter voltage regulator uxcell AMS1117 that can convert the voltage inside the case. In addition, in order to use this stably inside the case, we created a pedestal to fix the AMS1117 board.
