ご注意

商品画像は参考イメージです。
実際の商品は、出荷時の製品を基準とします。

モニターや照明環境により、実際の色味が画像と多少異なる場合があります。
また手作業による測定のため、1~2mm / g程度の誤差が生じる場合があります。

製品説明

本モジュールは 抵抗分圧回路を利用した電圧検出モジュールです。
入力電圧を 1/5に分圧してArduinoなどのマイコンで測定できるようにします。

Arduinoのアナログ入力電圧は 最大5V のため、
本モジュールの最大測定電圧は

5V × 5 = 25V

となります。

3.3Vシステムの場合は

3.3V × 5 = 16.5V

までが最大測定電圧となります。

ArduinoのAVRマイコンは 10bit ADC(アナログデジタル変換) を使用しており、
アナログ分解能は

0.00489V(5V / 1023)

となります。

そのため本モジュールで測定可能な最小電圧は

0.00489V × 5 = 0.02445V

です。

技術サポートに関する注意

本製品は電子工作向けのモジュール部品です。

技術サポート・回路説明・接続方法のサポートは行っておりません。

電子回路の知識がある方のみご購入ください。
※商品の初期不良のみ交換または返金対応いたします。

International Shipping Methods

Notes:

  • The billing weight will be based on whichever is greater: the actual weight or the volumetric weight.
  • Volumetric weight (kg) = Length (cm) x Width (cm) x Height (cm) / 5000
  • Common oversized and heavy items include: furniture, fishing rods, automotive parts, etc.
  • Consolidating 2 or more items will incur a "consolidation handling fee" (see price list for details)
    

Platform Transaction Rules:

1. Order cancellations and returns are not accepted for any reason. Please review the item description and seller ratings before purchase.
2. Each mercari item is shipped individually. Orders from the same seller will be processed separately, resulting in multiple handling fees and local Japanese shipping charges. Combined shipping is not available.
3. As mercari does not have a negotiation system, we cannot provide price negotiation services.
4. We cannot assist with purchases for items marked as "Buyer Specified," "Bundle Deals," "Requires Buyer's Agreement (Not Buy It Now)," or "Partial Shipping of Order."
5. Buyers cannot demand specific shipping methods from sellers. Shipping will be as per the seller's offered options.
6. Requests for early shipping, post-purchase price reductions, or transaction cancellations after purchase cannot be accommodated.
7. Once items arrive at our Japanese receiving point, buyer feedback must be provided and payment released to the seller. Feedback cannot be modified, and negative or no feedback is not permitted.
8. Refusal of items is not allowed after they arrive at our Japanese receiving point.
