Using this Gravity V2 Analog Voltage Divider is easy. First, connect it to your power source. Make sure the input voltage is within the range of 0.0245V to 25V. When connecting to an Arduino, keep in mind that the input voltage will be reduced by 5 times. Notice that the analog sensor port pin mapping has changed in the new version. For maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. The high - quality connector and immersion gold surface ensure long - term use, but handle it gently to prevent damage.
