Voltage sensor 0 to 25volts FZ0430

The FZ0430 voltage sensor is a module that allows us to easily measure voltages up to 25V DC in an Arduino board or any device you want to measure. The FZ0430 voltage meter is a simple voltage divider with resistors of 30K and 7K5, which means that the voltage perceived by the module is divided by a factor of 5 (7.5/(30+7.5)).

The maximum voltage that we can measure will be 25V for a 5V (VDC) supply voltage processor and 16.5V for a 3.3V (VDC) processor. Exceeding this maximum voltage at the FZ0430 input will damage the Arduino analog pin. The resolution of the module measurement is 24.45mV. This sensor is very useful for measuring the state of a battery, checking the power of a 12V or 24V device, such as an LED strip, an electromagnet, a fan, or a Peltier cell for example.

Main features:

• Voltage input range: 0V to 25V DC.
• Detection Voltage Maximum input: 25V (5V x 5 = 25V) or 16.5V (3.3V x 5 = 16.5V).
• Voltage detection range: 24.41mV – 25V.
• Voltage analog resolution: 0.00489V DC.
• Minimum input detection voltage: 24.45mV (4.89mV x 5 = 24.45mV).
