MAX471 3A Current Sensor Module

Easily measure up to 3A of DC current with the MAX471 3A current sensor module from PMD Way, with free delivery.

This is a high-side device which can be used on (and powered from) voltages between 3 and 36V DC. 

The current measured it output as 1V per A, which can easily be measured by an ADC (Analog to Digital Converter) of a development board such as an Arduino, AVR, PIC etc.

For example, if you have an AVR 10-bit ADC running on a 5V system, you can measure down to (5/1023) 0.00489V ... so 1V/A gives us 4.89mA per division.  

Connection is simple:

• GND and OUT to GND and ADC pin respectively
• power supply (-) to GND
• power supply (+) to RS+
• load (-) to GND
• load (+) to RS-

Inline header pins and a screw terminal block are provided but not soldered to the board. 

Specifications:

• operating voltage - 3~36V DC
• sensitivity - 1V/A
• board measures 19.5 x 20.3mm
