QAR 24.00/ unit
Arrives by 17 October · Standard · Delivery from QAR 50
Express: 15 October · Economy: 21 October
Description
The Voltage and Current Sensor Module based on the MAX471 is designed for DC voltage and current measurement in embedded and Arduino-based systems. It supports current sensing up to 3A with a 1V/A output ratio and 2% typical accuracy. The onboard resistive voltage divider scales input voltage by a factor of 5, allowing safe measurement up to 25V when used with 5V ADC systems. With 10-bit ADC resolution, it enables precise monitoring of power consumption. Ideal for power analysis, battery monitoring, and load testing applications.
