DFRobot Gravity Analog Current to Voltage Converter (for 4~20mA Application)
Couldn't load pickup availability
The Gravity: Analog Current to Voltage Converter is a versatile module designed to bridge the gap between industrial equipment and hobbyist electronics. This current to voltage converter linearly transforms 0-25mA current signals into 0-3V voltage outputs that can be easily read by microcontrollers like Arduino.
Industrial sensors and devices typically output 4-20mA current signals, which standard microcontrollers cannot directly interpret. This industrial sensor interface module solves that problem by converting these signals into voltage readings that any analog input pin can process. The module's wide detection range of 0-25mA makes it particularly useful for fault diagnosis (below 4mA) and overrun detection (above 20mA) applications.
What makes this 4-20mA signal converter stand out is its combination of high precision and ease of use. The module uses a 0.1% high-precision sense resistor paired with an ultra-low noise rail-to-rail zero-drift operational amplifier, ensuring accurate readings without requiring calibration.
With measurement accuracy of ±0.5% at 16-bit ADC resolution, this module delivers reliable data for critical applications. The wide supply voltage range of 3.3V to 5.5V ensures compatibility with various development boards, while the standard Gravity 3-pin interface makes connections simple and straightforward.
Whether you're working on Arduino current measurement projects, industrial automation, or sensor integration, this converter provides a reliable bridge between industrial standards and DIY electronics.
