4-20mA to 5V Converter for Arduino Industrial Sensors
4-20mA to 5V Converter Module for Arduino & Industrial Sensors
This module converts standard 4-20mA current loop signals from industrial sensors into a clean 0-5V analog voltage that any microcontroller like Arduino can read directly. It is ideal for connecting pressure transmitters, temperature sensors, or PLC analog outputs to your prototyping setup, eliminating the need for complex external circuitry.

What You Can Build With This
- Industrial pressure monitoring system with Arduino
- Water level sensing using 4-20mA transmitters
- PLC analog output testing and calibration
- Temperature monitoring with RTD or thermocouple transmitters
Compatibility
Compatible with any 5V microcontroller like Arduino Uno, Mega, or Nano. For 3.3V boards such as ESP32 or Raspberry Pi Pico, use a voltage divider or level shifter to scale the 5V output down. Pairs directly with 4-20mA sensors: pressure transducers, level sensors, and temperature transmitters.
Wiring Notes
Connect the sensor's 4-20mA positive wire to I+ and negative to I- on the module. Supply the module with 7-24V DC to VCC and GND. The Vout pin provides 0-5V analog output proportional to the input current—connect it to any Arduino analog input pin. No pull-up resistors needed; the module uses an internal 250Ω sense resistor.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, it outputs a 0-5V analog signal that connects directly to any Arduino analog input pin. No additional drivers required.
Can I use this with a 3.3V microcontroller?
You'll need a voltage divider or level shifter to scale the 5V output down to 3.3V maximum for safe reading. A simple 10k/20k resistor divider works well.
What sensors can I connect?
Any industrial sensor with a 4-20mA current output: pressure transmitters, flow meters, level probes, or temperature transmitters with built-in 4-20mA loops.
