This module is a member of the IoTextra series, which serves as a fundamental building block of our ecosystem and embodies the Make Things Happy Philosophy. It is engineered to bridge the gap between rapid prototyping and industrial-grade reliability.

Hardware Synergy: The module is compatible with both IoTsmart and IoTbase series.

Software Power: This hardware compatibility unlocks the full potential of the IoTflow platform. It enables you to:

  • Create custom Node-RED nodes effortlessly.
  • Integrate via MQTT with third-party global platforms like Blynk.
  • Scale your project from a single node to a complex industrial network.

Key Specifications

  • Size: 47 × 56 mm, with mounting holes for base-module or Raspberry Pi installation

Operation Modes

🔌 Standalone
Analog readings are available via the I²C bus, through the HOST connector or the Qwiic connectors. The ADC ALERT/RDY signals are routed to the HOST connector.
🧠 Smart
An IoTsmart module is inserted vertically into the HOST connector. Analog data and the 5V module supply are provided through HOST, powered from the IoTsmart module.
🏗 Mezzanine
The module is installed into an IoTbase carrier board. Analog data and the 5V module supply are provided through HOST.

Applications

🏭 Industrial Process Monitoring
Measures 4-20mA transmitter outputs from pressure, temperature, and flow sensors, or reads 0-10V analog signals directly — no external signal conditioning needed thanks to the onboard PGA and precision voltage reference.
🤖 Robotics & Lab Automation
Captures voltage and current outputs from bench power supplies, sensor calibration rigs, and test equipment across four independent differential channels — 16-bit resolution and selectable gain suit precision lab measurements.
🌱 Smart Farming
Reads 4-20mA soil moisture, pH, or EC sensors alongside 0-10V feedback from irrigation valve actuators — differential inputs reject common-mode noise from long field wiring runs.
🏠 Smart Home & Consumer Electronics
Monitors battery charger voltage/current curves, appliance sensor feedback, or infotainment system analog inputs — configurable per-channel voltage or current range covers most consumer sensor interfaces.
