The QCIOT-HS4001POCZ board enables quick prototyping of the HS4001 High-Performance Relative Humidity and Temperature Sensor in a custom system design. The board provides a standard Pmod™ Type 6A (extended I²C) connection for the onboard sensor to plug into any desired MCU evaluation kit with a matching connector.

The QCIOT-HS4001POCZ features Pmod™ connectors on both sides of the board to allow additional Type 6/6A boards to be connected in a daisy-chained solution with multiple sensors on the same MCU Pmod™ connector. Software support present in the Renesas IDE (e² studio) provides code generation to connect the sensor and the MCU, thereby significantly reducing development time. Thanks to the standard connector and software support, the QCIOT-HS4001POCZ is ideal for Renesas’ QuickConnect IoT to rapidly create an IoT system.


  • Relative Humidity HS4001 sensor sample mounted:
    • RH accuracy: ±1.5%RH
    • ±0.2 °C, typical (-10 °C to +80 °C)
    • Very low current consumption: 0.3μA average (8-bit resolution, 3.3V supply)
  • Standardized Type 6A Pmod™ connector supports I²C Extended interface
  • Dual connectors allow pass-through signals for daisy-chained solutions
  • Software support in e² studio minimizes development time with one-click code generation
