Avnet Introduces Indoor Air Quality Sensor HAT for Raspberry Pi for Rapid Prototyping

Technology solutions provider Avnet announced the availability of a specialized sensor HAT for Raspberry Pi. The Avnet-designed evaluation, development and quick-prototyping tool is intended for engineering professionals who need quick development of commercial, industrial, and heating, ventilation and air conditioning products requiring advanced indoor air quality measurement capabilities.

The HAT features an on-board calibrated Renesas ZMOD4410 sensor that measures the concentrations of total volatile organic compounds (TVOCs) from parts-per-billion to parts-per-million and can estimate carbon dioxide (eCO2) levels.
These are important indicators for monitoring indoor air quality. All sensors are electrically and chemically (gas) tested with lab calibration data stored in each ZMOD4410 sensor’s built-in nonvolatile memory.

n addition to the ZMOD4410 sensor, the HAT incorporates a Renesas HS3001 high-precision relative humidity and temperature sensor, along with software-controlled status LEDs. Connection points are also available to measure the ZMOD4410 active current consumption, which is useful when integrating the sensor and its software into products powered by extended life batteries.
