Renesas Air Quality HATs

Avnet's Renesas ZMOD4410 and ZMOD4510 Air Quality HATs for Raspberry Pi are evaluation, development and quick-prototyping tools intended for professionals developing a wide variety of Air Quality monitoring capabilities.

Benefits

• Convenient Raspberry Pi HAT form factor for evaluation, development and quick prototyping of products that monitor air quality
• Sensors are chemically tested and factory calibrated
• On-board user-adjustable power supply option and current measurement connection points
• Configurable alarm/interrupt output
• Supplied with pre-compiled Raspberry Pi OS test / validation application
• Licensed downloadable compiled code offered by Renesas.

Validating the Renesas ZMOD 4410 and 4510 HATs operation with a Raspberry Pi:

1. Download the “out of the box” test/validation application, a pre-compiled test application built with algorithm libraries which runs under the Raspberry Pi operating system (formerly Raspbian).
2. View the Tutorial demonstrating the measurement of Total Volatile Organic Compounds (TVOC).

Renesas Algorithm libraries 

• Algorithm libraries developed by Renesas are required to operate the sensors. These algorithm libraries are not included with the HAT but are available directly from Renesas subject to the terms and conditions of Renesas’ Software License Agreement. An application for the Software License Agreement, along with the procedure to download the algorithms and related confidential data, is available here.

Avnet's Renesas ZMOD4410 Indoor Air Quality HAT

Avnet's Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi is intended for professionals developing a wide variety of wall-powered and battery-powered products with indoor air quality monitoring capability. The HAT features an on-board calibrated ZMOD4410 sensor that measures the concentrations of Total Volatile Organic Compounds (TVOC) and can estimate carbon dioxide (eCO2) levels. These are important indicators for monitoring indoor air quality.

In addition to the ZMOD4410 sensor, the HAT incorporates a Renesas HS3001 Precision Relative Humidity and Temperature Sensor, along with software-controlled status LEDs.

In certain applications, it may be desirable to shift the ZMOD4410 sensing element’s chemical selectivity and sensitivity, or to model its operation at supply voltages other than 3.3V. The HAT facilitates this with a user-adjustable power supply; a jumper selects the default fixed 3.3V supply or one which can be set from 1.75V to 3.9V. The HAT also provides connection points to measure the ZMOD4410 current consumption. This may be useful when integrating the sensor and its software into an extended-life battery-powered product.

Target applications:

• Smart home appliances
• Smart thermostats
• Smart speakers
• Smart fans
• Smoke alarms
• Vacuum cleaners
• Garage openers
• Security systems
• HVAC controls
• Air purifiers
• Building automation

Avnet's Renesas ZMOD4510 Outdoor Air Quality HAT

Avnet's Renesas ZMOD4510 Outdoor Air Quality HAT for Raspberry Pi is intended for professionals developing applications for monitoring and reporting Outdoor Air Quality (OAQ) based on gases present.

The ZMOD4510 includes non-selective measurement of nitrogen dioxide (NO2) and ozone (O3), as well as selective ozone measurement using ultra-low power.  It supports international standards for air quality (such as the US EPA), is excellent for low-voltage and low power battery applications (ultra-low power consumption down to 0.2 mW). Water and dustproof versions are available, and can be customized for mobile, industrial land consumer applications.

Target applications

• Air monitoring for nitrogen dioxide and ozone 
• Detect unhealthy conditions in outdoor air
• Personal air quality monitors
• Smart City instrumentation
• Automation based on AQI (HCAV systems, building air purification systems)
