Detailed Description

Middleware to implement the ZMOD4XXX sensor interface. This module implements the ZMOD4XXX Middleware Interface.

Overview

The following measurement modes are EOL.

This module provides an API for configuring and controlling the ZMOD4XXX sensor. Supported ZMOD4XXX sensors are below.

I2C communication with the ZMOD4XXX sensor is realized by connecting with the rm_comms_i2c module.

Features

The ZMOD4XXX sensor interface implementation has the following key features:

Usage Notes

ZMOD4410 datasheet is here.
The ZMOD4410 has five modes of operation.
The ZMOD4410 will respond to TVOC immediately upon start-up; however, a conditioning period of 48 hours followed by a sensor module restart in an ambient environment is recommended to improve stability and obtain maximum performance.
Best results are achieved with continuous operation because the module algorithm can learn about the environment over time.

Method Description
IAQ 1st Generation Continuous Measurement of UBA levels for IAQ and eCO2, provides continuous data
IAQ 1st Generation Low Power Measurement of UBA levels for IAQ and eCO2, fixed sampling interval of 6 seconds
IAQ 2nd Generation Using AI for improved ppm TVOC, IAQ and eCO2 functionality (recommended for new designs)
IAQ 2nd Generation Ultra Low Power Using AI for improved ppm TVOC, IAQ and eCO2 functionality. This method offers a much lower power consumption
Relative IAQ Lightweight algorithm reacts to air quality changes and outputs a relative IAQ
Relative IAQ Ultra Low Power Lightweight algorithm reacts to air quality changes and outputs a relative IAQ. This method offers a much lower power consumption
Public Building AQ Standard (PBAQ) For highly accurate and consistent sensor readings to fulfill public building standards.
Odor Control signal based on Air Quality Changes
Sulfur-based Odor Discrimination The odors in “sulfur” (sulfur based) and “acceptable” (organic based) and shows an intensity level of the smell

ZMOD4450 datasheet is here.
The ZMOD4450 has one modes of operation.
The response time for a gas stimulation is always within a few seconds, depending on the gas and its concentration. An active or direct airflow onto the sensor module is not necessary since diffusion of ambient gas does not limit the sensor module response time. The ZMOD4450 will respond to typical refrigeration gases immediate upon start-up; however, a conditioning period of 48 hours in a refrigeration environment is recommended to improve stability and get maximum performance, as the module algorithm is able to learn about the refrigeration environment over time.

Method Description
RAQ Control signal based on Refrigerator Air Quality Changes

ZMOD4510 datasheet is here.
The ZMOD4510 has two modes of operation.
The ZMOD4510 in OAQ 1st Gen operation will respond to typical outdoor gases after a warm-up time of 60 min, consisting of 20 min for stabilization and 40 min for baseline finding.
For OAQ 2nd Gen operation a response to ozone will be seen after a warmup time of 30 min.
For NO2 O3 operation a response to nitrogen_dioxide and ozone will be seen after a warmup time of 5 min.
In all operation modes a conditioning period of 48 hours followed by a sensor module restart in an ambient environment is recommended to improve stability and obtain maximum performance.

Method Description
OAQ 1st Generation Measurement of Air Quality
OAQ 2nd Generation Selective Ozone featuring Ultra-Low Power
NO2 O3 Selective nitrogen dioxide and ozone firmware

A library corresponding to each of these modes is required. By setting in RA Configuration, the library will be generated in the ra/fsp/lib/rm_zmod4xxx folder of your project.

If an RTOS is used, blocking and bus lock is available.

Notifications

The ZMOD4xxx sensor needs a reset before operation; please input a reset signal to the RES_N pin (active low).

Program flow for OAQ 2nd gen is changed in FSP v4.0.0. Please refer to the programming manual [R36US0004EU] and the application note[R01AN5899].
R01AN5899 : https://www.renesas.com/document/apn/zmod4xxx-sample-application
R36US0004EU : https://www.renesas.com/document/mat/zmod4510-programming-manual-read-me

Bus Initialization

The ZMOD4XXX interface expects a bus instance to be opened before opening any ZMOD4XXX device. The interface will handle switching between devices on the bus but will not open or close the bus instance. The user should open the bus with the appropriate I2C Master Interface open call.

Initialization

Initialize with RM_ZMOD4XXX_Open(). One channel of timer is required to measure the waiting time at initialization.

From measurement start to data acquisition

After normal completion, start the measurement with RM_ZMOD4XXX_MeasurementStart(). An endless loop continuously checks the status of the ZMOD4XXX sensor and reads its data. The raw data is subsequently processed, and the air quality values are calculated.

If IRQ is enabled

  1. Call RM_ZMOD4XXX_MeasurementStart().
  2. Wait until RM_ZMOD4XXX_EVENT_MEASUREMENT_COMPLETE is received via IRQ callback.
  3. Call RM_ZMOD4XXX_Read(). This function will read the ADC data.
  4. Wait until RM_ZMOD4XXX_EVENT_SUCCESS is received.
  5. Call the DataCalculate API according to the mode.

If IRQ is disabled

  1. Call RM_ZMOD4XXX_MeasurementStart().
  2. Wait until RM_ZMOD4XXX_EVENT_SUCCESS is received.
  3. Call RM_ZMOD4XXX_StatusCheck(). This function will execute a status check over I2C.
  4. If RM_ZMOD4XXX_EVENT_MEASUREMENT_NOT_COMPLETE is received in callback, user should wait some time and then call RM_ZMOD4XXX_StatusCheck() again.
  5. Wait until RM_ZMOD4XXX_EVENT_MEASUREMENT_COMPLETE is received.
  6. Call RM_ZMOD4XXX_Read() and read the ADC data.
  7. Wait until RM_ZMOD4XXX_EVENT_SUCCESS is received.
  8. Call the DataCalculate API according to the mode.

Checking device error for IAQ 2nd Gen.

  1. Call RM_ZMOD4XXX_DeviceErrorCheck(). This function will execute a device error check over I2C.
  2. If any device error occurs, RM_ZMOD4XXX_EVENT_DEV_ERR_POWER_ON_RESET or RM_ZMOD4XXX_EVENT_DEV_ERR_ACCESS_CONFLICT are received in callback. If no device error, RM_ZMOD4XXX_EVENT_SUCCESS is received in callback.
