How Does The CO2 3 Click Board™ Work?
The CO2 3 Click Board™ is based on the XENSIV™ PASCO2V01BUMA1, the smallest CO2 sensor module from Infineon Technologies that uses photoacoustic spectroscopy technology to measure indoor air quality. The module consists of a gas measuring cell with an infrared (IR) emitter, a high-SNR microphone as the acoustic detector, and an XMC™ microcontroller for data processing, delivering exceptional accuracy, boasting a rate of ±30ppm ±3% of reading. Its diffuser port allows for efficient gas exchange while maintaining dust protection, and its acoustic isolation ensures highly accurate CO2 sensing information. Because of its superior features, this board makes an excellent choice for building automation, smart home appliances, and air quality monitoring, including air purifiers, thermostats, and HVAC systems. Its precise measurements can help optimize indoor air quality, improving human health, productivity, and comfort.
As mentioned, the PASCO2V01BUMA1 overcomes the size, performance, and assembly challenges of existing CO2 sensor solutions by using photoacoustic spectroscopy (PAS). It uses pulses of light from an infrared source that pass through an optical filter explicitly tuned to the CO2 absorption wavelength. The CO2 molecules inside the measurement chamber absorb the filtered light, causing the molecules to shake and generate a pressure wave with each pulse, known as the photoacoustic effect. The sound is then detected by an acoustic detector optimized for low-frequency operation, and the microcontroller converts the output into a CO2 concentration reading. This results in a highly accurate and reliable measurement of CO2 levels in real time.
All significant components of the XENSIV™ PASCO2V01BUMA1 CO2 module are developed in-house according to Infineon's high-quality standards, ensuring the highest quality and performance. The dedicated MCU runs advanced compensation algorithms to deliver direct and reliable ppm readouts of actual CO2 levels. The available configuration options, such as ABOC, pressure compensation, signal alarm, sample rate, and early measurement notification, make this board one of the most versatile plug-and-play CO2 solutions on the market.
This Click board™ comes with a configurable host interface that allows communication with MCU using the selected interface. The PASCO2V01BUMA1 can communicate with MCU using the UART interface with commonly used UART RX and TX pins as its default communication protocol operating at 115200bps to transmit and exchange data with the host MCU or using the optional I2C interface. The I2C interface is compatible with the Fast-Mode allowing a maximum frequency of 400kHz. Selection is made by positioning SMD jumpers marked COMM SEL to the appropriate position. All jumpers must be on the same side, or the Click board™ may become unresponsive.
As a third option for communication with the MCU, users have a PWM interface controlled via the PWS pin of the mikroBUS™ socket. The PWS pin is first asserted after the Power-On boot sequence (not after soft reset), and the level of the pin is checked. If a low level is detected, an internal interrupt routine configures the device into Continuous mode and starts a measurement sequence. At the end of each measurement sequence, the level of this pin is polled. If it is high, the device is configured back to Idle mode. The PWO pin, routed to the AN pin of the mikroBUS™ socket by default, offers the possibility to read out the CO2 concentration by delivering a PWM signal whose timing information contains the CO2 concentration value. At the end of each measurement sequence, the device updates the PWM timing with the measured CO2 concentration. This board also possesses an additional interrupt alert signal, routed on the INT pin of the mikroBUS™ socket, to provide a notification of CO2 measurements that violate programmed thresholds.
The CO2 3 Click Board™ can only be operated with a 3.3V logic voltage level. Since the sensor module for proper operation requires a voltage level of 12V, this Click board™ also features the TLV61046A, a voltage boost converter to generate a stable 12V supply. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
