  • Peak Reflow Temperature (Cel)

    Peak Reflow Temperature (Cel) is a parameter that specifies the maximum temperature at which an electronic component can be exposed during the reflow soldering process. Reflow soldering is a common method used to attach electronic components to a circuit board. The Peak Reflow Temperature is crucial because it ensures that the component is not damaged or degraded during the soldering process. Exceeding the specified Peak Reflow Temperature can lead to issues such as component failure, reduced performance, or even permanent damage to the component. It is important for manufacturers and assemblers to adhere to the recommended Peak Reflow Temperature to ensure the reliability and functionality of the electronic components.

  • Supply Voltage-Max (Vsup)

    The parameter "Supply Voltage-Max (Vsup)" in electronic components refers to the maximum voltage that can be safely applied to the component without causing damage. It is an important specification to consider when designing or using electronic circuits to ensure the component operates within its safe operating limits. Exceeding the maximum supply voltage can lead to overheating, component failure, or even permanent damage. It is crucial to adhere to the specified maximum supply voltage to ensure the reliable and safe operation of the electronic component.

    3.3V
  • Temperature Grade

    Temperature grades represent a tire's resistance to heat and its ability to dissipate heat when tested under controlled laboratory test conditions.

    COMMERCIAL
  • Supply Voltage-Min (Vsup)

    The parameter "Supply Voltage-Min (Vsup)" in electronic components refers to the minimum voltage level required for the component to operate within its specified performance range. This parameter indicates the lowest voltage that can be safely applied to the component without risking damage or malfunction. It is crucial to ensure that the supply voltage provided to the component meets or exceeds this minimum value to ensure proper functionality and reliability. Failure to adhere to the specified minimum supply voltage may result in erratic behavior, reduced performance, or even permanent damage to the component.

    1.8V
  • Analog IC - Other Type

    Analog IC - Other Type is a parameter used to categorize electronic components that are integrated circuits (ICs) designed for analog signal processing but do not fall into more specific subcategories such as amplifiers, comparators, or voltage regulators. These ICs may include specialized analog functions such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), voltage references, or signal conditioning circuits. They are typically used in various applications where precise analog signal processing is required, such as in audio equipment, instrumentation, communication systems, and industrial control systems. Manufacturers provide detailed specifications for these components to help engineers select the most suitable IC for their specific design requirements.

  • Height Seated (Max)

    Height Seated (Max) is a parameter in electronic components that refers to the maximum allowable height of the component when it is properly seated or installed on a circuit board or within an enclosure. This specification is crucial for ensuring proper fit and alignment within the overall system design. Exceeding the maximum seated height can lead to mechanical interference, electrical shorts, or other issues that may impact the performance and reliability of the electronic device. Manufacturers provide this information to help designers and engineers select components that will fit within the designated space and function correctly in the intended application.

How to use CCS811

Although it can be used with other microcontrollers, we are explaining the connections of this module with Arduino to understand its working. If you are using this sensor for the first time after purchasing it, run the sensor for 48 hours to achieve a stable operation. During the first 48 hours, the change in resistance is higher due to its sensitivity changes. After that run it 20 minutes in any desired mode before using it.


Where to use CCS811

It is an ultra-low-power, highly compact and economical digital sensor module which is compatible with Arduino and CircuitPython. You can use this sensor for monitoring indoor air quality. It can be used with CircuitPython board, computer, Arduino or any other microcontroller that requires 5V DC supply for operation. Due to its extended battery life, you can use it in portable devices like smartwatches, etc.


CCS811 Modes of Operation

The CCS811 has 5 modes of operation as follows

• Mode 0: Idle, low current mode

• Mode 1: Constant power mode, IAQ measurement every second

• Mode 2: Pulse heating mode IAQ measurement every 10 seconds

• Mode 3: Low power pulse heating mode IAQ measurement every 60 seconds

• Mode 4: Constant power mode, sensor measurement every 250ms


In Modes 1, 2, 3, the equivalent CO2 concentration (ppm) and TVOC concentration (ppb) is calculated for every sample.

• Mode 1 reacts fastest to gas presence, but has a higher operating current

• Mode 3 reacts more slowly to gas presence but has the lowest average operating current.
