    The Maximum Operating Temperature is the maximum body temperature at which the thermistor is designed to operate for extended periods of time with acceptable stability of its electrical characteristics.

    85°C
  • Min Operating Temperature

    The "Min Operating Temperature" parameter in electronic components refers to the lowest temperature at which the component is designed to operate effectively and reliably. This parameter is crucial for ensuring the proper functioning and longevity of the component, as operating below this temperature may lead to performance issues or even damage. Manufacturers specify the minimum operating temperature to provide guidance to users on the environmental conditions in which the component can safely operate. It is important to adhere to this parameter to prevent malfunctions and ensure the overall reliability of the electronic system.

    -40°C
  • Output Type

    The "Output Type" parameter in electronic components refers to the type of signal or data that is produced by the component as an output. This parameter specifies the nature of the output signal, such as analog or digital, and can also include details about the voltage levels, current levels, frequency, and other characteristics of the output signal. Understanding the output type of a component is crucial for ensuring compatibility with other components in a circuit or system, as well as for determining how the output signal can be utilized or processed further. In summary, the output type parameter provides essential information about the nature of the signal that is generated by the electronic component as its output.

  • Max Supply Voltage

    In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

  • Sensor Type

    In electronic components, the parameter "Sensor Type" refers to the specific type of sensor technology used in a particular component to detect and measure physical phenomena such as light, temperature, pressure, motion, or proximity. Different sensor types utilize various principles and mechanisms to convert the detected input into an electrical signal that can be processed by the electronic component. Common sensor types include photodiodes, thermistors, accelerometers, and proximity sensors, each designed for specific applications and environments. Understanding the sensor type is crucial for selecting the right component for a given task and ensuring accurate and reliable sensing capabilities in electronic systems.

  • REACH SVHC

    The parameter "REACH SVHC" in electronic components refers to the compliance with the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation regarding Substances of Very High Concern (SVHC). SVHCs are substances that may have serious effects on human health or the environment, and their use is regulated under REACH to ensure their safe handling and minimize their impact.Manufacturers of electronic components need to declare if their products contain any SVHCs above a certain threshold concentration and provide information on the safe use of these substances. This information allows customers to make informed decisions about the potential risks associated with using the components and take appropriate measures to mitigate any hazards.Ensuring compliance with REACH SVHC requirements is essential for electronics manufacturers to meet regulatory standards, protect human health and the environment, and maintain transparency in their supply chain. It also demonstrates a commitment to sustainability and responsible manufacturing practices in the electronics industry.

This is the modified circuit diagram. The max30100 pulse Oximeter sensor connection with the Arduino remains the same. This time I added a 16×2 LCD. As you can see, pin number 1 and pin number 16 are connected with the Arduino’s ground. Pin number 2 and pin number 15 are connected with the Arduino’s 5 volts. Pin number 3 is the contrast pin and is connected with the middle leg of the potentiometer this is used for the LCD contrast adjustment.

The RS pin of the LCD is connected with the Arduino’s pin number 9, the R/W pin is connected with the ground, Enable pin is connected with the Arduino’s pin number 8. Pins D4 to D7 of the 16X2 LCD is connected with the Arduino’s pins 7, 6, 5, and 4.

Frequently Asked Questions

1.How to connect the MAX30100 chip to the MCU?

You only need to connect to the I2C interface, if the microcontroller does not have an I2C interface, you can use IO to simulate an I2C.

2.What electronic component is MX30100?

MAX30100 is a sensor chip that can collect heart rate, blood oxygen temperature, and the communication serial port uses I2C.
MAX30100 is a sensor that can read heart rate and blood oxygen. The communication method is through IIC.
Its working principle is to get the ADC value of heart rate through infrared LED light.

3.Will the red LED light up when the MAX30100 is powered on?

It is not appropriate to use 12V voltage to directly bring 4 red LED lights. It is easy to cause damage to one or several of the four LED lights, so it will not light up.
Because the forward voltage drop of a general red LED light-emitting tube is only about 2.2V
