  10. M5Stack NCIR Unit MLX90614 Contactless Temperature Sensor Module -70C~382.2C GROVE I2C Development Board

    M5Stack NCIR Unit MLX90614 Contactless Temperature Sensor Module -70C~382.2C GROVE I2C Development Board

    Description:
     
    NCIR featured with built-in infrared sensor MLX90614. It can be used to measure the surface temperature of a human body or other object.
    Unlike most temperature sensors, this sensor measures infrared light bouncing off of remote objects so it can sense temperature without having to touch them physically. Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted. Because it doesn’t have to touch the object it’s measuring, it can sense a wider range of temperatures than most digital sensors! It takes the measurement over an 90-degree field of view so it can be handy for determining the average temperature of an area.
    The MLX90614 is factory calibrated in wide temperature ranges: -40 to 125 ˚C for the ambient temperature and -70 to 382.2 ˚C for the object temperature. T
    Connect with M5Core via GROVE A IIC(0x5A).
     
    Product Features:

    • Operating voltage: 4.5 to 5.5V
    • Measuring object temperature range: -70°C ~ 382.2°C
    • Measuring ambient temperature range: -40 to 125 ˚C
    • Measurement accuracy at room temperature: ±0.5°C
    • Field of view: 90°
    • Sofrware Development Platform: for Arduino, UIFlow(Blockly, Python)
    • Two Le go-compatible holes

    Applications:

    • Body Temperature Measurement
    • Object (biological) Move Detection

  13. ADC CMOS CD74HC4067 16CH Channel Analog Digital Multiplexer Module Board Sensor Controller For Arduino

    ADC CMOS CD74HC4067 16CH Channel Analog Digital Multiplexer Module Board Sensor Controller For Arduino

    Description:
     
    1. This is a break out board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can't be higher than VCC), and the connections function in either direction. To control it, connect 4 digital outputs to the chip's address select pins (S0-S3), and send it the binary address of the channel you want (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins!
    2. Since the mux/demux also works with digital signals, you can use it to pipe TTL-level serial data to or from multiple devices. For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller. You can then select any one of those 16 devices to listen to. If you want two-way communications, you can add a second board to route your microcontroller's TX line to 16 device's RX lines. By using multiple boards, you can create similar arrangements for I2C, SPI, etc.
    3. The internal switches are bidirectional, support voltages between ground and VCC, have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching. The board also breaks out the chip's “enable” pin, which when driven high, will completely disconnect the common pin (all switches “off”).
     
    Features:
     
    2V to 6V operation
    “On” resistance: 70 Ohms @ 4.5V
    6ns break-before-make @ 4.5V
    Wide operating temperature range: -55C to 125C
    Function: gathering all the way ADC 16 analog signals.
