    MCP9808 - Digital Temperature Sensor

    Microchip Technology Inc.’s MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.25°C/±0.5°C (typical/maximum) accuracy

    Documentation

    • You can find the datasheet here

    Usage

    Important: make sure you properly setup the I2C pins especially for ESP32 before creating the I2cDevice, make sure you install the nanoFramework.Hardware.ESP32 nuget:

    //////////////////////////////////////////////////////////////////////
    // when connecting to an ESP32 device, need to configure the I2C GPIOs
    // used for the bus
    Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
    Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);
    

    For other devices like STM32, please make sure you're using the preset pins for the I2C bus you want to use.

    Hardware Required

    • MCP9808
    • Male/Female Jumper Wires

    Circuit

    • SCL - SCL
    • SDA - SDA
    • VCC - 5V
    • GND - GND

    Code

    I2cConnectionSettings settings = new I2cConnectionSettings(1, Mcp9808.DefaultI2cAddress);
    I2cDevice device = I2cDevice.Create(settings);
    
    using(Mcp9808 sensor = new Mcp9808(device))
    {
        while (true)
        {
            Debug.WriteLine($"Temperature: {sensor.Temperature.Celsius} ℃");
            Debug.WriteLine();
    
            Thread.Sleep(1000);
        }
    }
