    DS18B20 TEMPERATURE SENSOR MODULE

    0 out of 5

    DS18B20 TEMPERATURE SENSOR MODULE

    The sensor can be powered with a 3.0V-5.5V power supply, so a 5V rail from a standard Arduino board will work just fine for that.
    ⦁ It can measure temperatures from -55C (-67F) to +125C (257F), which is perfect for general usage at home.
    ⦁ +- 0.5C accuracy, temperatures can be measured in 0.5C, 0.25C, 0.125C or 0.0625C increments.
    ⦁ Multiple such sensors can be connected do a single (!) data line, meaning we could control more than one sensor with just a single wire.
    ⦁ Supports upper and lower temperature alerts

    DS18B20 TEMPERATURE SENSOR PROBE WATERPROOF

    DS18B20 TEMPERATURE SENSOR PROBE WATERPROOF

    This is a 1 Meter Long Waterproof digital temperature sensor probe based on DS18B20 sensor. It is very handy for when you need to measure something far away, or in wet conditions. Because they are digital, you don’t get any signal degradation even over long distance.
    ⦁ These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.
    ⦁ The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication. When using with microcontroller put a 4.7k resistor to sensing pin, which is required as a pullup from the DATA to VCC line.

    LM35

    The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in˚ Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigradescaling.

    MAX6675 MODULE WITH K TYPE THERMOCOUPLE SENSOR

    0 out of 5

    MAX6675 MODULE WITH K TYPE THERMOCOUPLE SENSOR

    The MAX6675 performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI™-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1024°C, and exhibits thermocouple accuracy of 8LSBs for temperatures ranging from 0°C to +700°C.
