Notes: Works with any K type thermocouple. K thermocouples have about ±2℃ to ±6℃ accuracy. Internal temperature reading. 3 to 5v power supply and logic level compliant. SPI data output requires any 3 digital I/O pins. Description: This temperature module is capable of finishing all missions and connecting any microcontroller even with no analog input. Built-in SPI interface creates a super high speed transmission to achieve real-time temperature measurement. Furthermore, the temperature sensor module directly outputs digital temperature with no need for amplifier or ADC. Features: This temperature module does everything for you, and can be easily interfaced with any microcontroller, even with no analog input. This breakout board comes with a chip, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, which have been assembled and tested. Thermocouples are very sensitive, which requires a good amplifier with a cold-junction compensation reference. Comes with a 2pin terminal block( for connecting to the thermocouple) and pin header( to plug into any breadboard). Built-in SPI interface offers a high speed transmission. The temperature sensor module outputs digital temperature directly with no amplifier or ADC required. Specifications: Product type: Temperature Sensor Module Temperature measurement range: -200℃ to 1350℃ Input voltage: DC 3-5V Resolution: 14-digit Temperature accuracy: 0.25℃ Suitable: For K Type Thermocouple Breakout Board Package size: approx. 5 * 5 * 5 cm/ 1.97 * 1.97 * 1.97 in Package weight: 4.4g Package List: 1 * Temperature Sensor Module 1、This temperature module does everything for you, and can be easily interfaced with any microcontroller, even with no analog input. 2、This breakout board comes with a chip, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, which have been assembled and tested. 3、Thermocouples are very sensitive, which requires a good amplifier with a cold-junction compensation reference. 4、Comes with a 2pin terminal block( for connecting to the thermocouple) and pin header( to plug into any breadboard). 5、Built-in SPI interface offers a high speed transmission.
