Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The Adafruit MCP9600 does all that for you, and can be easily interfaced with any microcontroller or single-board-computer with I2C. Inside, the chip handles all the analog stuff for you, and can interface with just about any thermocouple type: K, J, T, N, S, E, B and R type are all supported! You can also set various alerts for over/under temperature, and read the thermocouple (hot) temperature and the chip (cold) temperature. All this over common I2C This breakout board has the chip itself, a 3.3V regulator and level shifting circuitry, all assembled and tested. Works great with 3.3V or 5V logic. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard). Match it up with our 1m K-type thermocouple. Works with any K, J, T, N, S, E, B and R type thermocouple Datasheet rated for: K Type: -200°C to +1372°C J Type: -150°C to +1200°C T Type: -200°C to +400°C N Type: -150°C to +1300°C E Type: -200°C to +1000°C S Type: +250°C to +1664°C B Type: +1000°C to +1800°C R Type: +250°C to +1664°C Resolution of ±0.0625 °C - note that K thermocouples have about ±2°C to ±6°C accuracy Internal temperature reading 3.3 to 5v power supply and logic level compliant I2C data connection. | ![]() B08V4X5L5B Price: $16.59 Score: 6.849 Category: Electronics Rating: 4.3 Votes: 17 Find similar productsACEIRMC 6pcs INA219 I2C Bi-Directional DC Current Power Supply Sensor Breakout Module Compatible with Arduino Raspberry Pi. . |

This is a pre-wired and waterproofed (with heat shrink) version of a 1 Wire DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances! 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. | ![]() B01I92B5W2 Price: $8.99 Score: 6.410 Category: Electronics Rating: 4 Votes: 1 Find similar productsTOLAKO GPIO Module with Dual Channel Digital I/O Ports for Arduino.
