Arduino® MKR Therm Shield 擴展板（ASX00012）義大利原廠，可接Ｋ型熱電偶
The MKR THERM Shield allows a MKR board to acquire temperatures from a thermocouple of type K and a DS18Bxxdigital one wire sensor Thermocouples are based on the thermoelectric properties of a junction between two different metals and are capable of measuring with good precision ranges from -270 to +1372 Celsius (K type) that are far beyond any digital sensors or NTC/PTC (thermistor) range.
A typical application of thermocouples is in boilers, soldering stations and coolers. Also good quality 3D printers rely on thermocouples to measure the extruder temperature. The K thermocouple has usually two wires, made of Alumel and Chromel that need to be connected with special care: no solder, just mechanical connection, therefore we support on the shield both the standard K type connector and a screw terminal.
Features
- • The analogue nature requires specific interfacing and this shield relies on the MAX31855 thermocouple digital interface
- • Max. operating temperature range: -200°C to +700°C
- • Operating voltage: 3.3V
The MKR THERM Shield allows a board of the MKR family to acquire temperatures from a thermocouple of type K and a DS18Bxx digital one wire sensor. The Thermocouple is a kind of temperature sensor that offers high accuracy and a wide range of measured temperatures. Its analogue nature requires specific interfacing and this shield relies on the MAX31855 thermocouple digital interface. The two connectors of the MKR THERM Shield allow the usage of Type K thermocouples with or without a plug attached to the metal wires. The MKR THERM Shield has its own library to read the temperature measured by the thermocouple.
