{"title":"Gravity: I2C High Temperature Sensor (K-Type, 800℃)","handle":"gravity-i2c-high-temperature-sensor-k-type-800","url":"/products/gravity-i2c-high-temperature-sensor-k-type-800","description":"This Gravity I2C high-temperature sensor pairs a signal amplification module (MAX31855K) with a stainless steel sheathed K-type thermocouple probe for measuring temperatures up to 800 °C. The module converts the thermocouple's millivolt signal to a 14-bit digital reading over I²C, with cold-junction compensation built in.\n\nThe Gravity I²C interface makes wiring simple — just connect power, ground, SDA, and SCL to any 3.3 V or 5 V microcontroller. The module supports the full K-type range of −270 to 1,372 °C (with a compatible probe), and the included probe is rated to 800 °C.\n\nKey Features\n\n\nMAX31855K Chip – 14-bit, 0.25 °C resolution digital temperature measurement\n\nWide Temperature Range – Module supports −270 to 1,372 °C; included probe rated to 800 °C\n\nGravity I²C Interface – Simple connection to Arduino, Raspberry Pi, and other controllers\n\n3.3 V / 5 V Compatible – Works with a wide range of boards\n\nSwappable Probe – Compatible with any standard K-type thermocouple\n\n\nSpecifications\n\nSignal Amplification Module:\n\n\nInput Voltage: 3.3–5.5 V\n\nTemperature Range: −270 to 1,372 °C\n\nResolution: 0.25 °C\n\nAccuracy: ±2 °C (−200 to 700 °C), ±4 °C (700 to 1,350 °C)\n\nInterface: Gravity I²C (logic level 0–3.3 V)\n\nDimensions: 44 × 22 mm\n\n\nK-Type Thermocouple Probe (included):\n\n\nTemperature Range: Up to 800 °C\n\nAccuracy: ±2.5 °C\n\nProbe Length: 50 mm\n\nProbe Diameter: 4 mm\n\nWire Length: 1.5 m\n\nProperties: Waterproof, corrosion-resistant, high-temperature resistant\n\n\nIdeal For\n\nElectric ovens and furnaces\nPottery kilns\nGas flame temperature measurement\nIndustrial and scientific high-temperature monitoring\n\n\nResources\n\nProduct Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":5569,"title":"Default Title","sku":"DF-DFR0558","price":43.95,"on_sale":false,"in_stock":true,"available_quantity":68,"option1":"Default Title"}]}
