It digitises the tiny thermocouple signal and provides temperature readings with 0.25℃ resolution over a very wide measurement range.Instead of using a separate data line for every probe, the module communicates over a Gravity Single Bus 1-Wire style interface. Multiple CT1780 units can be daisy-chained on a single data line, which is handy for multi-zone temperature monitoring in ovens, kilns, furnaces, BBQ smokers and lab setups.An onboard DIP switch helps identify individual sensors in a multi-point network, working alongside the unique 64-bit address used by the 1-Wire protocol. The package includes the CT1780 amplifier board, a K Type thermocouple and a Gravity 3-pin cable.Features:Cold-junction compensation: Improves accuracy when measuring with a K-Type thermocouple.1-Wire communication: Uses a simple single data line for temperature data.Daisy-chain support: Multiple sensors can be connected on one data line.Onboard DIP switch: Allows a user-defined address for easier physical sensor identification.Unique 64-bit address: Uses the addressing capability inherent to the 1-Wire protocol.Extreme temperature range: Supports K-Type thermocouple measurements from -270℃ to +1372℃.High resolution: Provides 14-bit / 0.25℃ temperature measurement resolution.Specifications:Input Voltage: 3.3~5.5V DCThermocouple Type: K TypeMeasurement Range: -270℃~+1372℃Operating temperature range of the amplifier board: -40℃~+125℃Temperature measurement resolution: 14 bit/0.25℃Temperature measurement error: ≤±2℃（-200℃~700℃）, ±4℃（700℃~1350℃）Communication Interface: Gravity Single BusAmplifier board size: 44*22mmWell suited to DIY reflow ovens, ceramic and pottery kilns, metal forging and smelting, custom BBQ or smoker loggers, and scientific temperature measurement.","vendor":"DFRobot","in_stock":true,"options":[],"variants":[{"id":15646,"title":"Default Title","sku":"DF-SEN0656","mpn":"SEN0656","price":42.73,"on_sale":false,"in_stock":true,"available_quantity":587}]}
