DFRobot Gravity CT1780 K-Type Thermocouple Amplifier

DFRobot Gravity CT1780 K-Type Thermocouple Amplifier makes monitoring an extreme temperature range from -270°C to 1372°C straightforward and scalable. This thermocouple amplifier utilizes the 1-wire protocol, allowing multiple sensors to be daisy-chained on a single data line for monitoring various zones in different applications. The Gravity CT1780 K-type thermocouple amplifier features an integrated DIP switch, further simplifying the identification of individual sensors in a multi-point network, making complex setups manageable. This thermocouple amplifier features a Gravity single bus communication interface and is compatible with 3.3V/5V controllers. The Gravity CT1780 K-type thermocouple amplifier accurately digitizes signals from a K-type thermocouple, providing 0.25°C resolution. Typical applications include ceramic and pottery kilns, metal forging and smelting, DIY reflow oven, and scientific research.

The Gravity CT1780 K-type thermocouple amplifier design drastically simplifies system wiring, requiring only a single data line to connect multiple sensors to a host controller. This architecture is ideal for projects that demand temperature monitoring across several distributed points over a wide area, as it conserves microcontroller I/O pins and reduces wiring complexity.
