CY8CKIT-025 PSoC® 精密模拟温度传感器扩展板套件(EBK)

The CY8CKIT-025 PSoC® Precision Analog Temperature Sensor Expansion Board Kit (EBK) includes 5 temperature sensors and examples projects to make temperature sensing and control design quick and easy. This kit enables the designer to measure temperature accurately to a resolution of 0.1℃.

The CY8CKIT-025 EBK is designed for use with the CY8CKIT-030 PSoC 3 Development Kit and the CY8CKIT-001 PSoC Development Kit (all sold separately). Combining CY8CKIT-025 EBK with a development kit provides a complete single chip temperature sensing and control solution.

CY8CKIT-025 EBK包括:

PT100 Class B Resistive Temperature Detector (RTD)

Type K Thermocouple

NTC Thermistor

2 Temperature Diodes (2N3904 transistors)

DS600 IC temperature sensor

Examples projects for temperature sensing measurement, combined temperature and voltage measurement and fan control

Includes a bonus CY8CKIT-012 PSoC Prototyping and Development Expansion Board
