Celsius Fast-Response, ±0.1°C Temperature Sensor (PCB)
This board-level version of the Celsius Temperature Sensor can be tightly integrated into projects or used in dry environments.
The sensor is the Measurement Specialties TSYS01, which is accurate to ±0.1°C and communicates over I2C. It operates on 3.3V I2C voltage but can accept power input up to 5.5V. It includes four solder pads for ground, 3.3V-5.5V power, and 3.3V I2C lines.
