The Celsius temperature sensor is a fast-response, high-accuracy temperature sensor. We have a sealed and protected version available here, but this unsealed board-level version is great for integrating directly into projects and for use 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.
The TSYS01 sensor itself has a fast time response and we designed the whole package to maintain that speed.
The electrical schematic and board layout are open-source and the design files are available below. Feel free to adapt for your own needs.
