BlueRobotics Celsius Fast-Response, ±0.1°C Temperature Sensor (PCB) Offers a fast-response, high-accuracy temperature sensor Great for integrating directly into projects Includes four solder pads for ground Operates on 3.3 V Peak Current: 1.4 mA The BlueRobotics Celsius Fast-Response, ±0.1°C Temperature Sensor (PCB) is a fast-response, high-accuracy temperature sensor. The sensor is the Measurement Specialties TSYS01, which is accurate to ±0.1°C and communicates over I2C. It operates on 3.3 V I2C voltage but can accept power input up to 5.5 V. It includes four solder pads for ground, 3.3-5.5 V power, and 3.3 V I2C lines. The TSYS01 sensor itself has a fast time response and has been designed as the whole package to maintain that speed. The electrical schematic and board layout are open-source and the design files are available in the Technical Details tab. Feel free to adapt to your own needs.
