Ocean: STS35 Temperature Sensor for Arduino and Raspberry Pi

The CQRSTS35A high-precision digital temperature sensor launched by CQRobot has a built-in STS35 sensor chip newly launched by Swiss Sensirion Company on the motherboard. It provides a fully calibrated, linear and supply voltage compensated digital output with an ultra-high measurement accuracy of plus or minus 0.1 degrees Celsius.

The sensor has a wide measurement range of minus 40 degrees Celsius to 125 degrees Celsius, and has the function of automatic heating and dehumidification to keep the chip dry, which means that it can work in a certain humidity environment. At the same time, the I2C communication speed of the sensor can be up to 1MHz.
