Frequently Asked Questions

What is the operating voltage range for the SHT35-DIS-B2.5KS sensor?

The SHT35-DIS-B2.5KS operates from a wide supply voltage range of 2.4V to 5.5V DC. This makes it directly compatible with both 3.3V and 5V microcontroller systems, such as Arduino, Raspberry Pi, and ESP32 boards, without requiring a level shifter.

How do I communicate with this sensor using the I2C interface?

The sensor uses a standard I2C communication protocol. You will need to connect the SDA (data) and SCL (clock) lines to your microcontroller, along with power and ground. The sensor's I2C address is configurable, and Sensirion provides comprehensive datasheets with command sets for initiating measurements and reading data.

Is the sensor calibrated, and what is its long-term stability?

Yes, the SHT35-DIS-B2.5KS is fully calibrated and delivers linearized digital output. Sensirion's CMOSens® technology ensures excellent long-term stability, meaning the sensor maintains its specified ±1.5% RH accuracy over its operational lifetime with minimal drift, which is critical for long-term monitoring applications.

Can this sensor withstand harsh or condensing environments?

The SHT35 is designed with robustness in mind and can operate across its full -40°C to +125°C range. It features a protective cover and is engineered to handle challenging conditions, including temporary exposure to condensation. For prolonged exposure to liquids, additional conformal coating on your PCB may be recommended.
