SEN0385 SHT3x Temperature and Humidity Sensor Probe
Overview
The SEN0385 is an industrial-grade temperature and humidity sensor probe built around a Sensirion SHT3x-series IC. It features a waterproof and breathable protective housing that allows it to operate in high-humidity or outdoor environments while maintaining a digital I2C interface. The probe is designed for 3.3V to 5V systems and provides high-accuracy readings with a wide operating temperature range of -40 to 125 degrees Celsius.
Why Choose This Part
The sensor offers an excellent balance of accuracy with plus or minus 2 percent RH and a fast 8-second response time. Its wide supply voltage range of 2.4V to 5.5V ensures compatibility with both low-power ARM microcontrollers and 5V Arduino platforms without additional level shifting. The integrated probe housing eliminates the need for custom enclosure design in outdoor or industrial applications.
Applications
Key Specifications
Getting Started
Connect the probe via its 4-wire interface to any I2C master device, ensuring the VDD is within the 3.3V to 5V range for best performance with most dev boards. Use standard SHT3x libraries available for Arduino or ESP32 to read the 16-bit digital output. Ensure the I2C pull-up resistors are appropriately sized if using long cable runs to maintain signal integrity.
