Frequently Asked Questions

What is the operating voltage range for the SHT20 probe?

The SHT20 sensor core operates from 2.1V to 3.6V. The I2C communication lines are also limited to this voltage range. For use with 5V logic systems like Arduino Uno, a logic level converter is required on the SDA and SCL lines to prevent damage to the sensor.

How do I connect and read data from the SHT20 using I2C?

Connect the probe's cable wires to your microcontroller: VDD (2.1-3.6V), GND, SDA (data), and SCL (clock). The SHT20 uses a standard I2C protocol. You can use the official Sensirion SHT2x library for Arduino or similar platforms to send measurement commands and read the temperature and humidity data registers.

Is the SHT20 probe suitable for outdoor or wet environments?

While the stainless steel probe offers good corrosion resistance, the SHT20 itself is not rated with a specific IP (Ingress Protection) code for waterproofing. The sensor is sensitive to condensation. For outdoor or wet environments, it should be installed in a protective, ventilated enclosure that shields the electronics from direct water exposure while allowing air circulation.
