Questions about this product

What's the main difference between the SHT20, SHT30, and SHT40 versions?
The primary difference between the models is their measurement accuracy and resolution. The SHT40 is the newest and most accurate, the SHT30 is a popular mid-range option, and the SHT20 is a reliable, more economical choice. All three measure both temperature and humidity.
How do I connect this probe to an Arduino or Raspberry Pi?
This sensor uses the I2C communication protocol, which is standard on most microcontrollers. You just need to connect four wires: power (VCC), ground (GND), serial data (SDA), and serial clock (SCL) to the corresponding pins on your board.
Is the whole 1-metre assembly completely waterproof?
The stainless steel probe head and the 1-metre cable are waterproof, meaning you can safely submerge that part of the sensor. However, the electronics at the other end of the cable where you make your connections are not waterproof and must be kept dry.
