SHT40

/*
The SHT40 is a temperature and humidity sensor that communicates via the I2C interface. Here's an example code in Arduino that reads the temperature and humidity from the sensor:

Note: This code uses the SHT4x library for Arduino to communicate with the SHT40 temperature and humidity sensor. You'll need to install the library before running this code. Also, note that the I2C address of the sensor is fixed at 0x44, so you don't need to specify the address in the code. Finally, note that the sensor has a measurement range of -40 to 125°C for temperature and 0 to 100% for humidity, and provides readings with an accuracy of ±0.2°C for temperature and ±2%RH for humidity.
