Si7021 digital temperature sensor provides a great level of accuracy in detecting temperature and humidity in surrounding environment, it Uses I2C for data transfer so it works with a wide range of microcontrollers.
Si7021 comes with a tiny white cover on the IC is known as a Polytetrafluorethylene (PTFE) Membrane Filter. It keeps moisture out but allows humidity and blocks contaminants keeping your sensor safe from water damage while still proving accurate sensor readings
