The SI7021 Temperature and Humidity sensor module is low-cost, easy to use, and highly accurate. All you need is two lines for I2C communication, and you’ll have relative humidity readings and accurate temperature readings as well! This sensor is ideal for environmental sensing and data logging, perfect for a weather station or humidor control system.

The SI7021 temperature and humidity sensor also comes equipped with a hydrophobic PTFE filter covering the inlet on the sensor. This filter blocks contaminants but allows water vapor to pass through, keeping your sensor safe from water damage while still proving accurate sensor readings.
