Its multi-sensing capability makes it a versatile component for projects where multiple environmental parameters need to be measured simultaneously.
How to Choose
When selecting a humidity sensor, consider the voltage compatibility, which for this product is 3.3 V. The interface type, IIC or I2C, is also crucial for integration with your chosen micro-controller. Ensure the sensor type, in this case temperature, humidity, and barometric pressure, meets your project's requirements. If you have concerns about how to calibrate humidity sensor readings, consult your micro-controller's documentation for specific programming instructions. A faulty sensor may provide inconsistent readings or no data at all.
Grit / Spec Guide
This humidity sensor operates at 3.3 V and communicates via an IIC, I2C interface. It is constructed from PCB material. The module integrates a Hall Sensor for its sensing theory, providing data for temperature, humidity, and barometric pressure. When connecting, ensure correct polarity to prevent damage to the working sensor. Check your micro-controller's data sheet for compatible I2C pull-up resistor values if you encounter communication issues.
Care & Safety
Handle the humidity sensor breakout board with care to avoid damage to the PCB material and sensitive components. Always ensure the power supply is 3.3 V to prevent overvoltage. When connecting, double-check the interface pins for IIC or I2C to avoid short circuits. Keep the sensor free from dust and moisture, as these can affect the accuracy of the temperature, humidity, and barometric pressure readings. Do not attempt to physically calibrate humidity sensor components; all calibration should be done via software.
