Working Principle of SI7005USB-DONGLE

The Si7005USB-DONGLE is based on the Si7005 Digital Humidity/Temperature Sensor from Silicon Laboratories. The Si7005 is a highly integrated digital humidity and temperature sensor with an SPI or I2C interface. The integrated sensor includes an electro-mechanical sensing element and an analog to digital converter that can measure relative humidity from 0-100%RH with an accuracy of ±3%RH. The Si7005USB-DONGLE utilizes the Si7005’s I2C interface to communicate with the I2C bus of the board on which it is mounted.

The Si7005 also includes an integrated temperature sensor which can measure temperatures from -25°C to +85°C with an accuracy of ±2°C. The Si7005USB-DONGLE utilizes the Si7005’s temperature sensor to measure the temperature of the environment in which it is placed. All data collected from the Si7005 sensor is transmitted to a USB interface via the I2C bus.

The USB interface of the Si7005USB-DONGLE allows the user to view the measurement data on a computer or laptop. The Si7005USB-DONGLE also includes a 3.3V regulator and onboard LEDs to easily identify the board is powered on and functioning correctly. The Si7005USB-DONGLE also includes an onboard push-button that can be used to trigger a measurement cycle, view the temperature and humidity data, or reset the board.

Conclusion

The Si7005USB-DONGLE is a convenient and low-cost evaluation board that is perfect for a wide range of application scenarios. It provides an easy way to measure the temperature and humidity in different environments and can even be used to control and monitor environmental conditions. The Si7005USB-DONGLE makes it easy to connect to a variety of microcontrollers and host processors, and the USB interface allows for easy access to the measured values. The Si7005USB-DONGLE is an invaluable tool for anyone looking to quickly and easily prototype and develop applications that require temperature and humidity measurements.
