The SI7034-EVB is an evaluation board for the SI7034 relative humidity and temperature sensor IC. It is useful for scientists and engineers when examining and testing the relative humidity and temperature relative to their given experiment or product development. The Si7034 Humidity and Temperature Sensor IC responds quickly, accurately and reliably to changes in relative humidity and temperature making it an ideal fit for application fields that rely heavily on these two factors such as climate control, meteorology, agriculture, health care, and environmental safety.

The device consists of a single chip that has both digital and analog components. It contains a temperature sensor, a humidity sensor, an analog-to-digital converter (ADC), a digital output module, and a calibration memory. The humidity sensing element is a thin-film capacitor composed of aluminum oxide and lithography-fabricated platinum electrodes. The temperature sensor is a thin-film thermistor with a thermistor coating that functions as the temperature sensing element. It uses a Wheatstone bridge circuit with an added resistor to measure the relative humidity levels.

To work correctly, certain signal strength thresholds must be reached. To make these measurements, the Si7034 measures voltage changes that occur at these thresholds. The analog-to-digital conversion is used to convert the voltage readings into digital signals. This allows the device to send accurate readings of humidity and temperature to the user. The calibration memory helps the device store all of the necessary calibration values.

Once the signal processing and analog-to-digital conversion is completed, the digital output module is used to output the readings to the user. The Si7034-EVB allows all of the readings and measures to be easily outputted to computers and software. The module is completed with a USB connector that allows the data to be easily accessed. It also comes with a graphical user interface (GUI).

In summation, the SI7034-EVB is an extremely useful evaluation board used by scientists and engineers. It allows for a variety of readings to be taken with regards to humidity and temperature. This makes it an ideal fit for industries where climate control, meteorology, agriculture, health care, and/or environmental safety are of the utmost importance. The device can measure humidity and temperature quickly, accurately, and reliably which makes it a valuable asset when working in these industries.
