Sensors are devices that convert physical stimuli into electrical signals for direct use, or for further processing and evaluation with electronic circuits. An evaluation board is a printed circuit board which holds a microcontroller or related components, and often different types of connectors, dip switches, LEDs, and buttons for testing a device. In this article, we will look at the SI7022-23-IVB evaluation board and its applications in the field of sensors, as well as its working principle.

SI7022-23-EVB is an evaluation board that comes with a digital temperature sensor of the same name. It is designed to be used with a wide range of applications, such as home automation, automotive, and industrial. The board has a built-in 2.4 GHz radio to provide wireless communication. The sensor has a sensing range of -20°C to 125°C, and its onboard MCU provides various features such as local and remote interrupt detection, programmable temperature resolution, and low power mode.

The SI7022-23-EVB evaluation board offers a wealth of features, including an 8-bit UART interface, SPI and I2C communication and support for various host interface types. The MCU also provides on-board temperature calibration and data logging capabilities, making it ideal for applications such as environmental monitoring. It also offers a wide range of output port options, including 3x3, 4x4, and 6x6 channels for motor control, lighting, and other industrial environment monitoring.

The working principle of the SI7022-23-EVB is simple. It operates at a supply voltage of 2.7 - 5.5V and has a power consumption of around 26uA at 25C. The board contains a built-in amplifier and a temperature sensor, which is connected to the ADC inside the MCU.
