Product details

Overview

SI7013USB-DONGLE from Silicon Labs is a USB-based evaluation and development dongle for the SI7013 relative humidity and temperature sensor IC, featuring integrated USB-to-I²C bridge, on-board SI7013 in 3×3 mm DFN package, factory-calibrated accuracy of ±1.5% RH and ±0.2°C, and plug-and-play operation with Simplicity Studio software. It enables rapid environmental sensing prototyping in smart home hubs and IoT edge nodes.

For engineers reviewing the SI7013USB-DONGLE datasheet, SI7013USB-DONGLE pinout, SI7013USB-DONGLE application, or SI7013USB-DONGLE equivalent, this dongle serves as a ready-to-use interface for validating SI7013 sensor performance, verifying I²C communication timing, evaluating humidity/temperature measurement stability under real-world conditions, and integrating environmental data into host MCU firmware via standard USB CDC ACM virtual COM port.

Technical Context

The SI7013USB-DONGLE implements a fixed-function USB HID-to-I²C bridge using Silicon Labs' CP2102N USB-to-UART bridge IC, configured to expose the SI7013 sensor's native I²C address (0x40) over a virtual COM port. It supports standard SI7013 command set including RH/T measurement triggers, heater control, and user register access.

No external power supply is required - the dongle draws 5 V USB bus power and regulates it to 3.3 V for the SI7013 and CP2102N. The board includes decoupling capacitors, ESD protection diodes on USB lines, and a status LED indicating USB enumeration success.

FAQ

What is the SI7013USB-DONGLE used for?

The SI7013USB-DONGLE is a USB evaluation tool that provides immediate access to the SI7013 relative humidity and temperature sensor via a virtual COM port. It allows engineers to read calibrated RH and temperature values without writing low-level I²C drivers. The SI7013USB-DONGLE is intended for lab validation, firmware interface testing, and environmental data logging during early-stage IoT product development.

Does the SI7013USB-DONGLE require external power or drivers?

No. The SI7013USB-DONGLE is fully bus-powered from USB 5 V and uses the standard CDC ACM class driver built into Windows, macOS, and Linux. No additional drivers or firmware installation is needed - once plugged in, it appears as a serial port. The SI7013USB-DONGLE includes all necessary regulation and level-shifting circuitry onboard.

Can the SI7013USB-DONGLE be used with custom host software?

Yes. The SI7013USB-DONGLE communicates using ASCII-based text commands over the virtual COM port (e.g., "READRH", "READT"). Host applications written in Python, C#, or Node.js can send these commands and parse returned JSON-like responses. The SI7013USB-DONGLE does not require proprietary software, though Simplicity Studio provides optional GUI visualization.

Is the SI7013 on the SI7013USB-DONGLE user-calibratable?

No. The SI7013 sensor on the SI7013USB-DONGLE is factory-calibrated and trimmed across temperature and humidity ranges. Its coefficients are stored in on-chip memory and automatically applied during measurement. Users cannot modify calibration data - the SI7013USB-DONGLE delivers out-of-box accuracy per the SI7013 datasheet specifications.

What is the maximum sampling rate supported by the SI7013USB-DONGLE?

The SI7013USB-DONGLE supports up to one RH/T measurement pair every 200 ms (5 Hz), limited by the SI7013's internal conversion time and USB polling interval. This rate is sufficient for room-level environmental monitoring but not for fast transient events. The SI7013USB-DONGLE does not support burst mode or hardware-triggered sampling.
