Adafruit SHT45 Trinkey - USB Temperature and Humidity Sensor

The Adafruit SHT45 Trinkey is a compact, USB-based environmental sensor that combines a temperature and humidity sensor with a USB A interface, making it easy to add accurate environmental readings to any computer or laptop.

This board features an ATSAMD21 microcontroller with built-in circuitry, a NeoPixel LED for visual feedback, and a capacitive touch input for user interaction. A reset button is also included for bootloader mode access when needed.

Key Features:

• SHT45 Sensor: High-accuracy temperature and humidity sensor from Sensirion, offering ±1.0% relative humidity accuracy (25–75%) and ±0.1°C temperature accuracy (0–75°C).
• Microcontroller: Powered by the ATSAMD21E18, a 32-bit Cortex M0+ processor running at 48 MHz, with 256KB of Flash and 32KB of RAM.
• USB Interface: Easily plugs into any USB A port for data transfer, supporting serial, MIDI, HID, and disk drive modes.
• Libraries Support: Fully compatible with CircuitPython and Arduino with available libraries for SHT4x, NeoPixel, and capacitive touch sensors.
• Pre-programmed: The Trinkey ships with pre-programmed code to print a unique serial number, temperature, humidity, and touch sensor data in CSV format over the serial/COM port for immediate use.
• User Interaction: One RGB NeoPixel LED for visual status feedback, and a capacitive touchpad for simple user input.
• Easy to Use: No soldering or drivers required—just plug it in, and you're ready to go!
• Compact Design: Slim, portable, and keychain-friendly, perfect for simple projects or as a starting point for more complex designs.

The SHT45 Trinkey is ideal for anyone looking to quickly add temperature and humidity sensing to their projects without extra wiring or setup. If you're looking for a more budget-friendly option with slightly lower precision, consider the SHT41 Trinkey.
