Adafruit SHT45 Trinkey - USB Temperature and Humidity Sensor with PTFE

The USB Temperature and Humidity Sensor Trinkey is a compact, USB-compatible board featuring an ATSAMD21 microcontroller and an SHT45 temperature and humidity sensor from Sensirion. It’s designed to easily slip into any USB-A port on a computer or laptop, offering a simple setup with minimal wiring or soldering. The microcontroller interfaces with a NeoPixel LED and a capacitive touch input, with a reset button to enter bootloader mode if needed. USB Temperature and Humidity Sensor supports both Circuit Python and Arduino, with libraries for SHT4x sensors, NeoPixel, and capacitive touch. The USB Temperature and Humidity Sensor offers high accuracy, with ±1.0% RH and ±0.1°C temperature accuracy, making it ideal for simple temperature and humidity measurement projects. The board is pre-programmed to output temperature, humidity, and touch sensor data over a serial port in CSV format, ready for use right out of the box. For those on a budget or needing lower accuracy, the SHT41 Trinkey offers a more affordable alternative. With its small, durable design, the SHT45 Trinkey is perfect for both beginners and advanced developers looking for an easy-to-use and versatile solution.
