## Description

The Adafruit SHT45 Trinkey is a tiny USB A device that combines an ATSAMD21 microcontroller with Sensirion's highest-precision SHT45 temperature and humidity sensor, protected by a PTFE filter. Simply plug it into any USB A port on your computer and start reading environmental data — no wiring, soldering, or driver installation required. The board ships pre-programmed to output a unique serial number, temperature, humidity, and capacitive touch data over a serial/COM port in CSV format, so it works straight out of the box. Reprogram it with CircuitPython or Arduino to customise the behaviour, add HID or MIDI functionality, or create your own sensor applications. Key Features SHT45 Sensor with PTFE Filter – ±1.0% RH typical accuracy (25–75% RH) and ±0.1 °C typical temperature accuracy (0–75 °C); PTFE protects against dust and water ATSAMD21E18 Processor – 48 MHz Cortex M0+ with 256 KB flash and 32 KB RAM USB A Plug – Plugs directly into any computer's USB port, no cable needed Pre-Programmed – Ships with CSV serial output of temperature, humidity, and touch data NeoPixel LED – Single RGB LED for visual feedback Capacitive Touch Pad – One touch input on the end of the board Native USB – Serial (CDC ACM), MIDI, and HID (keyboard/mouse) support across all major OSes CircuitPython & Arduino – Full library support for SHT4x, NeoPixel, and FreeTouch Thermal-Isolation Cutout – PCB cutout reduces heat transfer from USB port to sensor Tip: The reported temperature may be a few degrees higher than ambient due to self-heating from the USB port. Use a USB A extension cable for more accurate ambient readings or to measure at a distance from the computer. Also Consider SHT41 Trinkey – Lower-cost version with ±1.8% RH and ±0.2 °C accuracy (no PTFE) SHT45 Breakout with PTFE – Standalone SHT45 sensor with STEMMA QT for use with any microcontroller Ideal For Precision desktop temperature and humidity monitoring Data logging without additional hardware Environmental monitoring for server rooms or offices Simple USB sensor projects and prototyping Package Contents 1× Adafruit SHT45 Trinkey with PTFE (pre-programmed, ready to use)
