It's half USB Key, half temperature-humidity sensor—it's the Adafruit SHT45 Trinkey with a PTFE filter. Designed to easily integrate into any computer with a USB A port, this device features an ATSAMD21 microcontroller capable of running CircuitPython or Arduino smoothly.Specifications: * ATSAMD21E18 32-bit Cortex M0+ - 48 MHz processor * 256KB Flash and 32KB RAM * SHT45 sensor with ±1.0% relative humidity and ±0.1°C temperature accuracy * RGB NeoPixel LED * Capacitive Touchpad * Reset switch for bootloader mode Perfect for projects needing ambient temperature and humidity data, this Trinkey eliminates the need for extra wiring or complex software. The board comes pre-programmed to output temperature and humidity data over a serial port in CSV format, allowing immediate use. For extended range, use a USB A extension cable.This compact and durable device offers USB connectivity, functioning as a serial console, MIDI, or HID with multiple OS support. Its slim and adorable design makes it keychain-friendly and accessible for both newcomers and experienced developers alike. https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2025-11-11 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2025-12-04 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2025-12-06 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2025-12-20 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-01-10 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-01-24 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-01-27 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-01-29 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-02-01 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-02-06 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-02-12 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-02-20 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-03-06 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-03-13 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-03-25 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-03-27 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-04-02 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-04-08 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-04-13 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-04-16 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-04-20 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-07-01 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-08-02 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-09-24 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-10-02 https://elecena.pl/product/29498222/adafruit-sht45-trinkey-usb-temp-and-humidity-sensor-with-ptfe 2026-10-06
