Product Description

It's half USB Key, half temperature-humidity sensor... it's the Adafruit SHT45 Trinkey. We wanted to make it super-easy to add one of our most popular combination environmental sensors to any computer with a USB A port.

The PCB is designed to slip into any USB A port on a computer or laptop. There's an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to a NeoPixel LED. Another pin is used as a capacitive touch input on the end. A reset button lets you enter bootloader mode if necessary. That's it!

The SAMD21 can run CircuitPython or Arduino very nicely - both have existing SHT4x, NeoPixel, and our FreeTouch (capacitive touch) libraries. Over the USB connection, you can have serial, MIDI, or HID connectivity.

The star of this Trinkey is the SHT45 from Sensirion. Sensirion Temperature/Humidity sensors are some of the finest and highest-accuracy devices you can get. The SHT45 sensor is the fourth generation (started at the SHT10 and worked its way up to the top!). The SHT45 has an excellent ±1.0% typical relative humidity accuracy from 25 to 75% and ±0.1°C typical accuracy from 0 to 75 °C. Note that the reported temperature may be a few degrees higher than ambient due to self-heating.

If you don't need high precision, save a few $ with the SHT41 Trinkey which has ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2°C typical accuracy from 0 to 75 °C.
