{"title":"Adafruit Sensirion SHT41 Temperature & Humidity Sensor","handle":"adafruit-sensirion-sht41-temperature-humidity-sensor","url":"/products/adafruit-sensirion-sht41-temperature-humidity-sensor","description":"The Adafruit Sensirion SHT41 is a high-accuracy temperature and humidity sensor with a true I2C interface, part of Sensirion's fourth-generation SHT4x family. Compared to the SHT40, the SHT41 offers significantly better accuracy across the full humidity range — ±2% typical over 0–100% RH versus the SHT40's ±3% worst case, and a maximum error of ±3% versus ±6%.\n\nThe breakout includes a voltage regulator and level shifting, making it compatible with both 3.3 V and 5 V systems. STEMMA QT / Qwiic connectors allow solderless hookup, and Arduino and CircuitPython libraries are available for quick integration.\n\nKey Features\n\n\nRelative Humidity Accuracy – ±1.8% RH typical (25–75% RH), ±2% typical over full 0–100% RH range\n\nTemperature Accuracy – ±0.2 °C typical (0–75 °C)\n\nImproved Full-Range Accuracy – Max ±3% RH error versus ±6% on the SHT40\n\nTrue I2C Interface – Address 0x44, fast mode plus with CRC checksum\n\nUltra-Low Power – Ideal for battery-powered applications\n\nVariable Power Heater – Built-in heater for defogging and self-testing\n\n3.3 V / 5 V Compatible – Onboard voltage regulator and level shifting\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection and daisy-chaining\n\n\nAlso Consider\n\n\nSHT40 Sensor – Lower-cost option with similar typical accuracy at 25–75% RH but reduced full-range accuracy\n\n\nIdeal For\n\nEnvironmental monitoring and weather stations\nHVAC and climate control systems\nIndoor air quality and comfort monitoring\nData logging and scientific experiments\n\n\nPackage Contents\n\n1× Adafruit Sensirion SHT41 Temperature & Humidity Sensor Breakout\n1× Header strip (soldering required for breadboard use)\n\n\n\nNote: STEMMA QT / Qwiic cable is not included. Use a compatible JST SH cable for solderless connection, or solder directly to the header pads.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1475,"title":"Default Title","sku":"AF-5776","price":11.87,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
