This week, Adafruit announced the release and availability of the new Sensirion SHT41 Temperature and Humidity Sensor. A fourth generation of Sensirion I2C temperature and humidity sensors, with excellent accuracy of ±1.8% typical RH and typical accuracy of ±0.2°C.
the Adafruit Sensirion SHT41 Temperature and Humidity Sensor It has better accuracy over the full humidity range than the SHT40, with a typical accuracy of ±2% over the range 0-100%RH, and a maximum accuracy of ±3%. It has the same typical accuracy of ±1.8% RH from 25-75% as the SHT40, but it’s not much more expensive. For the “best” of the SHT4x series, check out the SHT45. A true I2C interface is included for easy interface with just two wires, and is 3V or 5V compatible, allowing it to be powered and communicated with any microcontroller or microcomputer.
Temperature and humidity sensor
The sensor can provide accurate relative humidity measurements with a margin of error of up to ±1.8%RH. In addition, it can provide temperature measurements with an accuracy of ±0.2°C. The breaker supply voltage corresponds to a range of 3.3 to 5 V, and the sensor has an average bare sensor current of 0.4 µA at a measurement rate of 1 Hz.
At idle, the sensor’s bare current is only 80 nA. In addition, the sensor supports I2C fast mode as well as CRC checksum for reliable data transmission. Adafruit wrote Arduino and CircuitPython/Python library code for this chip, so you can use it with any microcontroller or single-board computer such as a Raspberry Pi.
The sensor operates within a wide range of 0…100% RH and -40…125°C, and is fully functional even in condensing environments. It also features a variable power heater to ensure accurate measurements in difficult conditions. The sensor is NIST traceable, ensuring it meets the highest calibration standards. It has also been qualified according to JEDEC JESD47 standards.
This technology was developed by Sensirion, the global market leader in sensor technology. The sensor’s I2C address is 0x44, which makes it easy to integrate into your system. With these features, the sensor is a reliable and accurate choice for your humidity and temperature measurement needs. For more information on purchasing options, go to the Adafruit online store where the sensor is now available for purchase at $5.95.
