UPDATED PRODUCT – Adafruit HDC3022 Precision Temperature & Humidity Sensor – STEMMA QT / Qwiic
______________________________________________________________________________
We inventory a lot of Temperature/Humidity sensors, so that you’re most likely questioning why one other one? Properly, this Adafruit HDC3022 Precision Temperature & Humidity Sensor breakout options the best accuracy & precision one we’ve see to this point! It has the TI HDC302x sequence chip with typical 0.5% accuracy for the RH sensor (with 0.19% long-term drift) and ±0.1°C typical accuracy for the temperature sensor. All at a really good worth.
New! As of September 23, 2024 – We’ve upgraded this sensor to now be the “HDC3022” slightly than the “HDC3021”. It’s fully the identical apart from it now has a white PTFE filter cowl that shouldn’t be eliminated and can maintain your sensor good and clear
This sensor has a real I2C interface for straightforward interfacing with solely two wires (plus energy and floor!). That makes it preferable to the janky DHT11/DHT22 sensors. The sensor is 5V protected, so you should use 1.8V to 5V energy and logic ranges with out the necessity for shifters, so you possibly can energy and talk with it utilizing any microcontroller or microcomputer. With 4 selectable I2C addresses, you possibly can have a number of sensors on one bus – in contrast to many different fixed-address T/RH sensors.
We’ve written a full-featured Arduino and CircuitPython/Python library, so whether or not you might have an 8-bit microcontroller or a quad-core Raspberry Pi, it is possible for you to to rapidly get information from the sensor to your environmental monitoring wants. The library can setup the sensor price/energy, heater, alerts, offsets, and browse information or NIST monitoring ID.
Such a stunning chip – so we spun up a breakout board with the HDC3022 and a few supporting circuitry similar to pullup resistors and capacitors. To make issues even simpler, we’ve included SparkFun Qwiic appropriate STEMMA QT connectors for the I2C bus so that you don’t even have to solder! QT Cable is just not included, however we now have a spread within the store.
In the event you desire engaged on a breadboard, every order comes with one absolutely assembled and examined PCB breakout and a small piece of header. You’ll have to solder the header onto the PCB, nevertheless it’s pretty simple and takes just a few minutes even for a newbie.
Please notice: this sensor comes with a protecting polyamide sticker on prime, please take away earlier than utilization!
