About This Product
For the makers, tinkerers, and weather geeks – check out this 3-pack of HTU21D sensor modules!
These little boards are perfect for measuring temperature and humidity in your DIY projects.
They’re super accurate, easy to use, and work from 1.5V to 3.6V, so they’re great with Arduino, Raspberry Pi, or other microcontrollers.
Communication is via I2C, so wiring is simple: just connect VCC, GND, and two data pins.
The HTU21D gives you humidity readings from 0 to 100% RH with an accuracy of ±2%, and it responds fast.
It’s a low-cost alternative to sensors like the SHT20 or SHT21, but doesn’t skimp on performance.
Use it for weather stations, greenhouse monitoring, humidor control, data logging, or any project where you need reliable environmental sensing.
Each module is compact and ready to plug into your setup.
Whether you’re a beginner or a seasoned pro, these sensors are a reliable, affordable way to add climate sensing to your creations.
Grab a pack and start building something smart!
