Adafruit this week announced the availability of its fully assembled Adafruit HTU21D-F temperature and humidity sensor breakout board, which is now available to purchase priced at $15.95. Measuring just 18mm x 16mm x 11.5mm and weighing 1.4 g, the tiny breakout board allows you to accurately measure a number of data points and offers an accurate and intelligent alternative to the much simpler Adafruit Humidity and Temperature Sensor, the SHT15 Breakout.
Features and Specifications
The Adafruit HTU21D-F temperature and humidity sensor offers a typical accuracy of ±2 percent with an operating range that’s optimized from 5 percent to 95 percent RH, says Adafruit. “Operation outside this range is still possible – just the accuracy might drop a bit. The temperature output has an accuracy of ±1°C from -30 – 90°C. If you’re looking to measure temperature more accurately, we recommend the MCP9808 High Accuracy I2C Temperature Sensor Breakout Board.”
In addition to its impressive accuracy, the HTU21D-F sensor is designed for ease of use. It communicates via I2C, which means it can be easily integrated into a variety of projects with minimal wiring. The sensor also features a low power consumption, making it ideal for battery-operated devices. The breakout board includes pull-up resistors for the I2C communication lines, which simplifies the connection process.
Applications and Use Cases
The versatility of the Adafruit HTU21D-F sensor makes it suitable for a wide range of applications. For instance, it can be used in environmental monitoring systems to track changes in temperature and humidity over time. This is particularly useful in agricultural settings where maintaining optimal conditions is crucial for crop health. Additionally, the sensor can be employed in HVAC systems to ensure that heating and cooling systems are operating efficiently.
Another potential application is in the field of home automation. By integrating the HTU21D-F sensor into a smart home system, users can monitor and control the climate within their homes more effectively. This can lead to improved comfort and energy savings. The sensor’s small size and lightweight design also make it an excellent choice for wearable devices that track environmental conditions, providing users with real-time data on their surroundings.
For hobbyists and educators, the HTU21D-F sensor offers a valuable tool for learning about sensor technology and data collection. Its straightforward interface and reliable performance make it an excellent addition to DIY electronics projects and classroom experiments. By using this sensor, students can gain hands-on experience with real-world applications of temperature and humidity measurement.
