Product Details
The MIKROE Temperature and Humidity 15 Click is a compact add - on board. It comes with the 4th - generation SHT humidity sensing solution from Sensirion, one of the best in its class. At its heart is the SHT40, a high - accuracy, ultra - low - power 16 - bit sensor for relative humidity and temperature. This sensor offers constant temperature accuracy up to 0.1°C and performs best within the recommended temperature range of 5 - 60°C and humidity range of 20 - 80%RH. It provides linearized digital output, NIST traceability, and I2C Fast Mode Plus, and can be reflow soldered and work in condensing environments. It's a perfect choice for various temperature and humidity - related applications. The SHT40 is built on a new and optimized CMOS chip, reducing power consumption and improving accuracy. It has a fully calibrated digital I2C Fast Mode Plus interface for quick data transfer. It can operate from 0 to 100%RH and - 40°C to 125°C with accuracies of ±1.8%RH and ±0.2°C. The sensor also has a power - trimmed internal heater with three heating levels for use in tough conditions. Long - term exposure outside the recommended range, especially at high humidity, may cause a temporary offset in the RH signal, but it will recover on its own when back in the recommended range. This Click board communicates with the MCU via a standard I2C 2 - Wire interface. With the PCA9306 voltage - level translator from Texas Instruments, it can work with both 3.3V and 5V MCUs. You can select 3.3V or 5V logic voltage levels via the VIO SEL jumper. The board comes with a library having easy - to - use functions and example code for further development. Features include an I2C interface, mikroBUS™ compatibility, dimensions of 28.6 x 25.4mm, input voltage options of 3.3V or 5V, temperature accuracy of ±0.2°C, relative humidity accuracy of ±1.8%RH, a resolution of 0.01%RH, and operating humidity and temperature ranges from 0%RH to 100%RH and - 40°C to 125°C. Available documents are the schematic, SHT40 Datasheet, mikroSDK, and GitHub resources.
Using the MIKROE Temperature and Humidity 15 Click Board is quite straightforward. First, connect it to your MCU via the I2C 2 - Wire interface. You can select either 3.3V or 5V logic voltage levels using the VIO SEL jumper according to your MCU's requirements. The board's library has easy - to - use functions and example code that you can refer to for further development. For best performance, operate the board within the recommended temperature range of 5 - 60°C and humidity range of 20 - 80%RH. Long - term exposure to conditions outside this normal range, especially high humidity, may cause a temporary offset in the humidity signal. But don't worry, the sensor will recover on its own when you bring it back to the recommended range. When it comes to maintenance, keep the board clean and free from dust. Since it can be reflow soldered, if there are any connection issues, you can address them using proper soldering techniques. Just make sure to follow safety procedures when handling soldering equipment.
