Couldn't load pickup availability
The Temp&Hum 16 Click Board™ is a compact add-on board that represents temperature and humidity sensing solutions. This board features the WSEN-HIDS (2525020210001), a MEMS-based capacitive humidity sensor with an integrated ASIC and I2C and SPI serial communication from Würth Elektronik. A silicon-based temperature sensor is also integrated within the same package. ASIC contains the multiplier, operational amplifier, analogue-to-digital converter, and other signal conditioning blocks like controller logics and interrupts.
The Temp&Hum 16 Click Board™ converts the analogue signal from humidity and temperature sensing elements into 16-bit digital humidity and temperature values. The WSEN-HIDS is factory calibrated for both humidity and temperature measurements with no further calibration required. This Click Board™ is an ideal solution to be used in various temperature and humidity-related applications.
How Does The Temp&Hum 16 Click Board™ Work?
The Temp&Hum 16 Click Board™ as its foundation uses the WSEN-HIDS, a 16-bit digital ultra-low-power and high-performance humidity sensor with digital output interface and embedded temperature sensor for ambient temperature measurement from Würth Elektronik. It measures relative humidity from 0 to 100% RH with an output data rate of up to 12.5Hz. The sensor is fully calibrated with no further calibration required. The initialization of the sensor can be performed by selecting the operation mode (Continuous or One-shot) and output data rate.
After initializing the sensor, it is recommended to check the availability of data samples using an interrupt signal labelled RDY and routed to the INT pin on the mikroBUS™ socket. By default, after powering up, the sensor goes to power-down mode. In power-down mode, all internal blocks are turned off to minimize power consumption. After selecting one of the two operating modes, the sensor is in an active measurement state depending on the output data rate.
The Temp&Hum 16 Click Board™ provides the possibility of using both I2C and SPI interfaces with a maximum frequency of 100kHz in Standard and 400kHz in Fast mode for I2C and 8MHz for 3-wire SPI communication. 3-wire SPI shares a single data line for the data transfer, where the Master and Slave alternate their transmitter and receiver roles synchronously. The communication interface selection can be made by positioning SMD jumpers labelled COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or else the Click board™ may become unresponsive.
The Temp&Hum 16 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Additional Notes and Information
Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The Temp&Hum 16 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
