Temp&Hum 20 Click Board™

Product Code: MIKROE-4907

How Does The Temp&Hum 20 Click Board™ Work? The Temp&Hum 20 Click Board™ is based on the CC2D23, a highly accurate, fully-calibrated relative humidity and temperature sensor from Amphenol. The humidity can be measured within a range of 0 to 100 %RH, while the temperature sensor is designed for a range of -40 to +125 °C. The typical accuracy for humidity is ±2 %RH in the measuring range of 20 up to 80 %RH at ambient temperature, and ±0.3 °C for its operating temperature range with very low power consumption. The Temp&Hum 20 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data supporting Standard Mode operation with a clock frequency up to 100kHz, providing factory-calibrated 14-bit data to the host controller. The Temp&Hum 20 Click Board™ also possesses enabling function managed by SiP32431DN, a high side switch with reverse blocking capability. The Enable pin, labeled as EN and routed to the CS pin of the mikroBUS™ socket, activates the SiP32431DN, allowing and powering the main IC the CC2D23 (used for power ON/OFF purposes), and thus enables optimizes power consumption.

It also comes with alarm features, labelled as ALH and ALL and routed to the AN and PWM pins of the mikroBUS™ socket, for preset control at a minimum and maximum humidity, and additional data-ready signal routed on the INT pin of the mikroBUS™ socket indicating that new data is ready for the host. The Temp&Hum 20 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Temp&Hum 20 Click Board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
