SENSEVAL-SCB4XV1
Evaluation board for SHT4x temperature and humidity, SGP40 VOC and STMicroelectronics LPS22DF barometric pressure sensors
This evaluation board features a unique combination of SHT40 humidity and temperature sensor, SGP40 VOC sensor and an STMicroelectronics LPS22DF barometric pressure sensor and is compatible with the STMicroelectronics DIL 24 socket.
The combo board allows the users to measure and understand the indoor air quality around them and easily identify potentially harmful events.
It is supported by the STEVAL-MKI109V3 motherboard and compatible with the X-NUCLEO-IKS4A1 and X-NUCLEO-IKS02A1 expansion boards from STMicroelectronics. From evaluation to prototyping, the SENSEVAL-SCB4XV1 will help you bring your ideas to life.
