Sensirion SENSEVAL-SCB4XV1 Evaluation Board

Sensirion SENSEVAL-SCB4XV1 Evaluation Board simplifies sensor evaluation and prototyping for the Sensirion SHT40, SGP40, and STMicroelectronics LPS22DF. The board is compatible with the STMicroelectronics DIL 24 socket and supported by the STEVAL-MKI109V3 motherboard and STM32Nucleo boards. The combination of sensors on this board allows ideas requiring relative humidity, temperature, volatile organic compounds, and barometric pressure to be evaluated. The device can be a platform for evaluating individual sensors and prototyping ideas using one or multiple sensors.
