Sensirion SEK-SVM4x Air Quality Sensor Evaluation Kit

Sensirion SEK-SVM4x Air Quality Sensor Evaluation Kit is a plug-and-play development tool for fast evaluation and prototyping of the SGP40, SGP41, and SHT4x sensors for VOC and NO_x measurements. The SEK-SVM4x provides an onboard microcontroller for signal processing and an I²C and UART interface with digital output signals. Other features include a 3.0V to 5.5V supply voltage range, a 3.0mA maximum idle current, and a -20°C to +55°C operating temperature range. The evaluation kit consists of a sensor module equipped with an SGP41 and SHT40 sensor, a USB-UART cable, and a jumper wire cable set.
