Mikroe Environment 2 Click features an SHT humidity and SGP air-quality sensing solutions from Sensirion. The board features the SHT40 and SGP40 high-accuracy ultra-low-power relative humidity, and a temperature sensor combined with MOx based gas sensor. The SHT40 sensor offers linearized digital output, and provides constant temperature accuracy, up to 0.1°C. It shows the best performance when operated within the temperature and humidity range of 5-60°C and 20-80%RH. The SGP40 digital gas sensor features a temperature-controlled micro hot plate providing a humidity-compensated VOC-based indoor air quality signal.
