ENV IV is a compact environmental sensor module that combines the power of the SHT40 and BMP280 sensors. It measures temperature, humidity, and atmospheric pressure with high preci sion and low power consumption. The SHT40 provides accurate digital temperature and humidity readings via an I2C interface (address: 0x44), while the BMP280 delivers reliable atmospheric pressure measurements (I2C address: 0x76). ENV IV is ideal for meteorological monitoring, smart indoor environments, agricultural projects, and industrial automation. Features Integrated high-precision SHT40 (temperature/humidity) & BMP280 (pressure) sensors Low power operation I2C communication (SHT40: 0x44, BMP280: 0x76) Real-time environmental data monitoring Compatible with Arduino and UIFlow for easy development Includes 1x ENV IV Unit 1x 20cm Grove Cable Applications Meteorological data collection Indoor air quality monitoring Smart agriculture and horticulture Industrial automation systems Specification Resources Parameters SHT40 measure range (Temperature/Humidity) -40 ~ 125 °C, 0 ~ 100 %RH BMP280 measure range (Pressure) 300 ~ 1100 hPa SHT40 measure accuracy ±0.1 °C, ±1.5 %RH BMP280 measure accuracy ±0.12 hPa Communication protocol I2C: SHT40(0x44), BMP280(0x76) Shell material Plastic (PC) Product Size 32 × 24 × 8 mm Package Size 136 × 92 × 13 mm Product Weight 3.9 g Package Weight 9.3 g ENV IV Unit Demo ENVIV Unit show TEM\HUM\Pressure Arduino Demo Show more
