Unit ENV-IV
SKU:U001-D
Description
Unit ENV-IV is an environmental sensor unit embedded with SHT40 and BMP280 sensors for measuring temperature, humidity, and atmospheric pressure data. The SHT40 is a high-precision, low-power digital temperature and humidity sensor that supports the I2C interface (SHT40 I2C address: 0x44). The BMP280 is an absolute pressure sensor that provides high-precision atmospheric pressure measurements (BMP280 I2C address: 0x76). It is suitable for meteorological monitoring, indoor environment monitoring, agriculture and horticulture, and industrial automation.
