Unit ENV-II
SKU:U001-B
Description
Unit ENV-II is an environmental sensor that integrates SHT30 and BMP280 internally for detecting temperature, humidity, and atmospheric pressure data. SHT30 is a high-precision, low-power digital temperature and humidity sensor that supports the I2C interface (SHT30: 0x44, BMP280: 0x76). BMP280 is an absolute pressure sensor designed for mobile applications with high accuracy. It is suitable for use in small, low-power terminals. For projects that require quick collection and detection of environmental data, Unit ENV-II is a good choice that balances performance and cost-effectiveness.
