Description
ENV IV is an environmental sensor that integrates the SHT40 and BMP280 sensors, designed for measuring temperature, humidity, and atmospheric pressure data. The SHT40 is a high-precision, low-power digital temperature and humidity sensor, supporting the I2C interface (SHT40 address: 0x44). The BMP280, on the other hand, is an absolute pressure sensor known for its high accuracy in atmospheric pressure measurements, with an I2C address of 0x76. This sensor unit finds applications in various fields, including meteorological monitoring, indoor environmental control, agriculture and horticulture, and industrial automation.
