Features Features: The sensor can measure not only pressure and temperature, but also humidity. It is a precision sensor, soldered on the PCB. Also suitable for low-power applications such as wearables. Durable Materials: The sensor is made with high-quality electronic components for durability. Small in size, light in weight and easy to use, it is ideal for monitoring air quality. High Precision: Sensitive sensor, high development board. It consists of a very accurate pressure sensor and an associated temperature sensor that helps calibrate pressure readings. ​​What It Does: The I2C connection gives you access to enough weather data to make some really good forecasts for your area. The on-board power regulation chip and level signal conversion chip have good compatibility. Ease of Use: It uses both I2C and SPI (supports 3-wire, 4-wire SPI) interfaces. Individual humidity, pressure and gas sensors can be enabled/disabled independently. Features: 1.This is a sensor board of temperature, humidity and pressure. 2.Made of premium electronic components, the sensor is durable. 3.Small size and light weight, convenient to use. 4.The sensor is sensitive, a great height development board.
