+# ENV II
+
+SKU:U001-B
+
+
+
+## Description
+
+**ENV II** is an environment sensor which can sense temperature, humidity and atmospheric pressure. It is built with SHT30, BMP280 and BMM150 sensors, it is programmed over I2C. SHT30 is a digital temperature and humidity sensor with high precision and low power consumption. BMP280 is an absolute barometric pressure sensor which is especially designed for mobile applications. BMM150 is a magnetometer, which can be used to monitor the change of magnetic field and the direction of magnetic field.It offers the highest flexibility to optimize the device regarding power consumption, resolution and filter performance.
+
+## Product Features
+
+- Measurement of temperature, humidity, air pressure and magnetic field
+- High-precision
+- Support IIC
+- GROVE interface, support [UIFlow](http://flow.m5stack.com) and [Arduino](http://www.arduino.cc)
+- Two Lego installation holes
+
+
+## Include
+

+
+## Specification
+
+
+
+## EasyLoader
+
+>EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification. Please install the corresponding driver according to the device type. M5Core host [Please click here to view the CP210X driver installation tutorial](en/arduino/arduino_development), M5StickC/V/T/ATOM series can be used without driver)
