 ##  Description
 
-**BTC** is a M5 base that allows you sit your M5 core instead of laying them down or hang on the wall. BTC is not just a sit for holding the M5 core but also comes with serveral features like temperature and humiluty detection(by DHT12), and charging base.
+**BTC** is a M5 base that allows you sit your M5 core instead of laying them down or hang on the wall. BTC is not just a sit for holding the M5 core but also comes with serveral features like temperature and humiluty detection(by SHT30), and charging base.
 
 **Note:**
 
 * Although M5Core [BASIC](https://docs.m5stack.com/#/en/core/basic) or [GRAY](https://docs.m5stack.com/#/en/core/gray) can be attached to this base, but BTC can not charge them. Actually, our Cores, as we know, are built in chargin chip (IP5306). After plugged a USB cable in, the Core was charging without any charger.
 
-* Once M5Core has been attached to BTC, it can not controll ENV Unit at this time. Because BTC has been built in DHT12 sensor which will cause IIC address conflict.

+**BTC** 是一款集成了"SHT30"的温湿度传感器底座，除了用作固定M5Core之外，运用其内置的温湿度传感器能够制作环境监测器或是一些与环境数据采集相关的应用.
 
 **注意:**
 
 * 兼容BTC底座的有 [BASIC](https://docs.m5stack.com/#/zh_CN/core/basic) 与 [GRAY](https://docs.m5stack.com/#/zh_CN/core/gray) 两款主控，当将USB线连接BTC底座，仅对M5Core的电路板进行供电，并不会为其内部的锂电池充电.只有将USB线连接至M5Core时，才会对M5Core电池充电且同时为电路板供电.
 
-* 当M5Core连接至BTC底座后，将无法同时控制 ENV Unit.这是因为在 BTC 已经内置了DHT12传感器，两者将产生 I2C 地址冲突.
