www.winsen-sensor.com Data interface Power Supply Pin: (VCC GND) The ZS05 has a supply voltage range of 3.3V - 5.5V. Serial Clock Input: (SCL) The SCL pin is the clock line for IIC communication. Serial Data (SDA): The SDA pin is a three-state structure for reading and writing sensor data. IIC communication protocol The ZS05 supports the IIC mode for communication. It is compiled according to the IIC standard protocol and can be directly hung on the IIC bus. The sensor SDA pin is connected to the IIC data bus, and the SCL is connected to the IIC clock bus. When using it, the two pins must be...

Fig5.IIC read timing diagram Fig6.Reference timing diagram Data Format The data is divided into a fractional part and an integer part. A complete data transmission is 40bit, and the high order is first out. Data format: 8bit humidity integer data+8bit humidity decimal data+8bit temperature integer data+8bit temperature decimal data +8bit checksum When the data is transmitted correctly, the checksum data is equal to the last 8 digits of the result of "8bit humidity integer data + 8bit humidity decimal data + 8bit temperature integer data + 8bit temperature decimal data". Note: The fractional part...
