Connect two SEN0546 to ESP8266
Duarte.Cota 2023-02-03 04:44:57 192 Views3 Replies I need to connect two SEN0546 I2C Temperature & Humidity Sensor to ESP8266.
Is this possible only by assigning a diferent address to the second? In this case what would be the address (i am using 0x40 on the first))
Thank you.

Hi
The I2C address of SEN0546 is fixed at 0x40. In this situation, Gravity: Digital 1-to-8 I2C Multiplexer is recommended to use, which can solves the address conflict and enables the normal communication with multiple same-address I2C devices.
See https://www.dfrobot.com/product-1780.html
Hope it can help!
