I have a project that requires 3 aht20 sensors to measure temp and humidity in three air streams and was hoping to connect then in series to simplify wiring but not sure if that is possible. Is there a way to change the address of each sensor? I noticed experimental address tabs on the pcb, is hardware needed to change the addess?
Found this in the code. “We had hoped the AHT20 would support two addresses but it doesn’t seem to”. Looks like I need a multiplexer for i2c which is fine, I just wish the info was on the product page since now I have to pay for shipping on something I would have purchased the first time around.
For further reference; any multiplexer like SFE’s TCA9548A board or any other of the same type should play nice with multiple sensors.
