AHT10 IC2 RH Temp

Hey im trying to read the temperature and humidity from the AHT10 and im just stuck. I hook up the SCL an SDA with software ic2 and then i try to read on 0x38 and 0x39, 6 bytes.
The response is
[25,0,0,0,0,0]
And
[255,255,255,255,255,255]

These vales doesn't change when i change the temperature. Whats the next thing i could try ?

Just looked at the datasheet, but looks like some initialization is needed.
BTW looks like that guy is doing some serious testing: https://wiki.liutyi.info/download/attachments/35291508/Humidity_sensors_board_v7s1.jpg?version=1&modificationDate=1572380072453&api=v2 :)

Take a look at this GitHub repository for the AHT10 written in C++ which might be a nice starting point for writing you javascript code to get temperature and humidity.

Give it a try and share what you achieved or where you stuck.

Just a note that address 0x38 is almost certainly the right address to do the communications on. If 0x39 is returning 255 it's probably because the AHT10 isn't on that address

Well thank you all for your comments, you all made me realize it was doable hehe..

Maybe i can improve some stuff, like could probaly make the user send in the i2c instance so it can be used with other devices on the same pins ?

Cool, that was quick, thanks for sharing.

Thanks! http://www.espruino.com/AHT10

Yes, I think in general sending in the I2C instance is better - if only because that's what everything else does
