Hi, is it possible to add support for si7021 sensor in the next version? tnk for your work

dakipro commented 6 years ago

I was just about to ask for this sensor :) Looking forward to it!

Hi, thanks for raising this! If I'm not wrong, the SI7021 should work with the same SHT21 library. May you please connect the SI7021, try enabling MODULE_SHT21 and adding a SENSOR_SHT21 sensor to nodemanager? If i would work I'll make it an alias like I did for SENSOR_HTU21D. Thanks

Thanks, I am waiting for more parts and boards to arrive, I will test and confirm (but can take some time :( )

any update for this ? I tried with SENSOR_HTU21D but no luck

user2684 commented 6 years ago

Strange, I have a few of those https://www.aliexpress.com/item/Humidity-Sensor-with-I2C-Interface-Si7021-for-Arduino-Industrial-High-Precision/32687207471.html and SENSOR_SHT21/SENSOR_HTU21D did work for me. Which module are you using? Do you have a link of the arduino library which is working for your module? Thanks

@user2684 When I use "SparkFun_Si7021_Breakout_Library.h" it works fine. I can get temperature and humidity measurements without any issue, however the recommended method here didn't work.

Thanks. Having a look at the library you are using, it is definitely different from the SHT21's. This means we need to implement a brand new sensor. I'll add it to the v1.7 backlog then. Thanks!
