Generic digital humidity temperature sensor polling
Overview
This sample application demonstrates how to use digital humidity temperature sensors.
Building and Running
This sample supports up to 10 humidity/temperature sensors. Each sensor needs to
be aliased as dhtN where N goes from 0 to 9. For example:
/ {
aliases {
dht0 = &hs300x;
};
};
Make sure the aliases are in devicetree.
It also requires a correct fixture setup when the sensor is present. For the correct execution of that sample in twister, add into boards’s map-file next fixture settings:
- fixture: fixture_i2c_hs300x
Then build and run with:
west build -b <board to use> samples/sensor/dht_polling
west flash
