dht-logger
Read DHT sensor data formatted in JSON over a serial interface and log it.
This crate is still under development and is not stable.
This crate is for logging measurement from a device reading DHT sensors and writing the measurements over a serial connection. The hardware producing the data does not matter, but it must be logging data over serial in JSON with fields for temperature, humidity, and heat index. Here's a pretty version of an example reading:
This code has been tested using arduino-dht-logger as the hardware source providing data over serial.
Example
The following example creates a DHT logger from a configuration file, then reads data from the serial port and logs it to whatever logging channels are configured.
use Path;
use DhtLogger;
let config_path = new;
let config = load_yaml;
let logger = from_config;
logger.read_sensor_and_log_data;
Cross compiling for the Raspberry Pi
The cross-compilation procedure for Raspberry Pi is modified from rust-embedded/cross as libudev-dev is required for compilation, which isn't in the default docker images cross provides. Currently the Raspberry Pi Zero and 4B models are supported. To set up the cross-compilation for both the 4B and zero, run the bootstrap script:
./bootstrap.sh
After ./bootstrap.sh
is finished, the build.sh
script can be run with
either 4b
or zero
as the arguments to determine the target.
