The bees are important. Unfortunally, taking care of a bee hive is a time intensive prosess. Thus, we attempt to make the prosess less time consuming by developing Bee CTRL, an opensource monitoring and allerting system which can be installed in a bee hive.
Great question! Bee CTRL consist of the following sensors:
- 4x TMP117 sensors
- 2x BME280/CSS811 sensors
- 1x MLX90640
- Flash your Raspberry Pi.
- Make sure your raspberry pi is connected to the internett.
- Setup I2C on your raspberry pi.
To install rust on your raspberry pi, run this command in your terminal, and grab yourself a cup of coffee with your favorite honey:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Rust is a new language, created in 2010. Similar to C++, its a memory safe language that has been voted the "most loved programming language" in the Stack Overflow developer survey the last couple of years.
As an example, we will be using Heroku to host our database.
First, follow this guide.
To set up our rust app, install diesel by running the following command in your terminal, and continue enjoying your favorite hot beverage with some honey:
cargo install diesel_cli --no-default-features --features postgres
Grab your postgres url from Heroku, and copy it into your .env file. It will look something like this inside the .env file:
DATABASE_URL=postgres://username:password@localhost/diesel_demo
Now, you can run cargo run migration to setup your database.
Due to the limited resources on a raspberry pi, we will crosscompile the program, i.e compile it locally for another machine. To do this, we will instneed cross, which we can install by running:
cargo install cross
This will install the cross command line application, which we can use to compile the code for our RPI.
To compile for a RPI 4, run:
cross build --target armv7-unknown-linux-gnueabihf --release
To compile for a RPI Zero w, run:
cross build --target armv-unknown-linux-gnueabih
To only build the binary, run:
cargo build
To change your refreshrate, you can either do it the following way when using cargo run:
cargo run -- -r 1 # To set the refresh rate as 1HZ
Or if you built the binary:
./target/release/bee_ctrl -r 1
