DS18B20 Remote Sensor

This is a simple program to periodically read temperatures from 1-Wire sensors and send them to a specified endpoint. Easy to run as a systemd service. Below is my systemd unit configuration file.

[Unit]
Description=sending temperature readings
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
ExecStart=/home/pi/ds18b20-remote-sensor/ds18b20-remote-sensor start
WorkingDirectory=/home/pi/ds18b20-remote-sensor
Restart=on-failure
User=pi
Group=pi

[Install]
WantedBy=default.target

The code is written and tested with Go. It works flawlessly 24/7. I chose to send JSON using HTTP POST requests to fit both standard and serverless architecture.

I personally run it on a cheap Raspberry Pi Zero W in a dusty environment. There are probably cheaper solutions as you only need a way to get readings from the sensors and send those values.
