TinyGo: Getting the upper hen

This project holds all the needed code to build a monitoring system for a henhouse.

Quickstart

Prerequisites:

• Install go, tinygo, kubectl, helm, kind

First deploy the cluster, it will take a few minutes, go get the water boiling during this time.

make deploy

You can test (even you do not have an Arduino board) by sending a measure:

 make curl_measure

You should expect a 200 HTTP answer:

< HTTP/1.1 200 OK
< Date: Thu, 14 Jul 2022 17:55:02 GMT
< Content-Length: 0
< Connection: keep-alive

Hardware setup

The needed material are

• an Arduino Nano 33 IoT or an equivalent board with a WiFi antenna
• a DHT sensor to measure temperature and humidity

You can then flash the tinygo program on your board using this command.

tinygo flash -target=arduino-nano33 <yourpath>/tiny-hen/

Then read from the serial port. To find it, you can use the following command, using tab to autocomplete the usb modem number:

ll /dev/cu.usbmodem1421

 go run utils/read_serial.go -port /dev/cu.usbmodem1101 

Now it should send data.
