ESP32 Web-API that can provide sensor readings from DS18B20 temperature sensors on the network
- Import as a new PlatformIO Project in VS Code
- Set up your WiFi credentials:
- Create a new obfuscatedData.hpp header using my project Credentials Obfuscating Tool and place it in the lib/deobfuscate/src/ directory
- Alternatively: Change the WiFiHandler by adding your hardcoded credentials in the begin() function (C/C++ knowledge required)
- Compile and upload to an ESP32 using PlatformIO
The ESP32 is ready immediately after booting. You can read out debug information via the serial interface.
Send a GET (HTTP/1.0 or HTTP/1.1) request to the web server listening on default port 80.
e.g. GET SENSOR/TEMPERATURE/0/VALUE/C HTTP/1.1
SENSOR/TEMPERATURE/<n>/VALUE/<C|F> returns a float (format: %.2f):
21.75
Responses to SENSOR requests contain INVALID READ: -127 on failure.
ACTOR/BUZZER/<n>/OFF and ACTOR/BUZZER/<n>/ON[/<value>] (unit: milliseconds) return a string:
OK. Buzzer <n>: OFF|ON|BEEP/SIGNAL
Responses to ACTOR requests start with FAIL. (instead of OK.) on failure.
