Example using ESP8266 to send data to Wireless Monitor configured to monitor a Temperature sensor, Texas Instruments' LM35.
Getting Started
Edit your Wi-Fi configuration at:
const char* ssid = "";
const char* password = "";Edit Wireless Monitor configuration. For that you need a server running.
Configuration with HTTPS support (Recommend):
const String host = "";
const int port = 443;
const String api_key = "";
const String monitor_key = "";
// change this with an actual fingerprint
String httpsFingerprint = "FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF:FF";Also you need to pass httpsFingerprint as parameter to http.begin function.
Where do I find the fingerprint?
On Google Chrome open Chrome DevTools (Ctrl + Shift + i), click on Security tab >
View Certificate. The fingerprint is the SHA-1 Digital Signature.
Configuration with plain HTTP:
const String host = "";
const int port = 80;
const String api_key = "";
const String monitor_key = "";Compiling and running in Arduino IDE
