Arduino part of solution for measuring water level in tank. Arduino only collects data from ultrasonic sensor and sends them via RESTful api to to backend where all calculation are done.
Ultrasonic sensor is attached to the top cover of tank and measures distance of water level from it.
Other parts of solution
- Arduino
- Ultrasonic sensor
- ESP8266 Wifi module
To connect your wifi you must edit esp8266_secrets.h file and set correct SSID and password
IP address, port and HTTPS certificate SHA1 fingerprint of RESTful API must be also set in esp8266_secrets.h file.
