Water and Electricity (Energy) Usage Monitoring

an iot plant monitoring device

This channel aims to monitor the performance of a mini solar panel system and its capability in power and energy generation to meet load demands.

Channel ini digunakan untuk memantau tombol keypad yang menyalakan buzzer pada ESP32. Setiap tombol mewakili satu nada musik (Do, Re, Mi, Fa, So, La, Si, Do tinggi) yang akan dikirim ke ThingSpeak saat ditekan melalui web server.

This channel monitors and logs real-time freezer temperature using a DS18B20 sensor and ESP32. Safety levels are indicated using LEDs and data is sent every second via MQTT.
