This study designs an automatic control system for biogenic shallow gas filling using a PLC based on ESP32, with monitoring via a Telegram Bot. A pressure transmitter sensor measures pressure in real-time, and hysteresis logic controls the compressor operation within a range of 1–3 bar. Pressure values are displayed on the Serial Monitor and sent to Telegram. Test results show that the system operates stably and accurately, with sensor deviation less than ±0.1 bar. The average filling rate is 0.123 bar per minute, and the compressor temperature remains within safe limits. The Telegram Bot responds quickly and provides data that accurately reflects the device’s condition. This system is effective for automatic filling and remote monitoring.
