Modul sensor gas MQ-TGS

Deskripsi

Modul yang dikembangkan merupakan breakout board antarmuka sensor gas resistif berbasis semikonduktor oksida logam (MOS), dirancang untuk mengakomodasi dua keluarga sensor gas yang umum digunakan, yaitu seri MQ dan seri TGS, dalam satu tata letak papan sirkuit yang sama. Modul ini berfungsi sebagai unit kondisi sinyal (signal conditioning) yang menghubungkan sensor gas ke sistem akuisisi data berbasis mikrokontroler ESP32 DevKit V1 melalui ADC presisi tinggi ADS-1220. Modul dilengkapi resistor beban (load resistor) yang dapat disesuaikan melalui trimpot presisi, memungkinkan kalibrasi nilai resistansi beban sesuai spesifikasi datasheet masing-masing jenis sensor, serta rangkaian kontrol pemanas (heater) berbasis MOSFET yang dapat diaktifkan/dinonaktifkan secara independen melalui sinyal GPIO mikrokontroler. Modul ini merupakan komponen dalam sistem deteksi gas amonia (NH₃) berbasis multi-sensor, yang turut mengintegrasikan sensor MICS-6814 (kanal NH₃ dan RED), sensor suhu-kelembapan SHT-31, serta modul tampilan LCD Nextion Intelligent 4.3 inchi.
