Rancang Bangun Alat Penghitung Jumlah Penjualan Air Galon Isi Ulang Menggunakan Sensor Zmpt Ac Berbasis Nodemcu
Refillable gallon water is an essential need for modern society, given the convenience and practicality it offers. However, managing the sales of refillable gallon water often faces challenges such as lack of employee supervision and difficulties in profit calculation. This study aims to design and develop a Refillable Gallon Water Sales Monitoring System using the ZMPT AC sensor based on NodeMCU, integrated with the Telegram platform. The method used involves collecting voltage data from the ZMPT AC sensor installed on the water filling switch, which is then sent to the NodeMCU. The NodeMCU processes the data and automatically sends sales reports to Telegram, allowing business owners to monitor sales in real-time.
Keywords : NodeMCU, ZMPT AC 101B Sensor, Telegram Application.
