WhatsApp Based Notification on Low Battery Water Level Using ESP Module and TextMeBOT

Abstract

Purpose: Nowadays, we can not imagine any day without electricity. In suburban areas, frequent power cuts happen. Most of the time, electricity is unavailable in the village area to balance the demand and available power supply. So we install the power inverter in our house for an uninterrupted power supply. This high-power inverter runs using a wet-cell battery, the widespread domestic power inverter field battery. The only drawback is we need to fill the battery with water when it goes low. It gets damaged if we keep the battery at a low water level for a long time. In our busy schedule, most of the time, we forget to check the battery water level. In most scenarios, the battery is inside the enclosed trolly. Every time, it is not possible to open the trolly and check the water level. Using the IoT technology, we can solve the problem nicely. So here we provide a procedure to get informed through WhatsApp when the battery water level goes down.

Methodology: This project uses several electronic components. The heart of the project is the ESP module, a low-cost wifi controller. We operate six infrared(IR) modules for measuring battery water levels. This module is connected to six digital inputs of the ESP module. We use a one-cloud service, TextMeBot, to send the message to WhatsApp. Cloud services are responsible for transmitting the message to the given Whatsapp number. When the system starts, it will establish communication with the internet through a Wi-Fi router using the provided credentials. Once the connection is established, it is ready to send the message. When the water level is below average, it triggers the esp module. It senses the controller and sends the message to the predefined WhatsApp number.

Findings/Result: the frequent power cut is the current electricity issue. Due to the heavy electricity demand, sometimes a power cut happens. For the uninterrupted domestic electricity, we install an inverter. The wet cell battery provides good power capacity and low cost. The water, after a couple of months, goes empty. This system protects us from battery damage due to low water levels. We installed it in the practical field, running for years without issues.

Originality/Value: We generally check the battery water level by observing the level indicator that comes with the battery by default. We check the water just after certain month intervals. If empty, we fill the water. But in busy life schedules or inaccessible places, we cannot check the water frequently, so the battery generally gets damaged. So, using this system will protect us from severe damage to the battery from low or empty water. So, this system provides value to us.
