ESP8266
ESP8266 is a Wi-Fi module developed by Espressif Microcontroller Systems. In the board is a microcontroller unit And a built-in Wi-Fi Chip, It is the low-cost solution for Wi-Fi connectivity to various projects.
16×2 LCD Display
- This is a basic 16-character by 2 lines Alphanumeric display. Black text on Green background. Utilizes the extremely common HD44780 parallel interface chipset. Interface code is freely available.
GSM module (SIM800l)
GSM SIM800L is a popular module that enables communication over GSM (Global System for Mobile Communications) networks. It Sends a text message and calls to a particular Mobile Number. and is necessary to put a valid SIM card in the GSM module.
- The module requires a power supply of 3.7 volts. It can be powered using an external Battery.
Ultrasonic Sensor
- Ultrasonic sensors find out the distance of the water level of the dam. And the Sensor mount on the top of the dam.
- Ultrasonic Sensor required a 5v power supply.
Float Sensor
Float sensors to detect Water levels. They consist of a float, on the water, and when the water level increases the float mechanism goes to the Top and is given the alert information.
