PROJECT DESCRIPTION

Flood monitoring using Wizfi360-EVB-PICO

Introduction:-

Flood natural calamity which cannot be avoided totally every year the collateral damages increases due no early warning. To solve this problem, we demonstrates the idea and implementation of a Flood Monitoring and Alerting system using Internet of Things (IOT) technology To develop A Real Time Solution to Flood Monitoring Using IOT and Sensor Network, we proposed a flood warning system which requires attention to three basic factors: Data collection via gauging, data processing, and the hardware and software used, and the lack of flood warning information. The automated flood warning systems are surprisingly inexpensive to build, the factor which affect cost for any such system is the number of site locations where sensor should be implemented.

In this project, we will make Flood Monitoring System using Raindrop Sensor & Raspberry Pi Pico. A raindrop sensor is basically a board on which nickel is coated in the form of lines. It works on the principle of resistance. The rain Sensor module allows to the measurement of moisture via analog output pins and it provides a digital output when a threshold of moisture exceeds.

It stimulates the flood control alarm system, judges whether there is a flood disaster through the amount of rain detected by the sensor panel of the raindrop sensor, and then controls the buzzer to emit a siren sound

  • Built-in LDO 

 

2. Rain Sensor:-

A sensor that is used to notice the water drops or rainfall is known as a rain sensor. This kind of sensor works like a switch. This sensor includes two parts like sensing pad and a sensor module. Whenever rain falls on the surface of a sensing pad then the sensor module reads the data from the sensor pad to process and convert it into an analog or digital output. So the output generated by this sensor is analog (AO) and digital (DO)

  • Operating voltage ranges from 3.3 to 5V
  • The operating current is 15 mA
  • The sensing pad size is 5cm x 4 cm with a nickel plate on one face.
  • Comparator chip is LM393
  • Output types are AO (Analog o/p voltage) & DO (Digital switching voltage)
  • The length & width of PCB module 3.2cm x 1.4cm
  • Sensitivity is modifiable through Trimpot
  • Red/Green LED lights indicators for Power & Output

 

3. Buzzer:-

  • Rated Voltage: 6V DC
  • Operating Voltage: 4-8V DC
  • Rated current: <30mA
  • Sound Type: Continuous Beep
  • Resonant Frequency: ~2300 Hz 
  • Small and neat sealed package
  • Breadboard and Perf board friendly
