Project Summary:

ICStation team has made this project about the liquid drop speed measurement system.It uses DC 5V to work. When there is no liquid in the infrared area, the buzzer will alarm and when there is liquid in the infrared area, the buzzer will not alarm. The LCD 1602 can display the drops of liquid every 10 second. You can set the drops of liquid every 10 second for reference.It is a low-cost and simple liquid drop speed measurement system. It is suitable for the areas such as works, hospital.

Full Project:

Functions

1)After the initialization of hardware, the LCD1602 will display the pre-set interface.
2)When there is no liquid in the infrared area, the buzzer will alarm and the LCD1602 will display the N on the YN column.

3)When there is liquid in the infrared area, the buzzer will not alarm and the LCD1602 will display the Y on the YN column. And if there is a drop of liquid, the display of LCD1602 will add one.

4)You can set the drops of liquid every 10 second by tow buttons.

Step 1: Lead to the power supply line and GND

Plug the +5V power supply line and GND from ICStation UNO R3 into the bread board.The red bread wire is the power supply line and the black bread wire is the GND

Step 2: The connection of LCD1602

1.Place the 1602LCD on the bread board

2.According to the schematic diagram, connect the LCD1602 module to the ICStation UNO R3

Step 3: The connection of buzzer module

1.Place buzzer module on the bread board

2.Connect the pin 1 of buzzer to the anode, pin 3 to the cathode, pin 2 of the buzzer module to pin6 of the ICStation UNO R3

Step 4: The connection of infrared receiving tube

1.Place the infrared receiving tube on the bread board

2.Connect the pin 1 of infrared receiving tube to the 220K current-limiting resistance, and then connect to the A3 pin of ICStation UNO R3.Connect the pin2 of the infrared receiving tube to cathode, and pin3 of the infrared receiving tube to the A2 pin of ICStation UNO R3.

Step 5: The connection of the infrared sending tube

1.Place the infrared sending tube on the bread board

2.Connect the anode of the infrared sending tube to the resistance and then to the anode. And connect the cathode to the GND.

Step 6: The connection of switches and limited-current resistance

1.Place the switches and limited-current resistance on the bread board

2.Connect the pin 1 of four switches to the +5V and all the pin3 to the GND, connect the pin2 of add switch to the AO, the pin2 of the decrease switch to the A1, connect the on-off swith to the A4

Step 7: The demonstration of experiment effect
