This is the 560th scientific experiment pushed by the explosion laboratory
A small experiment every day, take a baby to play as a scientist
Water dispenser is a very common electrical appliance
general water dispenser
We need to press the switch with your hand or cup
water dispenser to release water
But today it explodes
I want to take everyone to make a smart water dispenser
As long as there is a cup close to the water dispenser outlet
water dispenser will release water
How is this implemented?
Hurry up and try it with the burrow!
- Smart water dispenser -
foam glue x6/water pump x1/battery box x1/long rod x1/large plate x1/hose x1/ cable tie x4/wire 1x6/wire 2x2/wire 3x2/relay module x1/induction module x1/fixed plug x1/part package x1
3mm screw x10/10mm screw x6/small white column x1/small iron sheet x1/switch x1
step1
Connect the middle interface of the switch and the red wire of the battery box together
Connect the interface on one side of the switch to a wire 3
step2
Translate the OUT interface of the sensing module and the IN interface of the relay module
Link it together with the wire 2

step4
loosen the screw on the "long opening" interface of the relay module
Insert the red line on the water pump
tighten the screws to fix the red wire
step5
Link a wire in the "public" interface of the relay module
in the same way 3
step6
Tighten the wires on the induction module "VCCh"
on the relay module "VCC"
on the relay "common end" and one wire on the switch
4 wires tighten together
step7
Wire on the induction module "GND"
Wire on the relay module "GND"
Black wire on the water pump
Black wire on the battery box
4 wires tighten and link together
step8
Install the battery in the battery box and turn on the switch
Test whether the water pump is running
step9
relay module bottom with foam glue
fixed on the large board
fixed with screws in the center of the large board
step10
Fix the bottom of the relay module with foam glue
Fix it on the large board
Fix it on the center of the large board with screws to fix the plug
step11
In the water outlet of the water pump, install the rubber water pipe
step12
In the four corners of the large board, install small white columns with screws
step13
Fix the small white column with screws at one end of the long rod
step14
Fix the plug with screws on the small white column
step15
Fix the water pipe between the small iron sheet and the fixed plug
Fix the screw with screws on the small white column
step16
Insert the long rod into the fixed plug on the large plate
Fix the transparent water cup with foam glue on the large plate
Put the water pump into the transparent cup
step17
Fix the rubber water pipe on the long rod with a tie
step18
Take out the wire of the switch
Install the switch on the large board
step19
Then relink the wire and switch of the switch
step20
The two induction receivers on the induction module
bend 90 degrees
Use foam glue to fix the induction module on the bottom of the long rod
Pour water in a transparent plastic cup
so that our smart water dispenser is finished!
step21
Open the switch
Pick up the water cup and get close to the sensing module
Experience the fun of the water dispenser automatically coming out
Is your water dispenser manual button
or automatically sensing?
After watching this experiment
Do you also want to make an intelligent induction water dispenser by yourself?
Then start!
I heard that some parents and classmates
put the water pump in the barrel of water
transformed a smart water dispenser that can be used in daily life in
!
Do you want to try it?
The core reason why the intelligent water dispenser can automatically discharge water is induction module .The sensing module can sense the object to be close to. When the cup is close to , the sensor senses the object to allow the circuit to turn on , and the water pump starts up and pumps the water up. After the cup took away , the sensor could not sense the object, causing the circuit to disconnect , so the water pump stopped working and the hose stopped water.

Smart water dispenser experiment in explosion box-gift special edition , this is a scientific knowledge gift prepared for children.
Xiao Wang said that remote control planes, clothes, shoes, and children from relatives are basically there. It is really difficult to find a small gift that is liked, fun and meaningful for children.
Ms. Li wants to give gifts to customers. If you buy a toy, it will take hundreds or even thousands of times at any time. It is inappropriate to be too expensive and it is too cheap. Customers will look down on it. I would like to know what meaningful and valuable gifts to the client's children.
So Burst has also prepared this different scientific knowledge gift for everyone - explosion box - gift special edition .
To facilitate everyone to send parent-child, friends, customers and children, 4 boxes only cost 50 .
