How to Make Automatic Hand Sanitizer, Hand Wash

Programe Link https://drive.google.com/drive/folder... 12 V DC Pump is connected with the arduino through the relay .As the Ultrasonic Sensor Detect the hand it gives the signal to the arduino and than the arduino will give signal to the relay and relay will on the pump for the 170ms. By increasing and decreasing this time we can change the flow of the liquid..As the pump will be on it will send the high pressure air to the bottle.The bottle is air sealed ,having no leakage so the the air will displace the water air will move downward and the water will move upward through the pipe..due to the low pressure...the pressure inside the bottle will be more than the atmospheric pressure..so the water will try to escape from the bottle..the time for whole preocess is 5 sec in this time period the sensor will not take the signal again if hand is still infont of the sensor. The dc socket of the arduino is using for the supply for both pump and arduino...Here i am using 12 V 1 A adapter 9 V Will also be enough.. The main casing is made up of the acrylic sheet..
