![]() FOR the LCD we will use I2C to connect to the microcontroller. By using the schematic above for the wiring configuration. Next, we set up another microcontroller that will be connected to RFID and LCD 16x2. If(distance1 0 & distance2 5 & distance2 10 & distance2 15 & distance2 < 20)īlynk.notify("Water tank need to be "Water Tank Alert", "Water tank need to be refill") Serial.print("Hasil Sensor dispenser: ") ![]() When the water level is low by using Blynk.notify() and Blynk.email() the software will send and notify email to the user to refill the water tank.īn() is essential in the main function for it is used to connect the microcontroller to the Blynk application void loop() Blynk.virtualWrite will update the data to Blynk software of the water level. the system will update to the Blynk software the water level by using the ultrasonic sensor. the main program will update the system and keep track of the water level. In this code below is the main program the water dispenser. Thereby applying the method of distance = (speed * time)/2 we will be able to get the actual distance of the object to sensor. The ultrasonic sensor will send a vibration to echo and catch back it through the trigger pin. In the code below is the code for the Ultrasonic sensor to measure the distance of the object detected to the sensor. #define BLYNK_PRINT Serial // Comment this out to disable prints and save spaceįloat time1 = 0, distance1 =0, time2 = 0, distance2 = 0, tinggi2 = 0 In order to use Blynk, we use Blynk.begin() in the setup function and give the essential parameter such as Blynk authentication, SSID and pass to access the Blynk project. ![]() In the code below is the setup configuration to use the hardware and Blynk software. Then use the code below to test the ESP WIFI is working fine as needed. Include BLYNK and ESP8266WiFi library to Arduino IDE software. The next step will be including the library in the Arduino IDE. For the pipe use a better pipe that usable for drinking and connecting it to the pump so the system could pump out the water.Īfter connecting the pin of the component to the circuit. ![]() In the relay, we connected the motor to NO of the relay so that when the relay is activated the motor will start working and pumping the water. In this system, the data will be sent to the application is the water level of the dispenser. The ESP will work as the connection to the WiFi Module. Power Saving Function: When using only one sort of water temperature between hot & cold, you can turn the other temperature switch off and save electric.Firstly, wire the component as the schematic diagram as above.Water Level Control Function: Automatic water level control function ensures durablity of the filters & unit.įresh Water Supply: 4~12 of cold water and 70~90 of hot water are available at any time. Safety Functions for Hot Water Use: Anti-Superheating function of heater (by manual reset type of bi-metal) & automatic temperature control function (by automatic reset type of bi-metal) keep you safe from hot water. Hot Water Safety Button: An extra safety button can protect your children from unexpected accident with hot water. Reverse Osmosis Filtration System: >0.5 μm Sediment Filter (filter larger particles and solid impurities), Pre-Carbon Filter (absorbs chlorine, mould), >0.001 μm RO Membrane (removes bacteria, viruses, heavy metals, pesticide residue), Alkaline Post Filter (regulates the taste of water and keeps the water fresh). ![]() Removable Water Faucets: Easily removable water faucets will be a hygiene guard to help keep hot & cold water faucets always clean. Eco Mode: The ECO sensor automatically stops water heating & chilling and save electric charge, when it notices that illuminance around the unit darkens at night.Ĭontinuous Water Dispensing Function: By this function, you can conveniently receive a large ![]()
