Simple Water Level Indicator with Alarm (3 Tested Circuits) Generally, water stored in overhead tank is wasted due to over flow ,when the tank is full. Water level alarm using micro controllers like 8051 and AVR are shown in previous articles.This article shows simple circuits of water level indicator with alarm. Water Level Indicator Project Circuit Working using AVR This Water Level Indicator project circuit is designed using AVR to detect and indicate the water level in an overhead tank or any other water container. Water Level Indicator With Alarm: 5 Steps (with Pictures) Water Level Indicator With Alarm: Introduction Today I am going to talk about a very useful project that I had taken up. It is called the Water Level Indicator. Nowadays everybody has overhead tank at their homes. But everyone who has a water tank above knows the kind of problems ... Water level sensor circuit: projects for school students ... I have posted wide varieties of small electronic projects on water level sensor in Circuits Gallery.This is another project for school students to detect the water level inside a water tank or any other water reservoir. We can call this as a ‘liquid level sensor’, because this circuit is able to sense the presence and absence of liquid in a tank.This school electronic project is built ... Numeric water level indicator liquid level sensor circuit ... Numeric water level indicator liquid level sensor circuit diagram with 7 segment display Engineering project Gallery of Electronic Circuits and projects, providing lot of DIY circuit diagrams, Robotics & Microcontroller Projects, Electronic development tools ELECTRONIC 555(100) contact.bg The heart of this circuit is IC No. 555. When the alert sound was working, even though the switch will continue to be the same, the sound still does not stop immediately.But it will stops automatically, when a set time period,Depending on the resistance of R3, the circuit so I set a time period equal to 1M for 1 minute 6 seconds. 100 IC Circuits Talking Electronics 555 ASTABLE OSCILLATORS Here are circuits that operate from 300kHz to 30 minutes: (300kHz is the absolute maximum as the 555 starts to malfunction with irregular bursts of pulses at this high frequency and 30 minutes is about the longest you can guarantee the cycle will repeat.) 8051 Electronic Circuits and Diagrams Electronic ... This article is about interfacing GSM module to 8051 microcontroller. GSM module has become a very commonly occurring hardware in embedded system applications and the knowledge on how to interface GSM module with microcontroller is very essential if you want to become a good embedded system designer. GSM based SMS Alert Fire Alarm System using Arduino In this article,we are going to build a Fire Alarm System using Arduino, LM35 Temperature Sensor and GSM Module. The objectives of this fire detector using arduino is to sense the surroundings for occurrence of fire with help of LM35 temperature sensor, and send 3 SMS alerts to two mobile numbers stored inside the arduino program if fire is detected (using GSM Module). 4541 Timer Relay Circuit 0.3 second to 10 hours Use the potentiometer for setting the timing period within these intervals. For the 0.3 second to 10 minutes timer version the potentiometer is 100kΩ, R1 = 9.1kΩ, R2 = 910kΩ, R3 = 220kkΩ and C1 = 100µF. Digital Door Lock using Arduino Keypad Number Lock As thefts are increasing day by day security is becoming a major concern nowadays. In this project we will make a digital door lock system with keypad using Arduino Uno.It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. Battery Charger Circuits | CircuitDiagram.Org A good designed circuit of a Alkaline battery charger. The interesting thing of this circuit is that it uses a led that will show the charge of battery by blinking, when you connect a totally discharged battery the LED blink faster but when the battery charging process starts the LED blinking speed will dicrease slowly and completely stop when the battery will fully charged. What are Different Types of Sensors with Circuits? Different Types of Sensors in Electronics. In our day to day life we got used to use different types of sensors frequently in our power systems such as electrical and electronics appliances, load control systems, home automation or industrial automation, and so on. Thermistor A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.The word is a portmanteau of thermal and resistor.Thermistors are widely used as inrush current limiters, temperature sensors (negative temperature coefficient or NTC type typically), self resetting overcurrent protectors, and self regulating heating elements (positive ...
