The PIC microcontroller is a low cost 'computers on a chip' manufactured by Microchip. They allow electronic designers and hobbyists impart intelligence and logic to a single chip for special purpose applications and products.

Proper watering is exigent for the plants and trees which are grown in containers. Many people unsurmounted to take good care of expensive plants or trees .

This article describes a DIY programmable relay switch using PIC16F1847 (PIC16F628A can also be used) microcontroller. It is a revised version of my previous PICbased relay timer project with added features and some improvements in the circuit design part.

This simple plant water alarm circuit indicates when the soil is dry and the plant needs watering. The circuit does not have a currentlimiting resistor because the base resistor is very high and the current through the transistor is only 2mA.

Remote Monitoring and Watering of plants Use GSM based add on board for remote operation Power Supply Use solar power as the power need is low. Currently i am using a power bank to power the arduino and the pump motor.

Simple Water Level Indicator By Abhay Bajpai Electronics, Hobby Circuits, Projects LED, Level, Transistor, Water 26 Comments We have already posted about a Water Level Indicator and Controller using PIC Microcontroller .

In this circuit, if R1 and Q1 are not mounted in the same environment, the precise trigger points are subject to slight variation with changes in Q1 temperature, due to the temperature dependence of its BaseEmitter junction characteristics.

Automatic Plant Watering System Introduction The Existing System The Proposed System Irrigation is the key Long gone are the days of manual watering or relying on a friend to water your plants when you are on vacation or away on business.

Some interesting Timer Circuits and Projects with schematics and easy stepbystep tutorials.

Electric circuits and electric devices pervade our modern world. Despite our planet's everincreasing need to reduce energy consumption, it appears that one of the main consumers of energy electric devices are here to stay.

Automatic Plant Watering System Circuit. The circuit below shows a simple automatic plant watering system for automatically watering your gardens, plants, etc. Frequently, we cannot set the time for watering the plants due to which the soil of the plants becomes dry.

Electronics Projects Circuit Diagrams Free 1. Introduction is making continuous effort in the field of electronics for helping electronic engineering students and electronic engineers by providing project ideas that can be used directly or added in their electronic projects.

The circuit shown here will work as a plant watering watcher or dry soil two probes shown in the diagram will detect the absence of moisture content in the soil and switch ON the relay switch at the preset value of dryness.

The water level alarm circuit is a simple mechanism to detect and indicate the level of water in the overhead tank and also in the other containers. Nowadays, all the ers/owners are storing the water in overhead tanks by using the pumps.

Jun 24, 2015· The sensor circuit is based on the 555 timer ic in astable mode. 555 timer ic vibrates at 38KHz and that waves are transmitted using IR led and if any obstacle is in front of IR led the rays reflects and the TSOP1738 IR receiver modules recieves and sends signal.

Programmable Logic Controllers (PLC) Chapter 6 Ladder Logic Before the advent of solidstate logic circuits, logical control systems were designed and built exclusively around electromechanical relays.

This is a new design of a tutorial board based on the popular PIC16F84A microcontroller. It features eight single leds, a 7segment display, an LCD display and five push buttons.

This page contain electronic circuits about Electronic VHF Circuits. This index has a wide collection of VHF circuits or schematics, that can be very useful for the enginner or the student who need a circuit / schematic for reference or information for a project that has to be in VHF band frequency at category vhf circuit : RF CircuitsCircuits and Schematics at

RGB LED control circuit 16F628 microcontroller based on the software prepared by JAL. Source code and circuit diagrams are available. According to information from the computer via serial port LEDs working with Visual Basic code for the application of resources given the necessary programs.

This electronics project Automatic Plant Watering System can be easily implemented for watering plants without human action. Circuit will automatically detect and pump water whenever needed. By using this automatic irrigation system we can avoid the chance of plants damage.

Electronic Circuit Schematics Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced.

Following that analogy, current would be how much water (or electricity) is flowing past a certain point. The higher the amperage, the more water (or electricity) is flowing. Voltage is a measure of the electrical energy of a circuit.

Wiring diagrams help technicians to see how the controls are wired to the system. Many people can read and understand schematics known as label or line diagrams. This type of diagram is like taking a photograph of the parts and wires all connected up.

through a piping network to the load (see diagram, next page), the chilled water can be pumped throughout the network to manage loads in the primary loop – the loop that circulates water through the chiller – as well as in a secondary loop – which addresses other uses on the system.
