Description

According Circuitstoday blog mentioned that This project is about a moisture-sensing automatic plant watering system using 8051 microcontroller. The system simply senses the moisture level and switches on the irrigation pump when the moisture is below the set limit. The system switches off the pump when the moisture rises above the set point. The moisture level threshold can be set using a trim pot on the system. The status of the pump (whether ON or OFF) is displayed on a 16×2 LCD display. The system can be divided into three section as follows.

Sensing prob.

YL 69 moisture sensing probe is used to sense the moisture here. It is simply a fork-shaped PCB with tracks running on both sides of the legs.  Just plug this probe into the soil where you want to sense the moisture.

Comparator circuit.

YL 38 comparator module is used in this project. It is a single channel opamp comparator based on L393 IC. This module just compares the output voltage of the sensing probe with a reference voltage and switches its voltage appropriately for the microcontroller to read.

And this circuit has a few parts and easy to buy in most of the local markets.

The AC-voltage to the power cord, transformer T1 changes 230VAC(PRI) to about 24VAC(Sec). Then, the rectifier bridge, D1 through D4, rectifies the AC into pulsating DC.

Next, A big electrolytic capacitor-C1 filter the pulsating DC to smooth DC voltage about of 36V. But this is not complete. Because of It is not DC regulated voltage of 24V at 2A.

After that, the DC voltage flow through the R1 to Zener Diodes (ZD1, ZD2) to keeps the voltage constant at 25V. This voltage across the base of Darlington transistor Q1 to bias it working full current more than of 2A.

The capacitors C2, C3, C4 acts as a storage capacitor to reduce the noise of output. This makes constant voltage across the output of 24V. The LED1 show power on of circuit, which the R3 is its limiting current resistor.

• LEDs
• Power Supply

Description

This is electronic circuit of Simple Analog to Digital Converter using ADC0808 for you. According Electronicszone blog mentioned that Normally analogue-to-digital con-verter (ADC) needs interfacing through a microprocessor to convert analogue data into digital format. This requires hardware and necessary software, resulting in increased complexity and hence the total cost.

The circuit of A-to-D converter shown here is configured around ADC 0808, avoiding the use of a microprocessor. The ADC 0808 is an 8-bit A-to-D converter, having data lines D0-D7. It works on the principle of successive approximation. It has a total of eight analogue input channels, out of which any one can be selected using address lines A, B and C. Here, in this case, input channel IN0 is selected by grounding A, B and C address lines.

Usually the control signals EOC (end of conversion), SC (start conversion), ALE (address latch enable) and OE (output enable) are interfaced by means of a microprocessor. However, the circuit shown here is built to operate in its continuous mode without using any microprocessor. Therefore the input control signals ALE and OE, being active-high, are tied to Vcc (+5 volts). The input control signal SC, being active-low, initiates start of conversion at falling edge of the pulse, whereas the output signal EOC becomes high after completion of digitisation. This EOC output is coupled to SC input, where falling edge of EOC output acts as SC input to direct the ADC to start the conversion.
As the conversion starts, EOC signal goes high. At next clock pulse EOC output again goes low, and hence SC is enabled to start the next conversion. Thus, it provides continuous 8-bit digital output corresponding to instantaneous value of analogue input. The maximum level of analogue input voltage should be appropriately scaled down below positive reference (+5V) level.

Description

According Circuitstoday blog mentioned that this tutorial we are going to control a robot driven by two DC motors by simply using hand movements. There are different kind of sensors to detect your hand movement like flux sensors, Accelerometers and other gravity based sensors. So for wireless transmission we are going to use RF 434 module which transmit 4 bit data. 4 bit data means you can transmit 16 different combinations i.e., 0000 to 1111. Further in this tutorial we will use an encoder and decoder to avoid interference in the air interface. A motor driver will drive the motors from using the decoder data.

We use our Raspberry pi at the transmitter end to analyze the sensor data and to transmit a data combination to the motor driver to drive the motors accordingly so that the robot can hover around. We will be using a 12 V battery on robot to power the decoder module, receiver module and the motors. At the transmitter end sensors and transmitter encoder module is powered by raspberry pi itself.
