This is a very simple and interesting circuit for electronics lovers. This Soil moisture sensor circuit can be used in many appliions like Automatic plant irrigation system, Greenhouse projects, etc. The circuit does not have a currentlimiting resistor because the base resistor is very high and the current through the transistor is only 2mA.
· SIMPLE PRECISION METAL DETECTOR SCHEMATIC CIRCUIT DIAGRAM. Although the metal detector circuit with the 555 timer integration is simple, it works very well. According to many metal detector circuits, the electronic component is not used, but the coil part of the detector needs a little thin workmanship. There are 2 555 timers in metal detector ...
Here the very simple and easy build gold detector circuit. The circuit capable to sense gold or metal or coins from a distance of about 20cm, depending on the size of the object to detect. The circuit oscillates at about 140kHz and a harmonic of this frequency is detected by an AM radio.
Description. This is a simple single chip metal detector circuit based on IC CS209A from the Cherry Semiconductors. A 100uH coil is used to sense the presence of metal. The IC CS209A has a built in oscillator circuit and the coil L1 forms a part of its external LC circuit which determines the frequency of
· Here in this circuit, we have used a coil having around 20 turns or winding with a 10cm diameter. We have used an empty tape roll and wind the wire around it to make the coil. Circuit Diagram: We have used an Arduino Nano for controlling whole this Metal Detector Project. A LED and Buzzer are used as metal detection indior.

Note: – PIR sensor only detect the presence of the infrared rays which comes into its range, it does not emit infrared. Related Post: Simple Touch Sensitive Switch Circuit using 555 Timer BC547 Transistor Working of Motion Detector Circuit. The PIR sensor typically operates at 5V, so we are using a positive voltage regulator IC 7805, which will give 5V output to feed the sensor.
