Simple Automatic Plant Watering Circuit for Monitoring Soil Moisture
This automatic plant watering circuit can be used for automatically sensing soil humidity and triggering a water pump when the ground gets parched below a predetermined level (adjustable). Circuit Operation The circuit is rather straightforward and uses a single IC 555 as the main active component.Referring to the automatic plant irrigation circuit shown below we […]
Simple Shop Shutter Guard Circuit to Safeguard your Shop from Theft
The shop shutter guard circuit discussed here guards your shop when its shutter is closed i.e., at night if an intruder tries to break the shutter, the piezo senses the vibration and the relay is fired to which a 230 volt bulb can be connected which makes the intruder think that someone’s inside…..but he doesn’t […]
