RETIRED PRODUCT - We've stopped stocking this product or it has been retired by the manufacturer and is no longer for sale. This page remains available for its resources and as a source of potential interest.
The electronic projects for the garden book offers some simple circuits that will monitor weather and environmental conditions and provide warnings or take remedial action as necessary. For example, such projects include rain detection, frost warning, under/over temperature monitoring, dusk/dawn switching and automatic plant watering.
Although library shelves and bookstalls bulge with a bumper crop of gardening books, surprisingly few pages are devoted to electricity and fewer still to electronics.
It's no secret that sucess in the garden is largely dependent on the elemenst; keeping a weather eye is important for protecting those tender shoots. You can't control the elements, but you can use them to control your results - by courtesy of electronics!
Raking through the chapters, you will find such interests as security devices, process timing, warming cables for propogators, ponds and pumps, and the low-down on low-voktage circuits for lighting schemes.
To encourage beginners branching out in electronics, some construction methods are introduced using breadboard layouts, or screw terminal blocks to obviate soldering.
Note: In the interests of safety, all projects are powered by low-voltage supplies.
