Introduction The following diagram shows the system schematic of the Smart Plant Feeder. It contains the several major blocks: ATmega 323 is the CPU of the system. 5 VDC power supplier: an adaptor first transforms 110 VAC 60 Hz into 9 VDC; then a regulator keeps VCC stable at 5 VDC. A crystal of 32KHz […]

Three-fourths of the earth is water, out of which 97 per cent is saline (in oceans, seas and groundwater). The remaining 2.5 per cent to 2.75 per cent is fresh water, out of which 1.75 per cent to two per cent is frozen in glaciers, ice and snow. Fresh groundwater and soil moisture constitutes only

Sometimes the float valve of a water tank may not work properly causing water to overflow and spread across the floor. Peter Jennings faced this problem in his storage area, and he had developed an alarm device to notify him when the water exceeds its normal range. Peter’s project includes a simple water sensor and

Using microfluidic passages cut directly into the backsides of production field-programmable gate array (FPGA) devices, Georgia Institute of Technology researchers are putting liquid cooling right where it’s needed the most – a few hundred microns away from where the transistors are operating. Combined with connection technology that operates through structures in the cooling passages, the

The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container. The sensing is done by using a set of nine probes which are placed at nine different levels on the tank walls (with probe 9 to probe 1 placed in increasing

Honolulu, HI (PRWEB) August 23, 2006 (Nanowerk Spotlight) Conventionally, the fabrication of thin film nanostructures is primarily done by using selective etching or templating growth on a prepatterned resist and then performing lift-off. The solvents used in developing resist are typically toxic and add to the cost of lithographic processing. Recently, many environmentally friendly lithographic
