i need a water level detector circuit. i seen above circuit but the fault is that you are working on AC6V which could be dangerous. i don’t think that we should allow ac current in water tank. could you advice some thing save or based on dc current or sensor base. besides, i am...
aFig. 2 shows the internal circuit diagram on the controller for the water level detection. The four transistors (TIP122 [13]) are responsible for getting the signal from the four wires dipped inside the water (Fig. 3) of the storage tank. Same concept of level detector is used for the...
Six electrode wires 4-1-4-6 projected down piercing the detector bodies 3 have insulating coatings stripped only at the tips and are positioned while the extents of projection are made different from 0 to 10mm. at intervals of 2mm.. When the body 1 is dropped on the water surface, ...
Fig. 2:Block Diagram of Arduino based Wireless Water Level Indicator Circuit Connections The Project has two circuit sections. One is the water level detection circuit and other is the motor control circuit. The water level detection circuit is more or less just an RF transmitter with bare wires...
A waterproof lead, a driver circuit, and a connecting wire. The testing probe consists of both the transmitter and receiver. The above image shows, this type of module uses an IR diode as a light source and an IR receiver as a detector. But the working princip...

A similar process was also conducted to compare the adsorption of CO2and generation of CO at different temperatures, which was controlled by varying the temperature of heating tape around the gas circuit (Fig.1). As the temperature increased from room temperature (20 °C) to 350 °C, CO...
An alternative known way to detect water ingress in a field device is to use an autonomous sensor inside the field device which can detect the presence of water, and such an arrangement is shown in FIG. 2. In this arrangement an electrical circuit20comprises an autonomous detector and transmit...
Designated by the numeral 40 is a detector for detecting an echo signal picked up by the receiving beam B formed by the horizontal phase synthesizer 36, and designated by the numeral 41 is a comparator which outputs an echo level "1 " or "0" depending on whether the detected signal exceed...
