Automated Water Tank Filler
This circuit can be utilized to maintain the water level in the header tank within specified limits. It employs a 3HP submersible bore pump that features a high starting capacity.
The proposed circuit operates by continuously monitoring the water level in...
Water Level Sensor/Detector/Monitor With Alarm
This schematic diagram illustrates a water level sensor, detector, and monitor circuit. An alarm is also integrated into this circuit. It is designed to detect any fluid with a resistance below 900K ohms.
The water level sensor circuit typically employs conductive...
High-performance automatic water level controller circuit
The circuit operates by monitoring the water level in a tank. When the water level falls below a specified point (F), the RS flip-flop (F2) is activated, producing a high Q output that energizes a relay to start the water...
Common-cathode-led-display
A Teledyne TSC7135 digital voltmeter (DVM) chip is utilized to control a multiplexed 5-digit display. To facilitate common cathode drive, a CD4513BE CMOS integrated circuit (IC) functions as a segment driver, with selection controlled by pins 17-20 of the DVM...
Induction high pressure alarm circuit
It utilizes the KD153 type "ding-dong" music integrated circuit (IC) to produce a "ding-dong" sound alarm. The reference number is 221611, and it is related to a refrigerator door alarm circuit.
The KD153 integrated circuit is designed specifically for generating melodic...
automatic water tank filler circuit diagram
This circuit is designed to fill a header tank for a reticulated water supply on a farm. It serves eight troughs located in different paddocks, where a lack of water could have serious consequences for livestock. Previously, the tank was...
LED Sound level display circuit by using IC LM3915
This is a simple audio sound level LED display circuit diagram. The circuit is entirely based on a single integrated circuit, the LM3915 from National Semiconductor. The LM3915 is a monolithic integrated circuit that displays the audio sound level using...
