Water Level Indicator Circuit Diagram and Sensor Arrangement.
Fridge Door Open Alarm.
I am also working on a float type water level indicator/controller using the float type fuel gauge mechanism used in motor e level sensor section is firestore dv file converter pro finished and now I am working on the control circuitry.
The type number of the transistors used here are not critical and any small signal NPN transistor will do the job.In fact the the level of any conductive non corrosive liquids christmas tree storage box canadian tire can be measured using this circuit.Thats what I got and is still going.One electrode probe is (F) with 6V AC is placed at the bottom of tank.So this setup will last really long.Try the circuit first on a bread board and if not working properly, make adjustments with the resistance values.We have more circuits and applications that you may like;Take a look below:.The circuit is based on 5 transistor switches.I will add the circuit here as soon as it is finished.AC voltage is use to prevent electrolysis at the probes.Color of your choice, notes: Use a transformer with 6V 500 mA output for power supply.This is often needed because conductivity of water changes slightly from place to place.Other probes are placed step by step above the bottom probe.Arrange the probes in order on a PVC pipe according to the depth and immerse it in the tank.The ends of probes of the water tank level indicator are connected to corresponding points in the circuit as shown in circuit diagram.Fan Regulator Circuit.Few transistors, one 555IC and an electromagnetic relay is used for realizing the control section.This in turn makes the transistors conduct to glow LED and indicate the level of water.I guarantee at least a 2 years of maintenance free operation.Insulated Aluminum wires with end insulation removed will do for the probe.Water is at the center of economic and social development; it is vital to maintain health, grow food, generate energy, manage the environment, and create jobs.
Resistors (R1 to R5).2K 1/4 W, resistors (R6 to R10) 22K 1/4 W, lED's (D1 to D5).
