Water tank level sensor circuit.

Ultrasonic liquid level sensor water tank liquid depth level meter sensor with temperature sensor water level gauge digital level measuring meter digital display. In the shown circuit the pin7 sensor will go to the tank full level or the brim of the sump tank pin1 will go to the full level or the brim of the oh tank. The circuit is designed so that the buzzer will start beeping once the water tank is completely full. Q1 comes on as soon as water level drops below pump protect.

Q1 base current is too small less than 1 micro amp. Madison m5000 liquid level sensor miniature float switch stainless steel 1 8 npt 3 0 out of 5 stars 6. You can also use this device to sense the water level at a determined level. Automatic water level controller circuit each sensors float is suspended from above using an aluminium rod.

The circuit produces the sound when the sensor senses a drop of a water leak. In this circuit this circuit uses a liquid level sensor to measure the level of water in the water tank. In fact the level of any conductive non corrosive liquids can be measured using this circuit. The circuit is very simple to build with the microcontroller and also using basic electrical and electronic components.

This arrangement is encased in a pvc pipe and fixed vertically on the inside wall of the water tank. Such sensors are more reliable than induction type sensors. When the sump tank is full it will switch on the motor when the oh tank is full it will switch off the motor. Taidacent non contact liquid level sensor water tank level sensor water level control low and high level output 3 6 out of 5 stars 15.

Each transistor is switched on to drive the corresponding led when its base is supplied with current through the water through the electrode probes. The circuit is based on 5 transistor switches. How the sensor works is very simple the metallic sensor is dipped into the tank when water touches the two metallic strips simultaneously it bridges the separation between the strips thereby creating a poor conductive path for electric current to flow from one strip to another. The circuit formed by transistors q1 and q2 is designed to turn on the red led pump protect whenever there is no water between pump protect electrode and ground electrode at pump reservoir.
