Thursday, July 12th, 2018 - Sensor/Detection Circuit

The water level detector circuit can be created using the transistor, the detector circuit water levels has 3 levels of water level detection level. Sensors are used to detect the water level is a given transistor base pin bias voltage from the voltage source through the water. The resistance of water can be used to provide voltage to the transistor base. With conditions like that then we will get a water detection sensor. Water resistance is detected using a probe tip made of metal with a length of about 2 cm and placed on equal footing as far as 1 cm. With these conditions the water resistance is in the order of kilo ohms. With a chain and a circuit like in the picture below, the water level in a tank will be detected by the flame led.

Installation Of Water Level Detector With Transistors

To make the water level detector is thorough, then the probe circuit and transistor reproduced. To facilitate the making, the probe is placed on the pipe, then the probe connected with a long cable so it can be monitored from the ground.

The probe circuit must be treated periodically as if it has been used for a long time, the probe will be covered with mud particles will reduce the sensitivity. Water levels in the water level detector circuit with a transistor is represented using LED Flash. LED will light up when the water level touches the point where the sensor height water level detector circuit is placed.
