The AUTOMAN mode can be toggled at any water level using the AUTOMAN push button switch.
Water Level Sensor Arduino Install A WaterTherefore, many people install a water tank on the roof of the building.The water, stored in a water tank at the basement (ground) is pumped into the water tank on the roof using a pumping motor.In this manner, the limited water-availability problem can be improved and the water can be used in a more efficient way if an automatic water tank pump controller is included in the setup.Traditional water level controller can control the water between two levels with the help of floating ballsfloat switch as the sensors for level detection. However, the controller unit is usually placed at the top of water tank, humidity may corrode the contact points of the sensor switch. Meanwhile, since there are no means to detect the water level of the basement water tank, it is possible that the pumping motor will be burned if there is very lowzero water level in the basement water tank. Here is a simple yet effective water tank pump switcher circuit, realized using the renowned AVR microcontroller Atmega328P-PU. The circuit can be used to maintain the level of water in the overhead water tank within prescribed limits. Water Level Sensor Arduino Software Can DetermineFrom the reading of the water level detection ports, the internal software can determine the water level of the overhead water tank. Note that E 2 PROM storage option of the microcontroller is also used here. The basement water tank level sensor is another simple (1-point level) float switch, added as a dry-run protector. Hermetically sealed-in-glass reed switches located inside the stem are activateddeactivated by the upwarddownward movement of the strong magnet in the tailpiece of the float. An on-board linear voltage regulator is included in the system to provide a clean dc supply to the whole electronics circuitry. Try to use a magnetic float switch that activates two reed sensors so that the float (with magnet) should terminate its travel in front of L and H reed sensors. If the L sensor triggers its microcontroller input, the water pump is activated. Now the STANDBY indicator LED goes off, and PUMP ON on indicator LED lights up. When H level is reached, ie the H sensor triggers its microcontroller input, water pump is deactivated. Now the PUMP ON indicator goes off, and the STANDBY indicator lights up again. Water pump is reactivated only when water drops back to L level. As a result, the system immediately deactivates the water pump to protect the electric motor of the water pump. In MANUAL mode, water level detection process is overridden and the water pump keeps working endlessly. Simultaneously, MANUAL mode indicator LED lights up as a warning indicator.
