Vai fantastic

Plz full name of sensor n availability?

[@etechniques]

Magnetic float switch.

I BELIVE YOU ARE MISSING SOME THING IN THE SCAMITC WHEN YOU TURN ON HIGH VOLTAGE SWITCH ON PUMPS COME ON THROUGH NORMANL CLOSE CONTACT WHEN BOTTOM SENSOR CLOSE THE LED LIGHT COMES ON WHEN TOP SENSOR CLOSE BOTH RELAY COMES ON AND STOP PUMP NOW YOUR TOP SENSOR SHORT CYCLEING THE REALY PLEASE EXPLAIN WHERE I AM MISSING THE CONNECTION THANKS

Sorry if any errors occurred while drawing the circuit. Let me check the schematic.. Thanks for watching my channel..🙂

Sorry for the late reply I have checked the circuit and there is no fault in the circuit drawing I will explain it's working 1st stage- When the water tank is empty, both float sensors will be in open condition, and the relay also. The motor will start working Since the motor is connected with Common to NC pin of the relay . 2nd stage- The bottom sensor will conduct When the water reaches the top of the Bottom sensor and both relays get a negative voltage through the sensor.(Bottom sensor is connected with supply negative) 3rd stage- When water reaches the top sensor level,the top sensor will conduct and both relays get positive voltage through the sensor ,which allows relays ON and disconnect the motor from AC line and turn OFF motor. In the circuit drawing you can see the top relay's common pin (c) directly connected to 5V+ supply which allows both relays remain ON even if the water level reaches below the top sensor. 4th stage- Finally when the water level reaches below the bottom sensor( Empty Level), Which makes the Bottom sensor open and disconnect the negative voltage to Relays and make both relays OFF . This will reconnect the AC line and Turn ON the motor ( the motor is connected with Common to NC pin of the relay .) I hope you understand my explanation🙂
