Works with any liquid water oil etc.
													
																	Oil tank sensor arduino. 
									
	
		
	
																	As the tank empties the float drops and slides a moving contact along the resistor increasing its resistance 2 in addition. 
																	For example oil may splash on it when the tank is filled. 
																	Leave a comment below if you have any doubts or queries. 
																	Arduino robot w gopro and fpv iphone control via bluetooth. 
															
													
									
	
		
	
																	It should work with any other tank having an available 2 threaded port on the top. 
																	I m also programming it in assembly using an atmel tiny2313 chip. 
																	Measure fuel level with arduino. 
																	Finally we have completed the water level sensor arduino tutorial. 
															
													
									
	
		
	
																	7 tank projects arduino robot with gopro camera and fpv function controlled from iphone via bluetooth or obstacle avoidance with ultrasonic sensor. 
																	Features of this system. 
																	What i m doing to compensate for the 25cm is to use a pipe above the oil tank input so the sensor sits higher above the tank. 
																	Liquid level sensor detects the level of the liquid from a ground level. 
															
													
									
	
		
	
																	Range up to 250 cm ground distance also height of the tank. 
																	We hope you found this project useful. 
																	I m building one but it s a couple of projects down the road but i just ordered the waterproof sensor. 
																	The sensing unit usually uses a float connected to a potentiometer typically printed ink design in a modern automobile. 
															
													
									
	
		
	
																	With the ultrasound solution i referred to earlier there is a unit in the uk that has the sensor tx link and receiver for around 50 called a watchman designed for monitoring the level of oil tanks. 
																	Now your lcd screen or serial console should be showing the water level. 
																	This sensor is designed to fit a standard american 225 gallon heating oil tank. 
																	Turns on the motor requires motor driver amplifier below a given value and turns off it above a given value after filling the liquid.
