Water Tank Level Sensor Raspberry Pi

Many of these use magnetic reed switches that never touch the water even when fully submerged.

Water tank level sensor raspberry pi.

The raspberry pi reads the status of one or two water sensor device s on one or two of its gpio pins. The plus and minus pins go to 3 3 v and ground respectively. The meter will need to be calibrated to get an exact volume measurement. The hcsr04 is placed on the roof of water tank.

I have another tank that needs a level sensor added maybe with a temp and humidity sensor on it too. I am going to share about how to build a water level sensor for water tanks with a raspberry pi. Water level sensor is simple and cheaper sensor that identify the amount of water through exposed parallel line track easy to complete analog signal change from the water level detection the work voltage of this sensor is dc 3v 5v and use 3 3v in this tutorial. The water level sensor s s pin is connected to ch0 adc channel 0.

They are essentially single pole switches which are closed when the water level is higher than it and open when the water level is below it. The schematic shows a raspberry pi a but this set up will work on any pi. There are many ways to measure. It s tough bilge pump float sensor.

The flow meter on the dual house pumps that switch over when one fails and measure how much water we use would be perfect. Mcp3008 as adc chip is very common and recommended highly. When water is detected the raspberry pi emails out an alert to a recipient group and calls a phone number list via voip playing a stored wave file with a spoken alert phrase. Introduction hello everybody i am shafin a member of aiversity.

Using a yf s201 flowmeter on a raspberry pi the code uses python to populate a database. Size maybe has to touch the water. Version 1 0 published in jan 2015. An optional bi color led connected in series with 330 ω resistors to gpio 14 and 15 provides feedback.

Water level monitor with raspberry pi.
