Water Depth Sensors

Water tank sensorliquid depth sensor keep an eye on your outdoor water tank from the comfort of your own living room up to 100m away.

Water depth sensors.

The working of the water level sensor is pretty straightforward. S12s sdi 12 coms ip68 pressure and temperature sensor combined pressure and temperature sensor with a 1200 baud rate serial data interface as defined by the sdi 12 support group. Remotely monitor from your desktop tablet or mobile device reservoir pond and lake levels ground water well depths irrigation ditch levels and weirs. Submersible depth sensors water level sensor the sensors in this section are all hydrostatic pressure sensors that are submersible and used for measuring the level of various liquids.

In a nutshell water depth sensing is using a sensor to measure the depth of water in a tank or container. The sensors should be placed in a location where water damage could occur such as in bathrooms under the kitchen sink or in the laundry room. It also measure temperature at the same time. The higher the salinity the higher the conductivity equivalent to lower resistance.

The principle of operation of the water level sensor is based on the conductive properties of the water. Although various sensors can be used for this application we will talk about using ultrasonic technology in this application. The series of exposed parallel conductors together acts as a variable resistor just like a potentiometer whose resistance varies according to the water level. The sensor is the measurement specialties ms5837 30ba which can measure up to 30 bar 300m 1000ft depth and communicates over i 2 c.

The change in resistance corresponds to the distance from the top of the sensor to the surface of the water. With 0 2 mbar resolution it has an amazing depth measurement resolution of 2mm in the water column. Underwater pressure sensors are ip68 rated for permanent use underwater to a specified maximum water depth. Lmp307 submersible level transmitter.

It comes standard with a 4 pin df13 connector that is compatible with most flight controller boards including the pixhawk and others. Wildeye is an affordable accurate dependable water level monitoring solution. The components used for the water level sensor note that drilling some 5mm holes in the pipe is essential. The primary use for submersible depth sensors is to monitor the level of water in reservoirs rivers boreholes and various other bodies of water.

It operates on 3 3v i 2 c voltage but can accept power input up to 5 5v.
