Water Depth Sensor Raspberry Pi
So i went for the raspberry pi 3.
Water depth sensor raspberry pi. These raspberry pi sensors are addressed via the so called 1 wire bus. However these modules can not measure additional information such as humidity and or air pressure. The character lcd display only uses the two i2c pins on the pi. There were two types of ultrasonic sensors i.
Ultrasonic vs pressure sensor. When used in conjunction with a pull up resistor it can be used as a digital device to indicate the presence or water. An optional bi color led connected in series with 330 ω resistors to gpio 14 and 15 provides feedback. Which sensor should i use.
Raspberry pi ultrasonic distance sensor. The water level sensor s s pin is connected to ch0 adc channel 0. Set up a raspberry pi temperature sensor my hydropi this tutorial will show you how to set up the 1 wire ds18b20 waterproof temperature sensor on your raspberry pi. The ds18b20 and ds18s20 represents a very simple sensor.
The plus and minus pins go to 3 3 v and ground respectively. Tech specs for the water level sensor module. Something like this sorry for the bad inkscape drawing that z line should be at the bottom of the ball not the top. The schematic shows a raspberry pi a but this set up will work on any pi.
I looked at 2 different types. The water level sensor leak detection sensor is a 3 pin module that outputs an analog signal generally 0 to 500 that indicates the approximate depth of water submersion. The setup uses the adafruit rgb positive 16x2 lcd keypad kit for raspberry pi which allows a red or green backlight indicating visually the status of the water sensor. Connect multiple sensors to the pi using just one pin.
Water sensor water level sensor is an easy to use cost effective high level drop recognition sensor which is obtained by having a series of parallel wires exposed traces measured droplets water volume in order to determine the water level. Alteratively the monochrome sister kit can be used however without the coulor visualisation. An advantage is that many different 1 wire components can be connected in series and read out by a single gpio.
