If you are familiar with the camjam edukits then you will already be familiar with a few sensors like the 1 wire temperature sensor a light dependent resistor and movement with the passive infrared pir sensor in this tutorial we are going to learn how to sense the outside world using a set of digital sensors on the tiny bmp180 board.
Digital water pressure sensor raspberry pi.
2pcs dht11 temperature humidity sensor module digital temperature humidity sensor 3 3v 5v with wires for arduino raspberry pi 2 3 2pcs dht11 3 6 out of 5 stars 21 5 99 5.
How to determine the temperature and humidity with sensors has already been shown in previous tutorials.
In particular i ll be using a water level detection sensor and a 200 psi pressure sensor.
Water pressure sensor for raspberry pi juli 26 2016 gkoper 4 reacties a pressure sensor is a necessary part of any pressurized liquid system such as a solar boiler the central heating system in a house and even a car.
Sensors add almost human sensing capabilities to your projects taking real world events and converting them to analogue or digital signals for your microcontroller to read.
The raspberry pi can also be used as a micro controller but it has a lot more functions because it runs an operating system.
It s a great way to learn how to code whilst also makin.
This tutorial demonstrates how to connect an analog sensor to a raspberry pi as well as i will deploy the project of water pressure and water level system using the raspberry pi.
Unlike arduinos the raspberry pi doesn t have an adc which stands for analog to digital converter.
For weather stations and similar projects it is often important to determine the air pressure.
A true micro controller is e g.
With the help of the barometer bmp180 the air pressure in hpa bar can be determined via the i c bus of the raspberry pi.
The arduino can also be operated very easily on and with the raspberry pi e g.
It can for example also read analog sensors.
An adc measures voltage on a pin and translates it to a number.
