Using the DHT11 Temperature Sensor with the Raspberry Pi ...

2019-05-19· In this tutorial, we’re going to cover using the the DHT11 (or DHT22) temperature and humidity sensor with the Raspberry Pi.. Using the DHT11 temperature sensor with the Raspberry Pi is a great way to get temperature and humidity readings in your projects. Especially to keep tabs on how hot your Raspberry Pi is, if its in a non-ventilated box in the summer heat.

Ultrasonic Range Sensor on the Raspberry Pi - Joachim Weise

2019-12-28· The HC-SR04 sensor requires a short 10-100us pulse to trigger the module, which will cause the sensor to start the ranging program (8 ultrasound bursts at 40kHz) in order to obtain an echo response. Once the 8 burst pattern is sent, the ECHO pin is set high ( 5V), and when the signal reflects and comes back the ECHO pin is set low (0V). This ...

How to set up a Barometric pressure sensor ... -

From previous blog posts, you’ll know I have a Raspberry Pi set up to read two temperature sensors and two light sensors (inside and outside) and log the data online at COSM . Setting up temperature sensors and COSM feed. But, as ever, “we want more than that!” So I thought it would be fun to add a barometric pressure sensor. Looking around, it seemed like the BMP085 was a good bet. Even ...

Configure and read out the Raspberry Pi gas sensor (MQ-X)

Sensors are necessary to detect the components of the air. These are used in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown. Thus, smoke detectors or air quality testers can be built. How to configure any MQ sensor and read it out with the Pi ...

Interfacing MQ137 Sensor with Arduino to Measure Ammonia ...

2018-02-09· Turns out that MQ137 sensor can measure NH3, C2H6O and even CO. But, here I am interested only in the values of NH3. However you can use the same method to calculate ppm for any sensor you like. This graph is the only source for us to find the value of ppm and if we could somehow calculate the ration of Rs/Ro (X-axis) we can use this graph to find the value of ppm (Y-axis). To find …

Android Sensors as IMU for Raspberry Pi 2 via USB and UDP ...

This is not convenient as you need to know the Raspi IP in order to send the sensor data to it. If the Raspi IP changes every time you connect it to the phone, you will need to look for the Raspi IP and change your configurations in the phone in order to use the new IP. This can be avoided by telling the Raspi to set a specific static IP. I searched how to do this and found some places where ...

Monitor air quality with a Raspberry Pi - Raspberry Pi

2019-07-21· Add a sensor and some Python 3 to your Raspberry Pi to keep tabs on your local air pollution, in the project taken from Hackspace magazine issue 21. Air is the very stuff we breathe. It’s about 78% nitrogen, 21% oxygen, and 1% argon, and then there’s the assorted ‘other’ bits and pieces – many of which have been spewed out by humans and our related machinery. Carbon dioxide is ...

How to Interface a PIR Motion Sensor With Raspberry Pi ...

2018-03-23· The sensor outputs a 5V signal for a period of one minute as soon as it detects the presence of a person. It offers a tentative range of detection of about 6–7 meters and is highly sensitive. When the PIR motion sensor detects a person, it outputs a 5V signal to the Raspberry Pi through its GPIO and we define what the Raspberry Pi should do as it detects an intruder through the Python …
